Correlating common breakage modes with impact

2020-11-1  Narrow size fractions of a Portland cement clinker and a chromite sample were used as the experimental materials. The size fractions of both samples coarser than 3.35 mm were used in the single-particle impact loading tests. Ball mill grinding tests were performed with the narrow size fractions of the clinker sample finer than 2.36 mm. 2.2.

Effect of Milling Method on Chromite Surface Composition ...

2015-4-22  The first concentrate milling to a fraction finer than 0.1 mm was performed in a metallurgical ball mill with metal milling bodies, after which the material was annealed at 1000°C for 2 h in order to remove residual stresses. Fine milling of chromite was carried out in jet and vibration mills to a maximum particle size less than 80 _m.

Charge behaviour and power consumption in ball mills ...

2001-8-1  This is a reasonable generic value, but the ball fraction is one of the charge attributes (along with ball size distribution) that can be varied by operators, so it is useful to understand its effect on mill behaviour. Fig. 13 shows the specific power draw for ball fractions varying from 0% (fully autogenous) to 100% (ball only or fully ground ...

The effect of ball size on mill performance - ScienceDirect

1976-5-1  The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...
