Phosphate ore grinding equipment
When the Phosphate ore grinding equipment is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.
Single Superphosphate (SSP)
Silica has no adverse effect other than a decrease in grade and more wear in grinding equipment. An increase in the CaO: P 2 O 5 ratio raises the sulfuric acid consumption per unit of P 2 O 5 and decreases the grade. High-chloride rocks (up to 0.5% Cl and perhaps higher) can be used without serious disadvantage since corrosion is not …
