1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles.
Some of these include attrition mills, ball mills and hammer mills. Great emphasis has been put in speed, throughput and power resulting in the need for evaluation of other parameters such as prediction of losses during milling process and energy efficiency especially for products produced by small to medium manufacturing companies.
Ghaghazanian et al. (2008) used grade–recovery curves of the regrind ball mill product and feed to evaluate the performance of regrinding tumbling mills. The performance of regrinding mills is satisfactory when the grade and recovery in the product is better than that of the feed.
Apr 17, 2013· performance evaluation of ball mills - Grinding Mill China. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits.
Mill Selection. The first step in mill design is to determine the power needed to produce the desired grind in the chosen ore. The most used equation, for this purpose, is the empirical Bond equation (Bond, 1960, 1961; Rowland and Kjos, 1978).

Pressure and temperature measuring system In order to understand the processes which occur during grinding with ball mills (e.g. chemical reactions, phase changes), it is helpful to record the most important thermodynamic parameters: pressure and temperature. Planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input.
