The mill charge for BWi tests supplied by Bico-Braun comes with a ball charge proposed by Deister (1987) and Bico-Baun (2016), the latter indicating it to be recommended by Bond. Table 1 . Size, mass and surface areas of proposed Bond ball mill charges.

of the procedure: grind-out, mill stoppage, mill start-up and the transition period to steady state. Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge. Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis

The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is …

The Ball Mill Grindability of ores is generally determined by the Bond standard grindability index test method. However, this test and procedure is not applicable to fine materials such as sands; the grindability of fine materials must therefore be determined by a comparative grinding method, for which a reference material of know grindability is required.
