Abstract A large range of iron-carbon alloys were investigated under milling conditions. The alloy systems used included AISI 1020 mild steel, high-carbon low-alloy forged steel, forged martensitic stainless steel, forged austenitic stainless steel and NiHard, 20% chromium, 27% chromium, 30% chromium white cast irons. A range of mineral slurries was also used which included a
Oct 31, 2019 In the grinding operation, the consumption of steel ball is very large, which is about 10 times more than the loss of ball mill liner. In order to make up for the loss of steel ball and keep the size of the steel ball unchanged in the ball mill machine, it is necessary to add the steel ball regularly according to a certain ratio.

Jul 28, 2015 The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result. At the other extreme, if not enough water is used, the ore will not be able to flow through the mill. The result is the ore will not be able to move into the rod load. Because there isnt enough water to carry
