Vertical roller mill is an important grinding equipment in industrial production. During the operation of vertical mill, sometimes the vertical roller mill can not work normally, then it needs to stop and repair the vertical mill. Investing in re-production, so it is crucial to understand the factors affecting the normal production of vertical mills. What are the factors that affect the normal production of vertical mills?
1. The quality of the vertical mill is not good. The quality of the vertical mill is one of the important factors affecting the normal production of the vertical mill. The better the quality of the vertical mill, the more stable the operation and the smaller the vibration, which is an important guarantee for the continuous and efficient production of the vertical mill. On the contrary, the quality of the vertical mill is flawed, so there will always be problems in the operation process. Therefore, the quality of the vertical mill affects the normal production of the vertical mill.
2. The running-in degree between the gears of the vertical mill is not good. According to the working principle of the vertical mill, if the vertical roller mill is running poorly between the equipments during operation, if there is a gap between the gears, the vertical mill will give an abnormality during the operation. The sound will also affect the normal operation of the vertical mill.
3. The vertical mill lining is seriously worn. In the grinding process of the vertical mill, some materials have relatively high hardness. The vertical mill has very serious wear on the lining during the grinding process, which requires the user to check the wear degree of the vertical mill lining in time. Once it is not available, it needs to be replaced in time, otherwise it will affect the normal production of the vertical mill.
3. The power supply voltage is unstable. Different types of vertical roller mills have different motor powers, but the vertical mill has the same requirements for the supply voltage. If the vertical mill is unstable during the production process, the vertical mill is used. A stable voltage cannot be achieved during the operation of the machine, which will affect the normal production of the vertical mill.
Combined with the above analysis, there are many factors affecting the normal production of vertical mills, and many influencing factors can be avoided, such as timely removal of the residues of the vertical mill barrel and regular maintenance of the vertical mill equipment. Timely check and replace the vertical mill lining, etc., then how to ensure the normal production of the vertical mill?
1. Normal operation of the vertical mill. Before the vertical mill is put into production, the user should carefully read the equipment operation manual, follow the correct steps, and avoid the illegal operation. This will not only extend the service life of the vertical mill, but also ensure the vertical mill. Normal production.
2. The specifications and models of the vertical mill should be consistent with the actual production requirements. Different types of vertical mills have different bearing capacities. When users purchase vertical mills, they can choose the right type of vertical mill equipment in combination with actual production requirements. If the vertical mill model has passed Small, vertical mill opportunities are overloaded, and the model size is too large, which will cause the vertical mill to idle. Therefore, users are advised to choose the right type of vertical mill.
3. The overall performance of the vertical mill is better. The overall performance of the vertical mill mentioned here mainly includes the quality of the vertical mill, the production process, the scientific and technological content, etc. The initial input cost of the vertical mill is better than that of the traditional vertical mill. Said more, but the overall income is relatively high.

What kind of equipment is used for building stone shaping? Counterattack crusher, impact crusher or VSI sand making machine? SBM is a senior manufacturer of sand making machine in the industry. Below we will introduce you to different specifications. The choice of stone shaping equipment.
Let us first understand the specifications of commonly used stone for construction. The scientific name of the stone used for construction is coarse aggregate, and its particle size is larger than 5mm, usually gravel or pebbles. Particle grading and maximum particle size: In reinforced concrete structure engineering, the maximum particle size of coarse aggregate should not exceed 1/4 of the structural size section, and should not be greater than 3/4 of the minimum clearance between steel bars. For concrete solid plates, the maximum particle size can be allowed to reach 1/3 plate thickness, but the maximum particle size must not exceed 40 mm (4 cm). For pumping concrete, the maximum particle size of the gravel should not exceed 1/3 of the diameter of the conveying pipe, and the maximum particle size of the pebbles should be no more than 1/2.5 of the diameter of the conveying pipe. That is to say, the main particle size of the stone is 5mm-40mm. VSI's new sand making machine has a very good stone shaping effect, but is it possible to use all VSI sanders to shape the stone? Let's take a closer look.
We all know that VSI's new sand making machine is a new type of stone shaping sand making machine. It is the most advanced mechanism sand equipment in the world. It is specially designed for highways, high-speed railways, high-rise buildings, municipal and hydropower dams. Concrete mixing plants provide high quality sand and gravel aggregates and are the preferred equipment for the field of artificial sand and stone shaping. So, is the VSI sand making machine suitable for stone shaping less than a centimeter? VSI's new sand making machine adopts the international advanced "stone stone" + "stone iron" principle to meet the different needs of users: artificial sand making, crushing Stone shaping, abrasive materials, etc. The sand and gravel products produced are in the form of cubes with good grain shape, reasonable gradation and adjustable fineness modulus. The maximum feed size is 30mm-60mm, which means that the 5mm-30mm stone is ideal for stone shaping with VSI sand making equipment, while the larger stone 5cm or more requires other stone shaping equipment. For larger-sized stone shaping, we recommend that you choose a counter crusher or a cone crusher for stone shaping. SBM Mining Equipment Co., Ltd. provides you with a variety of stone production equipment, sand making machines, stone shaping equipment, to provide you with a complete set of sandstone production line technology.

Quartz stone superfine grinding is a common milling equipment in mining, metallurgy, building materials, chemical industry, etc. It is mainly suitable for processing non-flammable and explosive materials with Mohs hardness below 9.3 and humidity below 6%. For example, more than 280 kinds of materials such as calcite, feldspar and limestone can be adjusted between 0.613 mm and 0.033 mm.
Regarding the working efficiency of quartz stone ultrafine mill, it is not only the equipment, no matter which equipment, it must have high production efficiency to reduce production cost and shorten the time. Low work efficiency is the natural enemy of every device. The equipment is good or bad. We mainly look at the production efficiency. Next, experts from Shibang Industrial Technology Group will explain some experiences and conclusions.
1. Improper operation
In the event of any problems in the equipment, it should be dealt with in a timely manner. It should not be seen or thought to be a minor problem. Otherwise, the mill will be subjected to a lot of pressure, which will make the production efficiency lower.
2. Specifications of processed materials
We all know that the range of quartz stone ultra-fine grinding materials is Mohs hardness below 9.3 and humidity below 6%. Therefore, when we use the mill to process materials, we should pay attention to its processing range, hardness is too large and the particle size is too Large ones cannot be directly placed into the quartz stone ultra-fine grinding process. First, the materials should be processed to the grain size suitable for the processing of the equipment. If the humidity is not reached, we must first dry it and then proceed. Processing.
3, quartz stone superfine grinding itself
Regardless of any grinding equipment, after a period of use, such as wear parts such as grinding ring grinding rolls, it is necessary to check the wear and tear of these parts on time and to maintain and replace them, because these conditions will also make the quartz stone superfine grinding. Work efficiency is reduced.

New Seminars / Is the sand machine a little leaky?
« on: July 06, 2018, 03:35:50 AM »

When the sand making machine is used for a long time, there will be some problems, such as the sanding machine hammer wear, the parts are damaged, and the equipment needs lubrication. Then there is a small amount of oil leakage in the sand making machine equipment, will it affect its normal work? How to deal with it? Below we have a detailed solution from SBM Mine senior sand making machine manufacturer.
How to solve the oil leakage of the sand making machine or the crusher? Although the machine oil leakage is a common thing, the safety hazard caused by oil leakage is something that every one of us should know. Frequent maintenance of the sand making machine equipment can greatly reduce the chance of oil leakage from the sand making machine. So what are the points that need to be repaired? Here we introduce you one by one:
a. After repairing the sand making machine, when reassembling the upper crushing roller and the shell coupling, the round nut and the coupling bolt should strictly control the tightening torque. When tightening the clamp coupling bolt, it is necessary to pay attention to In order of sequence, the diagonal bolts should be tightened first, then the intermediate bolts should be tightened, and the gap between the couplings on both sides of the facets should be uniform.
b. Maintenance and repair of sand making machine If you need to open the cover of the main and auxiliary transmission gearboxes, you must replace the rubber sealing strip and evenly apply a layer of sealing glue on the static sealing surface before reinstalling to prevent oil leakage on the sealing surface. , oil leakage.
c. The bearings of the upper and lower crushing roller translation linkages of the sand making machine are greased and lubricated. The design requires the use of No. 2 or No. 3 calcium-based grease. And the oil cup cover should be tightened once a week for normal work to inject grease.
d. The final sand making equipment is widely used in metallurgy, construction, hydropower, transportation, chemical industry, building materials industry, suitable for crushing all kinds of ore and rock with hard and medium hardness.

The type, specification and quantity of the equipment used for the sand production line should meet the quality and quantity requirements of the product. If there are a variety of sand making machine that meet the requirements, it should be determined through technical and economic comparison. For the equipment selected for the upper and lower processes, the load should be balanced. The type and specifications of the same working equipment should be as uniform as possible.
Large sand and gravel processing plants should use large-scale equipment that is suitable for the production scale, but the number of equipment for the same operation should not be less than two. The selection of the main sand making machine can generally consider the appropriate load factor, and should not consider the standby of the whole machine. When one of the following conditions is met, the equipment should be considered for standby.
1) The artificial sandstone material has high compressive strength, high hardness and strong abrasiveness.
2) Select the impact sand making machine as the medium and fine crushing equipment.
3) The number of the same operating equipment exceeds three.
The selection of crushing equipment should consider the adaptability of the equipment to the lithology of the raw materials and meet the requirements of the particle size and quantity of the feedstock. The type of screening equipment should be compatible with the processing capacity required for screening aggregates, screening efficiency, operating conditions and equipment configuration requirements. The calculation of the processing capacity of the screening equipment should take into account the fluctuation of the feed amount. The processing capacity of the multi-layer sieve should be calculated according to the control sieve layer, and the thickness of the layer at the discharge end of the screening equipment should be checked.
The type of sand making machine should be compatible with the physical properties of the sand making material, the required processing capacity, the fineness modulus of the sand, and the configuration requirements of the equipment. When selecting the medium-discharge type rod mill as the sand making equipment, the whole machine should be considered for standby, and the single processing capacity, sanding rate and rod grinding of the cobblestone sand making machine should be determined according to the industrial production test or the indoor test result. Number of machines. The belt conveyor conveys the sand material dewatered by the spiral classifier, and the upward allowable inclination angle should not exceed 12", the selected bandwidth should be increased by one level than the calculated value, and the minimum bandwidth should not be less than 650 mm.

The popularity of large vertical roller mill equipment has gradually emerged in the field of ore milling equipment. It has become a rising star in industries such as industry, metallurgy industry and chemical industry, and has become the core mechanical equipment produced by large non-metal powder production enterprises. The specially designed roll sleeve and liner grinding curve can be ground to 650 mesh at one time and to 3250 mesh by secondary powder selection. Which component parameters have an impact on the fineness of the production for vertical roller mills?
Separator parameters: the effect of separator speed on the fineness of the finished product
The main influence of the separator speed is reflected in the classification of coarse powder and fine powder by changing the wind speed. According to the working principle of the vertical roller mill, when the speed of the separator is constant, the wind speed of the feed port is larger, and the fineness of the finished material is lower.
An increase in the speed of the separator causes the disc to generate more centrifugal force, resulting in a finer material. The control of the separator speed is the main method for manual adjustment of material fineness. In order to increase the output of fine powder and let the value of raw materials play a role, it is necessary to adjust the vertical sifting rate of the vertical roller mill by structural adjustment.
Tension force parameter: the effect of tension selection on material properties
High-hardness materials, brittle materials, soft materials, and highly viscous materials require different crushing equipment for their grinding process. The tension of the vertical roller mill is derived from the hydraulic system, which is a sign of the increased level of automation in the vertical roller mill system.
The tension is adjusted according to the thickness of the material layer. If the material layer is too thin, excessive tension is a waste and abnormal vibration of the equipment. The tightening force directly affects the degree of breakage of the material, so the harder the material, the higher the tension required.
Material layer thickness adjustment: material layer thickness adjustment of fixed type equipment
The vertical roller mill uses the principle of material layer grinding. The effect of the grinding roller on the material is determined by the thickness of the layer. The fineness adjustment of the tensioning material is limited. When the material layer on the grinding disc is too thick, a large amount of coarse aggregate is generated, and the material layer is too thin, and the crushing pressure of the material is too large, which easily causes deformation of the finished material. After selecting a model of vertical roller mill, it is necessary to reasonably adjust the thickness of the layer according to the output, fineness and resource utilization efficiency, and improve the yield of the finished product.
If the equipment of the new technology such as the vertical roller mill is to gain a firm foothold in the fierce competition, it must have “extraordinary”, so that more buyers will treat each other differently instead of In the past, the advanced technology of the vertical roller mill is applied to metal ore and non-metal mines, cement production, construction and more industrial fields, so as to improve the economic efficiency of the enterprise and develop a double harvest of the circular economy. I believe that the layout of the vertical roller mill will be bigger and bigger.

New Seminars / Application of ultrafine mill for processing limestone
« on: July 03, 2018, 02:55:19 AM »

With the continuous development of China's economy, the mining of ultrafine Mill in the mine has been developed and utilized. Industrial solid waste has seriously damaged the ecological environment. Limestone is one of the commonly used materials. Limestone is produced after the ore is selected and processed. It has a high use value and will also protect the development of the ecological environment. The grinding principle of ultra-fine mill has obvious advantages in drying capacity, metal wear and simplification, etc. It has the characteristics of low noise, low dust pollution, low investment and low energy consumption, and has been widely used in cement and electric power.

Tantalum is a mineral that contains metal strontium. The use of antimony ore is mainly used to produce antimony products. The use of lanthanum as a component of other alloys can increase its hardness and strength. The process flow of Yankuang mineral processing equipment should be based on the physical and chemical properties of the type of ore, mineral composition, mineral structure, and inlaying properties as the basic conditions to be selected, and the content of valuable components and the requirements for the application of antimony metallurgy technology should also be considered. And the final economic efficiency and other factors. Sulphide antimony ore is one of the most common antimony ores. Sulphide antimony ore beneficiation is usually carried out by flotation process. South Africa is rich in antimony ore resources, and it is necessary to use various ore-dressing equipment for ore-bearing ore selection. Ore crushing and crushing equipment are naturally indispensable. The new sand making machine is also called the efficient crusher and can easily crush the antimony ore to less than 5mm. It is the best equipment for crushing fine ore.
The new type of sand making machine plays an important role in the whole process of the beneficiation ore dressing production line. The Xenon ore flotation process consists of jaw crusher, sand making machine, ball mill, classifier, magnetic separator, flotation machine, thickener and Dryer and other equipment components. The sulphide bismuth ore mined is first broken by the main jaw crusher in the ore processing equipment, and then enters a new type of sand crusher for fine crushing. After being finely crushed to a reasonable fineness, it is evenly sent to the ball mill through the lifter and feeder to be mined. The equipment ball mill grinds and grinds the ore. The ore fines milled by the ball mill enter the next process: grading. Spiral classifiers clean and classify ore mixtures based on the principle that the specific gravity of solid particles is different and the rate of precipitation in liquids is different. After washing and grading, the mineral granules after preliminary separation are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances. After the desired minerals are separated, because they contain a large amount of water, they must be initially concentrated by a thickener and then dried by a dryer to obtain dried minerals. The new sand making machine can be used to crush the ore to less than 5mm, the processing volume is large, and the fine crushing effect is good, which can greatly reduce the fine crushing of the material entering the ball mill equipment, realize more broken and less grinding, and greatly improve the grinding efficiency of the ball mill equipment. The new sand making equipment has less investment, low freight and operating costs, and is 30% more efficient than the traditional fine-brick crusher, sandblasting machine and hammer crusher, and is more energy-saving and environmentally-friendly. It is currently the most popular ore crushing equipment for the ore beneficiation production line.
What are the advantages of using a new type of sand making equipment to crush ore?
The new type of sand making machine has various types of equipment, large feed granularity, and fine material discharge, which can meet the requirements of ore fines for various ore dressing production lines. The processing capacity of 20-500t/h is suitable for different scale ore crushing production line processes. The sand making machine has high crushing efficiency and has fine crushing and coarse grinding functions. Applicable to different hardness ore crushing operations. The structure is simple, installation and maintenance are convenient, and the operating cost is low. Through the non-broken material ability, the impact of the moisture content of the material is small, the moisture content can reach 8%. Low working noise and less dust pollution. Is an ideal ore miner.

In recent years, with the continuous increase in the demand for aggregates for sand and gravel, the business of large and small stone yards and sand making machine has also become increasingly prosperous. A large amount of dust pollution will occur during the production of artificial sand aggregate, which will not only pollute the environment but also affect the lives of nearby residents. How can we minimize dust pollution and achieve green sand production? Choosing the right dust collector device is the key. Various types of dust collectors are used, such as gravity dust collectors, inertial dust collectors, centrifugal dust collectors, bag dust collectors and particle layer dust collectors, electrostatic precipitators, magnetic dust collectors, and pulse dust collectors. So what type of dust collector equipment is suitable for stone yards and sand fields? Here we have a detailed analysis for you.
Pulse bag dust collector equipment is the most widely used dust collector equipment in stone yard and sand making machine, and it is also the best equipment for dust removal. The dust collector is widely applicable to the purification of dust-containing gas and the recovery of dust materials in the food, pharmaceutical, feed, metallurgy, building materials, cement, machinery, chemical, power, and light industry industries. The new-type pulse bag filter has advanced design. After continuous improvement, it has made great progress in purifying dust-laden gas. Due to advanced ash cleaning technology and greatly improved air-blanket ratio, it has a large processing volume and small footprint. High purification efficiency, reliable work, simple structure, and small maintenance. Dust removal efficiency can reach more than 99%. It is a mature, relatively complete and efficient dust removal equipment.
The dust collector equipment adopts the upper bag-raising method. After the bag is removed when the bag is replaced, the dirty bag is put into the lower hopper of the box and removed from the manhole to improve the bag replacement operating conditions. The box body adopts airtight design with good sealing performance, excellent sealing material for inspection doors, leak detection with kerosene in the production process, and low air leakage rate. The inlet and outlet air ducts are compactly arranged and the air flow resistance is small. It is currently the preferred equipment for dust collectors in industries such as mines, stone yards, and sand blasting fields.
