Ball mill is the key equipment for grinding after the crushing process in the beneficiation plant, it is used to grind kinds of materials such as copper ore, gold ore, magnetite ore, quartz, lead zinc ore and other materials into fine powder 20-75micrometer.
Grinding medium of ball mill:
     The grinding medium is essential for the ball mill, and the consumption is very large. It was all spherical, and then the casting and baseball media appeared. The diameter of the ball medium is about 15-125mm, and the diameter of the casting section is about 8-30mm, and the length is about 8-40mm. Steel balls can be made by forging, rolling and casting. Steel ball is divided into carbon steel ball and alloy steel ball. According to the content of carbon and alloy elements, there are high, medium and low carbon steel balls and high, medium and low alloy steel balls. The ball is divided into ordinary cast iron, alloy cast iron and natural multi element low alloy cast iron ball. After the steel ball is made, it can be further treated by heat treatment to increase its wear resistance. Generally, different size and different types of grinding balls should be selected according to various specific situations, so as to achieve the best grinding effect and get the best economic benefits.
