Process for reducing the grain size of phosphate

26.09.1978· The mills that grind the phosphate rock consume approximately 70 kWh per ton P 2 O 5. The screened material is separated into fine and oversize grain fractions by air classifiers. The moisture content must be increased to over 50 percent for wet grinding in a ball or rod mill. The grinding process is impeded when the moisture content is under 50 percent, because the grinding parts and surfaces
