The large pieces of phosphate rock are evenly sent to the jaw crusher or mobile jaw crushing station (primary crushing) by the vibrating feeder through the silo for coarse crushing. After the coarsely crushed phosphate rock is screened by the vibrating screen, it is sent to the single-cylinder hydraulic cone crusher (middle crushing) by the ...
Moreover the transportation of crude phosphate rock with truck on an unpaved road and the dry mechanical preparation of phosphate rock (crushing, screening, and sieving) contribute to the emission of PM to air, while in Florida, a conveyor is used for the transport and a wet mechanical preparation is conducted without …
Strip screen: mostly used for pre-screening before coarse crushing and medium crushing. 2. Roller screen. The screen surface of the roller screen is composed of many parallel rollers with sieve discs staggered on them. The gap between adjacent rollers and discs is the sieve hole of this kind of sieve.
