Artificial gravel bone_limestone material production process to guide

 Aggregate Crushing,Aggregate Machine .Three - stage crushing limestone raw materials to produce artificial aggregate , coarse broken jaw crusher , processing of particle size less than 200mm ; in broken uses two impact crusher processing particle size less than 80mm ; crushing vertical crusher, fineness less than 40mm , to weed out the wool mixed a small amount of roots and soil debris in the primary crushing plant is equipped with vibrating feeder for screening . Order to meet the use of sand for sand taken from the two screening of 30% stone and 50% of the stone , especially to increase the vertical crusher , at the same time in order to improve the stone 's graded gravel and plastic to improve the gradation of stone sand production quality has improved .

Primary crushing plant : raw material greater than 80mm of raw materials to feed the jaw crusher consists of vibrating feeder , processing the mixture to 200mm ; not more than 80mm of raw materials to reject material sieve . The shaker will be greater than 20mm of material separation of the material less than 20mm belt conveyor transport . Primary crushing plant can accept raw material particle size of less than 750mm , pretty stone larger than 750mm will be the second solution of the stone to use ;

Broken in a screening workshop : shaker , the separation of greater than 80mm and 80 - 40mm boulder into the finished product stockpiles by belt conveyor , and more than 80mm into the crusher crushed , broken back to a screening workshop grade, less than 40mm the mixture into two screening workshop to continue screening at lower levels ;

Sand two screening workshop : vibration sieve separation of 20- 40mm ,5 - 20mm of coarse particles less than 5mm of sand and sand , stone , stone and sand belt machine sent directly to the finished product stockpiles for sand stone , stone and sand in the coarse particles fed by the belt conveyor for crushing and shaping .
