Crushing equipment and recycled technics of recycled concrete aggregate

The economical production technics and advanced crushing equipment of recycled aggregate are crucial for producing and spreading recycled concrete.The main parameters of crushing equipment were ameliorated to improve the performance of recycled aggregate.These parameters included particle size of recycled aggregate,extrusion frequency,rotor's gyro frequency,rotor's eccentricity.A crushing technic made up of extrusion,heating,milling and sieving was presented based on analyzing and comparing the foreign and domestic crushing technics.And a set of crushing equipment was made according to proposed crushing technic,which can improve the performance of recycled aggregate and the reclaiming ratio of the abandoned concrete aggregate.
