Why the ball to powder ratio (BPR) is insufficient for ...
Jun 15, 2014 Magnesium hydride powder (ABCR Germany, 98%) was milled in a Fritsh P7 premiumline planetary ball mill. The milling process was performed with different parameters, including the ball and powder mass, total milling time and number of cycles, but the ball to powder ratio (BPR) was kept constant in all cases. The resulting BPR was 6.2.

How to choose the ball loading and loading ratio of ball mill?
When the ball mill is used for pulverizing material, the ball milling ratio of the following steel balls is the highest: In production, the two-stage ratio and the multi-stage ratio are more common. Generally, the multi-stage ratio follows the principle of “less at both ends and more in the middle”.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
Aug 02, 2013 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

The working principle of ball mill - Meetyou Carbide
May 22, 2019 The larger the ball to material ratio, the higher the grinding efficiency. But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties (Figure 8-2). The ball ratio is usually selected from 2:1 to 5:1.
