Ball Mill
The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.

Attrition Scrubbers
The attrition scrubber is also called attrition cell, attrition tank, or attrition machine. It is used to scrub the pulp with a concentration of 65-70% and to scrub the mud and fine sand on the ore. Dispersing the slime in ores to remove the impurities on the ore surface can create conditions for subsequent mineral processing and is an important part of the mineral processing production line.
