River stone processing plant
PE Jaw Crusher
In coarse crushing unit,Jaw Crusher is mainly used for primary crushing.It's crushing ratio is big,and can make big river stones into small dust.In medium crushing process,Impact Crusher or cone crusher are used.Cone crusher is mainly used in fine crushing unit.Vibrating screen is the screening machine in stone crushing plant.If you want to get artifical sand,you must add VSI series Vertical Shaft Crusher after medium crushing process.

River Stone processing flow
1.At the plant,raw river stone will be fed into jaw crusher for primary crushing by vibrating feeder.
2.After primary crushing,the material will be transferred to secondary crushing equipment like impact crusher for further crushing.Then the screening process will begin.
3.Usually,we will equip the river stone crushing&screening plant with multi-deck vibrating screen.The vibrating screen is a key equipment to sieve the crushed stones into different grades.
4.The crushed stone meet the demands will be transported to the stockpile,the other will be sent to cone crusher or impact crusher for fineness crushing.
