Development Trend of Rubber Lining
Rubber liner is widely used in ball mill as a supporting product. The main function of liner is to protect the inner barrel of ball mill from the impact friction of mixture in the barrel. So the working efficiency of ball mill also depends on the quality of liner. Now the market rubber liner has the trend of replacing steel liner. Let's know the specific situation with the small edition.
In recent years, the rubber liner of ball mill appearing in the market has gradually shown its advantages along with the rising utilization rate. In addition, the round square liner and magnetic liner are also new materials. Compared with these new mill liners, high manganese steel still occupies the leading position at present. Its advantage is that its toughness is very good, but at the same time of hardening, liner expansion may occur. The problems of expansion and deformation have the defects of high steel consumption, high cost and low efficiency. These problems can be well solved by rubber liner of ball mill. It is believed that in the near future, rubber liner will replace high manganese steel as the mainstream of mill liner.
It is worth mentioning that in metal mines, because of the weak abrasion force of steel balls and rubber lining, some people worry that rubber lining will reduce the grinding efficiency. The answer is No. This is because the contact area between the steel ball and the liner is much smaller than that between the steel ball and the steel ball. The former only accounts for 1%~2%, so the influence of the rubber lining on the grinding force is negligible. Moreover, because the rubber lining plate is thinner than the steel manganese lining plate, the effective volume of the mill is increased, the lifting height of the steel ball is increased, and the impact force of the steel ball is enhanced, which will be beneficial to the improvement of the mill capacity.
The above is about the development trend of rubber liner. Do you understand it? Above can be seen that the development prospects of domestic rubber liner can be described as a great one. Let's work together to contribute to the development of the industry.
