Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

DOVE Ball Mills are highly efficient size reduction machines, designed for grinding applications, where fine material is required. Applicable for wet and dry grinding applications within the following branches of industries: Mining, Hard Rock Gold Mining Application, as well as Base Metals, Ferrous Metals.
P a p e r Introduction The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin uously optimize mill operation, it is vital to
The mill length is: L = 1.54 x 5.33 = 8.21 m. These dimensions are fairly close to those predicted from the Bond method . The dimensions estimated refer to ball mills operating under wet grinding conditions. These ballmills are of overflow type .
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of ferrous and non ferrous metals. The ball mill can grind ores and other materials either wet or dry.
The Ball Mill Abrasion test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications. In this paper the BMA test
