SBM ultrafine grinding mill successfully solve the environme

Extraction of ore at a large size, the best particle dimensions are generally about 500 mm. The compounds of phosphate fines issued, for a gangue minerals and coexisting closely. Therefore, before sorting, the ore needs to be approved by crushing and grinding, in order for the complete dissociation of phosphate material.

Phosphate crushing and grinding is essential to the power of phosphate. Manufacturer of mining equipment to supply equipment SBM processing phosphate ore to interrupt completely and concentration.

Knowledge within the crushing and grinding

Crushing and grinding size being achieved, according to size and phosphate compounds employed in the tactic of mineral processing flotation broadcast rock phosphate strategy is generally adopted. Disseminated apatite crystal dimension is generally 0.5 to 0.1 mm, more granular glial DIP phosphates, typically less than 0.1 mm or less. Disseminated finer particle size, higher level of milling offers might also want to be a little more detailed, or phosphorus containing minerals and gangue minerals cannot have the separation of monomer, the direct have an effect on the standard of the chosen points. Therefore, crushing, grinding should be done prior to a election to make the operations outsourcing.

Phosphate crushing and grinding

However, used, production, and not just the fine mineral crushing survived better. Because, first of all, survived the crash ore fines, energy consumption and wear, treatment costs increase. Second, the crushing of your ore was too small, it is bound to come up with plenty of fine mud, to do more to interrupt, it's the same fine mud sub-processes to influence elections and lower the effects of selected points. Therefore, selecting the right decision before fragmentation within the size of subgrains, it is technically and economically reasonable.

Phosphate steps involved in crushing and grinding

Due to current technical and economic terms, it cannot be pulled from the ore mine by the truckloads a few points before breaking the direct election within the size requirements, so the break (or grinding) is conducted in several stages.

Crushing, grinding is often divided into the examples below phases:

coarse end of secondary crushing crushing crushing coarse grinding with the dissociation
