Ball mill is the key equipment of mineral production process, while its disadvantages include low working efficiency and high energy consumption, which influence the optimization control and energy saving of mineral processing enterprises. 1 The work efficiency is highest while the ball mill load is in the best state. However, the ball mill load is difficult to measure directly.

Disclosed herein, a classifier for classifying granular feedstock has a rotary cage rotating about a rotor axis and an airguiding system arranged around the rotary cage, wherein a classifying zone is formed between the rotary cage and the airguiding system. In the classifying zone one or more baffles are arranged such that the torque acting on the rotary cage is increased—for the same ...

In comparison with conventional ball mills, Attritors use fewer resources, including: In addition, Attritors offer the advantage of being able to take samples at any time and making formulation adjustments during high energy ball milling. Alternatively, ball mills are closed systems and do not offer these advantages.

environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions: • The grinding of coarse particles; and, • The removal of the fine particles to make room for grinding more coarse particles in the ball mill. The overall efficiency of the ball mill circuit is therefore comprised of
