What are the ways to prolong the service life of the rubber liner of the ball mill?

Because there are many types of raw materials for grinding, and the hardness of raw materials is also different, common grinding raw materials include: various mine raw materials
Some people reflect that the service life of the rubber lining of the ball mill is too short, so I will explain to you why the service life is relatively short and how to prolong the service life of the rubber lining of the ball mill:
1. The influence of grinding medium
Because there are many types of raw materials for grinding, and the hardness of raw materials is also different, common grinding raw materials include: various mine raw materials, such as copper ore, manganese ore, etc.; various non-metallic minerals, such as limestone, granite, etc.; and power industry The hardness of the coal and medium used is an important reason for the wear and failure of the lining plate. The higher the hardness of the ore, the shorter the service life of the lining plate.
2. The impact of some common mistakes during homework
There are generally two common mistakes: one is that the feeding is uneven, sometimes the feeding block is large, and sometimes the machine runs empty, causing the steel ball to directly rub against the cylinder and the liner, and both of them are worn. The crushing of the liner and the steel ball will greatly increase the chance of wear and cause great damage to the liner. Compensatory rest, for example, bolts are loose and dropped, individual liners fall off, etc. If they are not replaced in time, the defect will not be caused by the current small section, but will spread to the entire fuselage, affecting the liner and cylinder cause a lot of damage.
3. The influence of the material of the rubber liner of the ball mill
According to the physical properties of the liner material, it mainly depends on the hardness and impact resistance. The higher the hardness of the material, the better the wear resistance, which may reach a proportional relationship, so that the steel balls will fall like a waterfall during the operation of the ball mill. , to produce an impact force on the material and the liner, the size of the impact force depends on the size of the block, the diameter of the steel ball and the diameter of the mill cylinder.
Fourth, the impact of ball mill manufacturing and installation technology
The incompatibility between the liner and the wall of the cylinder and the defects of its own casting, the mechanical properties. The chemical composition does not meet the qualified requirements, etc. These are the direct factors that affect the normal operation of the ball mill.
