Advantages of vertical mill compared with ball mill in cement production line

2016-05-30

Advantages of vertical mill compared with ball mill in cement production line is provided by SBM,And it’s widely used in many practical fields. SBM is a professional production Stone grinding plant(Advantages of Vertical Roller Mill compared with ball mill in cement production line) manufacturers,We have a wealth of experience and the most advanced technology. If you need any crushing, grinding, process equipment, you can contact us by free online consultation or leave us a message by the following form.
SBM LUM Vertical Roller Mill is integrated with tertiary crushing, drying, grinding, powder separation and conveying and is the best choice for processing slag and cement. Then compared with ball mill, what are the advantages of vertical mill.
1. High powder grinding efficiency.
Vertical mill adopts material bed grinding principle to grind the materials, so that the grinding efficiency is improved by 30% than that of ball mill.
2. The technical process is simple and saves infrastructure investment.
Vertical mill has a separating machine, and uses hot smoke to convey the materials, so that no powder separating machine and elevating machine are needed. The gas containing dust will directly go into the powder collector for collection, so that the grinding system is simple, the failure rate is low, running rate is high.
3. Strong drying capacity.
Vertical mill adopts hot air to convey materials, and when grinding materials with high water content, the inlet air temperature can be controlled to make sure that the products will reach the final water content. Vertical mill can dry the materials with the water content 12-15%.
4. Small abrasion of the metal.
In the running process of Vertical Roller Mill, no metal materials directly contact with each other, so that the abrasion is small, and the unit abrasion consumption for limestone is generally 4-6 g/t.
5. Low noise and little powder dust.
In the working process of vertical mill, the grinding sound is soft, often about 80 db. The grinding roll and the grinding disk does not contact with each other. Vertical mill adopts integrated sealing, and the system works under negative pressure, so the powder dust is little.
6. Even final products.
The qualified products inside the vertical mill can be timely discharged, thus avoiding over grinding and the product granularity is even.
Grinding is an important technical link in the production of cement, as it not only determines the unit electricity consumption of cement production, but has great influences on the performance of cement. For a long time, cement grinding is completed inside ball mill as it has the features of simple structure, reliable operation, convenient maintenance and management, strong adaptability for the materials, continuous production, big production capacity, big grinding ratio and easy control of the fineness of the final products. However, the effective energy availability is only 2%-5%, and the majority of the rest energy is changed into heat energy, and the economic benefits are not optimal. In recent years, traditional Vertical Roller Mill is improved and updated, and new type of powder separation closed-circuit system is adopted and the cement grinding technology is developing rapidly. Especially the application of vertical mill greatly reduces the energy consumption of grinding slag cement and improves the grinding efficiency.

Analyze the Import and Export Situation of Mining Machinery Equipment

2016-05-27

With the healthy development of the domestic economy, mining machinery equipment market is more popular. The output value of Talcum powder processing plant can increase about ten billion average annual; the market share in domestic is also higher and higher.
For a long period of time, due to the domestic producers have not mastered the technology to design and manufacture large-scale and high-end Iron Ore Processing Plant, the market share of foreign equipment in the domestic market is relatively high.
However, with the more and more emphasis on research and investment in technology in the past few years, the quality of China’s mining machinery products has obvious changes. There have emerged a large number of large scaled and advanced products with the independent intellectual property rights which greatly narrow the technological gap with the advanced countries. With the accumulated experiences and the support of the national policy, we can compete with the advanced country in the international trade by virtue of the price, service and the quality. Because of the above reasons, China’s mining machinery products have appeared gratifying situation of trade surplus. The dependence of import equipment of China mBlack powder magnetic separators market is more and more small.
In the further development process, the general trend of mining machinery industry is that the exports will further expand, while imports will gradually decrease, the narrowing trend of import and export deficit will become increasingly evident. But the domestic mining machinery should continuously research the new technology. If the Low Intensity Magnetic Separator wants to narrow the import and export gap, they must do technical innovation, improve the mineral utilization, and change high pollution and high consumption situation of mineral processing. Only by realizing the qualitative change from the quantitative change can the mining machinery industry remain invincible.

Complete Introduction to the Flotation Separation Process

2016-05-19

Flotation is a Hematite ore processing plant done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic (wetted) particles are left behind in the slurry.
Flotation is a physical-chemical process that uses the difference in the surface properties of the wanted and unwanted particles. It involves a three-phase interaction between solid, liquid and air. In general, we need to use the agents in the Chalk Powder Making Machine. Flotation surfactants are the surface-active agents, which adsorb on the mineral surface and change the mineral characteristics. This can be classified into different groups:
1. Collectors: These are the chemicals that adsorb on the mineral surface and make it hydrophobic.
2. Activators: If the mineral surface doesn’t adsorb a collector, special reagents are added to the system, which allow the collector to bind the mineral surface. An activator normally works by adsorbing onto the Talcum powder processing plant, thereby providing sites for the adsorption of the collector species.
3. Depressants: The purpose of depressants is to inhibit or retard the flotation of a desired type of particle. It either inhibits the collector molecule from adsorbing onto the particle surface or to mask the adsorbed collector species from the bulk solution so that the particle does not display a hydrophobic property.
4. Dispersants: These are used to prevent fine particle aggregation. It gets adsorbed on the surface and thus increasing the strong columbic repulsion forces and preventing particles to aggregate.

Application Analysis of Stirred Mill in Ore Beneficiation Production Line

2016-05-18

With the dilution and hybridization of mineral resources and the reduction of the separating granularity, the ores need to be ground to finer to improve the ore beneficiation index and the product quality. In the ore beneficiation industry, kustelite, copper concentrate and lead zinc ore need to be ground to very fine particles in which the quantity of -400 Mesh products accounts for over 95%, some minerals even need to be ground to below -10um. As a superfine crushing machine, Raymond Mill can realize this goal and it has achieved good effect in the production practice.
Tower-type stirred mill is a highly-efficient and energy-saving superfine grinding machine which has the outstanding advantages of high LUM Vertical Roller Mill, energy conservancy, low noise and investment. China begin to research and develop this type of grinding mill in the early stage of the 1980s, and after many times of industrial experiments, the results show that this equipment can gain good comprehensive benefits when replacing common Vertical Roller Mill.
(1) Application in Gold Ore Beneficiation
Gold is covered by pyrite and the gold ore existing with the state of solid solution is one type that is difficult to extract. The key to gold extraction is to break the coverage of pyrite to fully separate the gold. Superfine ore grinding can be used as pre-processing to reduce the cost of pressure oxidation and bacterial oxidation.
(2) Application in Molybdenum Ore Beneficiation
The molybdenum market in our company has long been low and the main reason lies in the product quality. Traditional ore beneficiation technology is multi-stage grinding and multi-stage dressing, and the ore grinding equipment mainly uses traditional Vertical roller mill operation, which can easily produce argillization when the molybdenum ore is doing monomer separation and lead to over grinding, and this will bring negative influence to the flotation separation. The grade of the molybdenum concentrate produced by ball mill can only reach as high as 51%, and it is difficult to improve its grade. However, using superfine stirred mill makes it possible and the quantity of the ground ores whose fineness is -325 Mesh accounts for 80%.

Comparing the Application and Performance between the Ball Mill and Rod Mill

2016-05-17

1. The performance of rod mill
The rod mill is named by the steel bars which are loaded in the cylinder body as the grinding body. Ball Mill For Gold also adopts the wet overflow type. It is available as an open circuit ore grinding and widely used in the artificial sand, dressing plant, chemical plants and power sector.
The grain characteristic of the rod mill product is related to the mineral condition. When the steel bars combating the ore, it becomes coarse ore firstly and then becomes the small sized ore grain which reduces the condition of over-pulverization. When the rods clamping the coarse grain turn upward along the liner, the fine grain will discharge from the space between the stick. It is also conducive to broken the coarse grain and make the coarse grain in the striking place. Therefore, the rod mill product is more uniform and the over smash is lighter.
The selection of Rod Mill or rod mill in the process should depend on the specific circumstances.
2. The grinding process of rod mill and ball mill
The function of the rod mill and grinding equipment are basically the same, but there are some differences between the grinding process and grinding application.
Rod mill adopts the advanced controllable output materials technology and equips with suitable grinding body according to the grinding materials of the actual users. It changed the surface contact of the traditional ball mill into line contact which makes the feed size is more even and the output. It is suitable for different hardness of the ore. We can change the particle size with simple adjustment. The control device and the screening device can ensure the quality of the finished product.
The most important equipment in the aerated concrete equipment is the ball mill. It is used for the grinding of lime, gypsum, slag and other materials. Materials only after grinding can meet the required fineness and then fully mixed to make the finished products meet the strength requirement. Vertical roller mill operation is the important progress in the production of aerated concrete. The power consumption in the grinding process is large. Generally speaking, the ball mill is the largest motor capacity equipment in the aerated concrete plant.

Analysis Of Abrasion Situation Of The Steel Ball Of Ball Mill

2016-05-10

A grinding mill is a unit operation designed to break solid materials into smaller pieces. There are many types of grinding mill, such as Ball Mill, Raymond mill, MTM trapezium grinding machine, high pressure suspension grinding mill and so on. As an ideal grinding mill for secondary crushing, ball mill is an efficient pulverizer machine for fine powder grinding. Ball Mill is widely used in many fields. This durable ball mill can grind many kinds of mine and other materials, such as the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.
The abrasion of the steel ball of ball mill is an irreversible process of hysics to machine?and hysics to chemical?that happens on the surface of the solids. The abrasion of the steel ball is mainly divided into mechanical abrasion and corrosive wear these two types, and the former is caused by impact, grinding, friction and fatigue, and the latter is caused by the effects of ion and chemical agents in the rock slurry.
Mechanical abrasion: The factors that influence the mechanical abrasion include the material quality and weight of the steel ball, the size and working condition of the Ball Mill, the granularity distribution of materials feeding and final products, the hardness of the rocks and the temperature of the rock slurry. Generally speaking, increasing the metal content in the steel ball will decrease the mechanical abrasion, for example, the stainless steel ball is more durable than the common carbon steel ball. The impact and grinding occurring between the steel ball and steel ball, steel ball and rock materials and steel and the lining board will be consumed with the transfer of the energy. Krushcho assumes that only about 10% to 20% of the energy consumed by the impact force is used for rock crushing. The rest energy is consumed in such aspects that lead to the abrasion and damage of the steel ball such as plastic deformation of the Grinding Mill, metal cutting and move, transformation of the organizational structure of the steel ball, Increase of the surface residual stress, recrystallization of subsurface stratum metal.
The abrasion speed influenced by impacting and grinding is mainly determined by the impacting energy, which are the weight of the steel ball and the size of the grinding machine. In the moment of impacting touch, the touching point will produce highly concentrated stress, which will cause the plastic deformation of the surface of the steel ball, for this reason, the steel ball surface will form cracks with different shape and depth. In the rock grinding process, after the steel ball suffers several times of impacting and Ball Mill, the cracks will constantly deepen and widen, and finally part of the fragment will break away from the ball.
SBM Mining Machinery Co., Ltd is a large-sized ball mill manufacturer, and our ball mill has many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price. Welcome all new and old customers come to our company for inspection and purchase.
