The ball mill grindability test sometimes referred to as the Bond test was developed in the 1930s by the Allis ... (6 Tyler mesh) screen. Avoid over-crushing by screening, then crushing the oversize successively until it all passes the 3.36 mm screen. The choice of the 3.36 mm top size is described by Man (2002).
Size reduction at Kemi is carried out as follows: crushing in three stages with a jaw crusher and two-cone crushers, grinding in two stages with a rod mill (Ø 3.2 × 4.5 m) and a ball mill (Ø 2.7 × 3.6 m). The equipment and techniques used at Kemi to separate the chromite mineral from the gangue are two-drum separators and three dewatering ...
The specific gravity of the feed sample was found to be 3.3 g/cm 3 . A laboratory jaw crusher crushed the run of mine (ROM) ore to 20 mm size (d 80 = 12.5 mm).

Tumbling mills account major share of power consumption in mineral processing industries. In this paper, an attempt is made to minimize the power consumption in continuous grinding of chromite overburden by improving the grinding performance with different chemical additives. The additives taken are calcium chloride, sodium hexametaphosphate, …
Anoshin et al. [51] reported an increased degree of Cr 3+ leaching from chromite with a factor greater than the reduction in surface area. They attribute the phenomena to inter-granular fracturing, which substantiates the effect of GAs on the fracture behaviour. ... [66] discussed the results of the ball mill test where organosilicon …
