Rock phosphate mainly contain phosphate thing of fluorine and chlorine apatite, fine-grain apatite and glue phosphate rock, interfuse targets and sand, silty sand and clay and calcite and quartz, etc . Rock phosphate is mainly used to produce phosphate, also used in chemical industry such as pharmaceutical, gunpowder, etc, in the industry is widely used.
Rock phosphate grinding mill,the rock phosphate particle is not the finished products, what we need is rock phosphate powder. Usually the powder is 100-800 mesh, 1250 mesh, and 4000 mesh. In order to get them, we need use rock phosphate grinding mill to grind rock phosphate particle into powder.
Ball Rock phosphate grinding mill is the common grinding mill in rock phosphate production line. Ball Rock phosphate grinding mill is used for coarse grinding, the finished size is 0.074-0.4 mm, the capacity is larger than other rock phosphate grinding mill.
MTW medium speed trapezium mill plant is the traditonal grinding mill and popular around the world in the Rock phosphate grinding mill. It finish particles have a good uniformity of finess, with passing screen rate as high as 98%.
MTM Trapezium grinding mill is used as substitute of raymond mill for rock phosphate grinding mill. It is lower consumption, lower investment, more environment friendly, smaller occupation area.
Rock phosphate crushing process:
The whole set rock phosphate grinding mill consists of Hammer crusher, Bucket elevator, Storage hopper, Vibrating feeder, Main unit, Inverter classifier, Cyclone collector, Pulse deduster system, High pressure positive blower, Air compressors, Electrical control systems.
How does rock phosphate grinding mill work?
(1)Hammer crusher Crush the big materials into smaller ones;
(2)Bucket elevator Send smaller ones to the hopper;
(3)Vibrating feeder Send materials to the upper distribution of the turn plate (one part of main unit);
(4)Main unit When it works, numbers of rollers are moving in the ring, and the centrifugal force will force them to the edge of the turn plate and fall down.;
(5)Air compressor Inhale air from outside and bring the powder in the main unit to the classifier;
(6)Classifier The rotating impeller inside it will make the unqualified powder go back and grind again. Meanwhile, the right ones will enter powder collector along the air;
(7)Finally, the powder will come out from the discharge valve of powder collector.
