Phosphate rock grinding mill
Phosphate rock grinding mill Phosphate rocks are those minerals that contain the tetrahedral coordinated phosphate anion along with the freely substituting arsenate and vanadate. Chlorine, fluorine, and hydroxide anions also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species …

Study on the Effect of Liberation Properties of Phosphate
When the fineness of grinding is − 0.074 mm with a proportion of 82.86%, the dosage of H 2 SO 4 and TP-1 reaches 12 kg/ton and 1000 g/ton, respectively. As a result, the P 2 O 5 content in the phosphate concentrate is 32.4%, while that of MgO is 1.6%, and the recovery of the concentrate is 86.28%.

Rock Grinding. Until 1973, most phosphate was ground dry in roller or ball mills. In that year, Agrico, at South Pierce, Florida, converted one of its dry mills to wet slurry grinding and proved that the plant water balance could manage the rock at a 65–68% solids slurry. Since that time, most U.S. installations have converted to wet …
