Combination of liner and wear-resistant Grinding Steel Balls
Apr 28, 2022
In the ball mill, the lining plate and the wear-resistant steel ball need to be used in cooperation with each other, and form a three-body abrasive wear with the material. Only by choosing the best liner and wear-resistant steel balls can the use of the ball mill reach the ideal level and improve the grinding efficiency.
But what should we do? It should be said that it is best to understand the concept of base hole system or base shaft system in mechanical design. For the ball mill, the lining plate has a much greater impact on the production than the wear-resistant steel ball, so it should be made of the base plate.
Therefore, when selecting the lining plate and wear-resistant steel ball, the first thing to determine is the lining plate. It is necessary to ensure that the service life of the lining plate is more than two overhaul periods, and try not to carry out maintenance. The lining plate with good reliability and high wear resistance is preferred. For example, the professional ball mill liner produced by Ningguo Kaiyuan Electric Power Wear-resistant Materials Co., Ltd. has high wear resistance, can be customized according to customer needs, and has a long service life.
The hardness of the liner and wear-resistant steel balls should be greater than HRC50. Theoretically, the hardness of the grinding medium should be greater than or equal to 80% of the hardness of the grinding material to achieve the ideal wear resistance.
The liner is well decided, and the choice of wear-resistant steel ball is also very important. As long as the service life of the lining plate guarantees two overhaul periods, it is necessary to promote the best wear resistance of wear-resistant steel balls as a priority. The principles of reducing costs, reducing labor intensity of workers, and improving operating rates should be adhered to. At present, many mines have begun to choose high-chromium alloy casting balls. Compared with traditional forged and rolled balls, high-chromium balls have better wear resistance and corrosion resistance, and are more cost-effective, making them ideal for mining and cement industries.
