The preflotation treatment generally begins at the rodmill. A cleaning agent such as sodium silicofluoride, trisodium phosphate, or sodium sulphide with sodium hydroxide is added with the fine crushed ore to the rod mill and grinding is accomplished with a dilute pulp (2535% solids). A Spiral Screen on the rod mill discharge eliminates tramp ...

Phosphate Rock Grinding Plant. Primary size reduction generally is accomplished by crushers and grinding mills. Some classification of the primary crushed rock may be necessary before secondary grinding (rod milling) takes place. The ground material then passes through hydrocyclones that are oriented in a 3stage countercurrent arrangement.
