Abstract Comminution is known to be an inefficient user of energy. This makes it the largest energy consumer in many mine sites and therefore a large component of cost. One would therefore have thought that improving comminution energy efficiency would be receiving the undivided attention of the mi...

Abstract This paper describes a methodology to monitor axial mixing in an IsaMill as a function of mill feed flow rate, mill tip speed and media load. Steady state temperature measurements (profiles) along the mill length were used to quantify the degree of mixing during the comminution process. Co...

Spherical grinding media (balls) are the most widely used media for comminution of ores by grinding. One way to optimize the grinding process in a tumbling mill is associated with the development and testing of a new media shape. by modelling simulations study of the behavior of two types of grin...

Most SAG grinding operations currently use ball size between 5.5 and 6 inch maximum size, However, in most cases the use of these ball sizes hasn't been justified by a phenomenological analysis of the real effect on the grinding process, but rather by trial and error. The analysis of the influence o...
