Powder filling is challenging to measure in industrial mills. In this paper, three estimation models of powder filling are evaluated. The first is built around the crescent-shaped load; the second is empirical while the third exploits residence time

The main roles of liners are to protect the mill shell and promote effective ball motion for grinding. For this reason the liner profile is carefully selected to ensure that the productivity is maximized and due liner replacement is made when this ob

Single-particle breakage test is becoming increasingly popular, as researchers seek to understand fracture response that is purely a function of the material being tested, instead of that which is based on the performance of the comminution device be

In this work, we apply the attainable region (AR) method to laboratory data in order to optimize the milling and leaching processes of a low grade gold ore. To date, no research has been published on the application of the AR optimization technique o

In this paper, the concept of conversion used in reaction engineering is applied to ball milling. The motivation is to assess the ability of a mill to produce optimally and efficiently a narrowly-sized product. To this end, a sampling campaign was in

Sometimes it is desirable to segregate the ball load in a mill so as to allow for the possibility of larger balls dealing with coarser particles at the feed end and finer product being ground more efficiently at the discharge end. The Hardinge mill w

The attainable region analysis of batch grinding is a graphical method of establishing limits of performance of possible outcomes of any defined process. When applied to batch grinding, the results have often come into conflict with traditionally acc
