improvement on ball mills

Consult a professional engineer for details. The optimized grinding media can improve the ball mill efficiency by about 30%. The lining plate is another part that direct contact with the material. The liner made of ordinary material is too thick, which will reduce the effective volume of the ball mill cylinder.

As a part of direct contact with the material, grinding media is an important factor to improve the ball mill grinding efficiency. The efficiency of the ball mill can be improved mainly from two aspects: the proportion of different sized grinding media and timely media refilling.

The researches show that the ball mill efficiency is also related to the feeding size. The larger the feed size, the longer the time needed to grind the material to needed fineness, the more power consumption, and the lower the efficiency. The crushing efficiency is higher than the grinding efficiency, so a crusher can be equipped before grinding.

High manganese steel is very wear-resistant, and the surface hardness of the liner made by it can reach HV500. Such material can increase the liner wear resistance, and the effective volume of the cylinder to improve the ball mill efficiency. Besides, the shape of the liner can affect the ball mill efficiency.

To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly. In order to reduce the feed size of ore, the particle size of crushing product must be small, that is, "more crushing and less grinding".

Controlling material feeding refers to feeding size and feeding speed. To control the feed size, “more crushing and less grinding” is a good principle. Feeding speed means to send the material into the ball mill cylinder at a moderate speed. The researches show that the ball mill efficiency is also related to the feeding size.
