Grinder leads the development of grinding equipment market
What are the types of grinding mill?
At present, the main grinding machine in the mining field are: Ball mill, raymond mill, vertical roller mill, ultrafine mill, hammer mill and so on.
1. Ball mill
The features of the ball mill are large crushing ratio, simple structure, standardized product series, easy replacement of easily worn parts such as lining plate, mature process and reliable operation. The ball mill can adapt to different operations, such as grinding and drying, grinding and mixing at the same time. But generally speaking, the efficiency of the ball mill is not high, the energy consumption and medium consumption are high, and the equipment is bulky and the running noise is large.
Ball mills are still widely used grinding equipment, including grid and overflow ball mills commonly used in non-metallic mineral processing. Tube mills include cement mills for grinding raw materials and cement mills for grinding various types of cement clinker. It is mainly used for grinding other materials in cement plants and related industrial departments. Short tube mills are widely used for fine grinding of non-metallic minerals such as calcite, dolomite, quartz, and zircon.
2. Raymond mill
Raymond mill has the advantages of stable performance, simple process, convenient operation, large processing capacity, adjustable product size and so on. It is widely used in the fine grinding of non-metallic minerals such as calcite, marble, limestone, talc, gypsum, hard kaolinite, clay, feldspar, barite, etc.
Mtw european trapezium grinding mill is a new upgraded product of raymond mill. It adopts bevel gear transmission, which makes the structure more compact and occupies less space; at the same time, mtw european trapezium mill is also equipped with a professional dust collector, high dust removal efficiency, low emission concentration, more conducive to meet the requirements of environmental protection.
3. Pendulum roller grinding mill
Pendulum roller grinding mill is suitable for non flammable and explosive brittle ore with mohs hardness below 7 and water content below 6%. It adopts low resistance hanging cage type separator, narrow sorting particle size range, high sorting efficiency, low system energy consumption, the same material and fineness and other conditions, lower power consumption than the vane type separator, higher efficiency.
4. Vertical roller mill
As one of the main progress of dry superfine processing technology of non-metallic mineral powder, vertical roller mill uses the relative motion of roller and disc to crush the material. It has the characteristics of concentrated process flow, small floor area, low investment, high efficiency, energy saving, environmental protection and so on.
At present, vertical roller mill has been widely used in the production and processing of white non-metallic mineral industry abroad, and has been successfully used in crushing processing of heavy calcium, barite, limestone, gypsum, pyrophyllite, kaolin, cement raw materials and clinker.
5. Ultrafine grinding mill
Ultrafine grinding mill is a high standard grinding machine designed to make up for the insufficient fineness of general grinding machine. Its fineness can reach 325-2500 mesh. The performance of the high-performance mill designed based on the new fluid theory is almost equal to that of the jet mill. At the same time, its price and cost are far lower than that of the jet mill. It can replace the jet mill and effectively solve the problems of difficult treatment and high cost of ultra-fine powder. It is recognized and loved by the industry users.
6. Hammer mill
Hammer mill is specially designed for coarse grinding. It follows part of the working principle of crusher, and makes up for the shortage of traditional mill product size range. Due to its special design, hammer mill is very popular in metallurgy, mining, chemical industry, cement, construction and other industries, and has become the core equipment for the production of coarse powder particles.
Compared with the traditional grinding mill, it has the advantages of simple working process, less land occupation, easy infrastructure construction, lower investment cost and more convenient management.
Grinding mills with low price and high-quality
For those investors who want to find a grinding mill with high quality and low price should know that get what one pays for. A high-quality grinding mill's price must higher than lower-quality's. It depends on quality. This article will show you how to choose a high-quality grinding mill in a reasonable price.
Different materials you need to process and demands of output size of materials determine what kind of grinding mill/grinding miller you should choose. In generally, the range of processing materials of grinding mills is large: Limestone, calcite, dolomite, petroleum coke, gypsum, barite, marble, talc, pulverized coal, etc.
Different kinds of grinding mill have different input size, output size and production capacity. According to different technical design, it can be divided into vertical grinding mill, raymond mill and ultrafine grinding mill.
1. Lm vertical grinding mill
Input size: 0-70mm
Output size: 80-325 mesh
Capacity: 10-340t/h
Lm vertical grinding mill integrates medium crushing, drying, grinding, classifying and other functions into a whole. It is the ideal equipment in the grinding industry.
2. Raymond mill
Input size: 0-35mm
Output size: 80-400 mesh
Capacity: 3-22t/h
Compared with the ball mill, it is a traditional choice for grinding powder, which covers a small area, is easy to adjust fineness, and the efficiency of air induction is increased from 62% to 85%.
According to continuous technical improvement, the raymond mill has been upgraded to the european trapezium grinding mill -- not only the feed size has been expanded to 0-50mm, but also the production capacity has been improved to the maximum of 50 tons. In addition, it also has low energy consumption, high efficiency and no dust.
3. Ultrafine grinding mill
Input size: 0-20mm
Output size: 2500mesh
Capacity: 25t/h
It is suitable to grind the material with middle and low hardness, moisture below 6%, and the material should be non-explosive and non-flammable.
The processing capacity of different kinds of grinding mills is different. Users should request the technical engineer of the manufacturer to issue the processing plan according to their own needs, and then choose the suitable equipment based on the comprehensive investment and market.
