Beneficiation ball mill has three influence factors in the grinding process with medium, including the ore properties, the structure of and the operation conditions of the machines. Use the table of contents below to navigate through the guide:
Pulp density has a large influence on the grinding efficiency. In this case, the optimum is in the region of 73.4% or 1.989 kg/l. If one goes below that, the higher dilution will 'flush' the fines out of the mill and reduce the overall residence time in the mill. This will result in a coarser grind with a slightly
