Phosphate Rock Mining Processing
The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding.
Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities. Steps used in beneficiation were decided by the type of rock. A typical beneficiation unit for separating phosphate rock begins with wet screening to separate pebble rock that is larger than 1.43 millimeters or 14 mesh, and smaller than 6.35 mm from the balance of the rock.
The phosphate rock of various sizes are fed into the jaw crushers for size reduction. Crushing generally is carried out in one or two stages, although three-stage crushing may also be performed. Following crushing, the material is returned to the screening operation for sizing. Depending on the desired output size of the crushed stone, the raw material may be fed to one or two impact crushers, cone crushers or complete stone grinding mills in a sequence. Then these crushed stones are passed on to the rotary screen for size gradation. Material is handled through a belt conveyor to the different places of operation, for example, from jaw crusher to the rotary screen.
Phosphate rock processing equipment
Phosphate rock mining processing equipment designed and manufactured by our company is with considerable experience and integrity. Our Jaw crusher is commonly used phosphate rock crushing equipment, it works with the fixed jaw plate and mobile jaw plate compression to crush phosphate, in accordance with its moving trajectory it can be divided into simple swing , complex swing and integrated swing.
Phosphate rock impact crusher designed and manufactured by our company were commonly used after a jaw crusher. Big size phosphate rock crushed by jaw phosphate rock crusher were transported into impact crusher by vibrating feeder. This series of impact crusher is mainly used in metallurgy, mine, chemical, cement, construction, refractory materials and ceramic industries for crushing and finely various medium harden ore and rock, etc. Phosphate rock cone crusher and phosphate rock grinding mills were used in phosphate rock mining processing when necessary.
