2019-2-15 Grinding aids prevented the fine particles from report to coarse flow of the air classifier by reducing the bypass and fish hook. Thus, circulating load of the circuit decreased. Modelling studies were performed in order to evaluate this effects of grinding aids on classifier and mill model parameters.

More### Effects of Ball Size on the Grinding Behavior of Talc ...

Increasing the ball size from 0.1 mm to 2 mm increases the comminution rate and produces smaller talc particles. The delamination of (00l) layers is the main comminution behavior when using 1 mm and 2 mm balls, but both the delamination and rupture of (00l) layers occurs when using 0.1 mm balls.

2018-5-31 If the rotational speed increases for better productivity, micro cracks can occur due to strong impacts. If the rotational speed decreases to reduce the number and size of micro cracks, the productivity decreases. Therefore, it is important not only to minimize the damage caused by impacts but also to increase the mill grinding efficiency.
