The Solution To The High Abrasion Of Grinding Steel Balls in Ball Mills

1. Change the grindability of ore

The particle size of the material fed into the ball mill is one of the reasons that affect the energy consumption of the steel balls of the ball mill. Generally, if the grindability of the input particle size is small, the ore is easy to grind, the wear of the steel balls of the ball mill is smaller, and the energy consumption is also smaller; otherwise, the on the contrary.

In actual production, if the ore that is difficult to grind or the ore requires fine grinding, it can be considered to add a certain chemical agent in the grinding process to improve the grinding effect and increase the grinding effect when the economy and site conditions allow. ore efficiency; or heat treatment of the ore to change the mechanical properties of the entire ore and reduce the hardness of the ore. Both methods can effectively reduce the energy consumption of the ball mill.

2. Reduce the feed particle size

The larger the grinding particle size of the ball mill, the greater the work done by the ball mill on the material. In order to achieve the specified grinding fineness, the workload of the ball mill is bound to increase, and subsequently, the energy consumption of the steel balls will also increase.

In order to reduce the power consumption of the ball mill, the particle size of the grinding material can be reduced, so the particle size of the crushed ore product is required to be small, that is, "more crushing and less grinding".
