Grinding Balls For Ball Mill
Ball mill is a essential equipment for further grinding the material after it is crushed. It continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. Most of mines use overflow ball mill. The mineral will gradually flow to the discharge end with the rotation of the cylinder and the movement of grinding media, and finally overflow from the hollow journal of the discharge end. Therefore, compared with the SAG mill, the diameter of ball mill,the particle size and the ball size is smaller;the running speed is relatively decreased and the filling rate is higher. The grinding balls mainly impact and grind minerals by cascading, and can’t discharge unless the balls reach the specified size,which required high wear resistance. However, the attrited and deformed grinding balls have lower production efficiency and occupy the ball filling rate. If the balls still have a high hardness and cannot disappear quickly, this situation will cause energy waste and increase consumption.
After the in-depth discussion and analysis of Goldpro New Materials Co., Ltd., with the research and analysis of invalidation principle ,working condition and heat treatment process, Goldpro has developed a grinding ball for ball mill. Within the effective volume,the ball is of high hardness and better wear resistance,and the hardness is appropriately reduced at the smaller diameter, ensuring that the grinding effect and the effective filling rate in the ball mill , thereby improving the grinding efficiency , saving energy and decreasing wear rate. Practice of a large foreign mines,Goldpro’s grinding balls decreased wear rate by 15% to 20%,and has been fully approved by the mine leaders and engineers.
