Abstract A statistical BoxBehnken design (BBD) of experiments was performed to evaluate effects of individual operating variables and their interactions on the wear rate of grinding ball mills used in the phosphate industry. The wear tests were conducted using a specially designed grinding mill. The variables examined in this study included grinding time, solution pH, rotation speed, mill ...

I claim: 1. The method of wet grinding crude phosphate rock containing clay minerals or like siliceous impurities, which comprises the steps of: introducing coarsely sized, crude phosphate rock containing clay minerals or the like into a grinding mill with at least about 20% by weight of water; introducing a substantially calciumfree alkaline additive material into the mixture of crude rock ...

The corrosion of metallic grinding media and mill liner is a very significant problem, particularly under acidic conditions as encountered in the Florida phosphate fertilizer industry. Approximately half of grinding media wear results from corrosion or oxidation dissolution of metal surfaces. An electrochemical hodic protection process based on impressed current was investigated to reduce ...
