As a major ore grinding and processing equipment, the ball mill is mainly used to grind the crushed material. Inside the ball mill, the steel ball is a key component. As a professional ore grinding machinery manufacturer, Fote will talk about some notices about the proportion of the steel balls inside the ball mill.

The steel balls are the important grinding media for the ball mill to grind materials. In the operation of the ball mill, the material can be crushed by the friction and impact between the media and the material, which is the core running part of the ball mill. In order to grind different materials with the ball mill, some principles in the proportion of steel balls should be followed, which can help increase the productivity and can lower the production cost. Today, Fote will talk about these principles with you.

The power of the electric motor of the ball mill, the energy source of the equipment, to some extent, determines the output and efficiency of the production. In the actual production, the proportion and number of the steel balls should be determined according to the power of the main electric motor. The total weight of the steel balls and the material inside the ball mill should be less than and close to the allowable value of the power of the electric power.. The load rate of the steel balls cannot be excessively high or low. If it is too low the productivity of the machine will decrease. With too high load rate, lot of power will be wasted.

The diameter of the steel ball of the ball mill should be determined according to the specification of the ball mill and the property of the material. The diameter of the smallest steel ball should be determined according to the diameter of the big steel ball and the space between the big steel balls. In general, the weight of the small steel balls accounts for 3%-5% of that of the big ones. The diameter of the smallest steel ball has a great influence on the grinding efficiency and output of the ball mill. If the work about the proportion of the steel balls inside the ball mill can be done well, the production efficiency of the whole ball mill can be increased.
