In the mining equipment, there are many types of mill models, including different models and structural principles, respectively, for different user needs, production, etc., mainly including Raymond mill equipment, limestone mill, ultra-fine milling Machines, centrifugal mills, air mills, etc., for different materials in different fields, the main industry sectors are mining, metallurgy, chemicals, building materials, electricity, ceramics, etc., and the continuous sales of their equipment with the development of the industry It is also constantly increasing, and the level of equipment is constantly improving. Raymond mills are getting better and better in the market these years. It can be seen that the mill equipment has an important position in China's economic development. Increased productivity while driving social progress and development.
The important role of Raymond Mill in various ore industries is undoubted. The mill equipment combines with the current technical level, adopts a new internal structure, and has the effect that other crushing and grinding equipment can't. The work efficiency is high and the land is occupied. The area is small, and it is higher than other similar equipment in terms of cost performance. From the user's point of view, we strive to achieve greater user benefits and material savings.
The lining of stone grinding equipment is divided into fixed lining and movable lining. It belongs to the vulnerable working parts of the mill equipment. The wear form of the lining is different according to the material and the wear condition is different. The general stone milling equipment liner is made of cast steel and manganese steel, and in some cases is made of chrome steel. If the soft ore is ground, the liner is used to protect the cylinder from the direct impact and friction of the abrasive body and material. At the same time, different types of liner can be used to adjust the movement state of the grinding body to enhance the grinding body. The pulverizing effect of the material helps to improve the grinding efficiency of the mill, increase the output, and reduce the metal consumption.
In large stone milling equipment, the lining is divided into several sections according to the width and length. The linings can also be exchanged with each other, so that the service life of the lining can be increased several times. The service life of the liner depends on the characteristics of the ore and the quality of the material from which the liner is made. Assuming that the stone milling equipment grinds quartz ore, the liner made of manganese steel can be used for an average of 3-6 months. Its general life span is 1-2 months to 2-3 years. The consumption of manganese steel is from 0.0045 to 0.028 kg per 1 ton of ore. The consumption of chilled cast iron liners for each ore is from 0.01 to 0.1 kg, with an average of 0.05 kg.
Liners of different stone milling equipment are available in a variety of shapes: finer and brittle rocks, and liners using plain weaves are reasonable. The coarse crushing is corrugated or the toothed surface, and the projection of one of the linings should coincide with the corresponding recess of the other lining.
