The horizontal slide shoe bearing design enables much simpler foundations and reduced installation height, making installation quicker and less expensive. Our shell linings are designed to suit the task at hand. In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media.
Adjusting mill parameters: Fine-tuning mill parameters such as mill speed, ball charge, filling ratio, and grinding media size can have a substantial impact on the grinding efficiency of the mill. For example, a 10% increase in mill speed can result in up to 10% higher production rate, while optimizing the ball charge can lead to a 5-10% ...
The material is ground at a specific speed by using a specific quantity of grinding media (steel balls) for a specific period.

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.
