Investigating the controllable factors influencing the weight loss of .

Based on these observations and the importance of wear in milling costs, this paper was aimed to investigate some of controllable factors affecting the mass loss of grinding ball. These factors were pH, solid percentage (pulp density), throughout of ball mill, rotation speed of mill, charge weight of balls and grinding time.

Grinding Media Wear Rate Calculation in Ball Mill 911 Metallurgist

Apr 29, 2017 . In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight.

How can one select ball size in ball milling and how much.

More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place. Ball size depends on initial size of charge and ranges from 10mm 150mm.
