Stone crushing equipment consists of jaw crusher, impact crusher, cone crusher, fine crusher, roll crusher, hammer crusher, mobile crushing station, etc. Process of rock crushing line: Big size stones are transferred to primary crusher through Vibrating Feeder from hopper for first crushing, then the crushed materials are transferred to Impact Crusher through Belt Conveyor for secondary crushing. The crushed materials will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and that with unsuitable size will be transferred to the Impact Crusher for re-crushing. This forms closed circuit manifold cycles. The sizes of final products will be graded and separated according to customers' requirements, and the deduster will be attached for the sake of environment protection. Characteristics of stone crushing line: They are widely used in the mine, metallurgy, building materials, highway, railway, water irrigation and chemical industry. They have the features: Big crushing ratio, even granularity, simple structure, reliable working condition, convenient repair and economical operation. This factory produces various types of rock crushing and screening device, including coarse crushing Jaw type, fine crushing Jaw type, cone type, impact type breaker and vibration feeding machine, reciprocating sieve, belt conveyor, they have the characteristics of large crushing ratio, granularity is even, advanced structure, reliable work, excellent quality., the use service is convenient, low operation expenses, etc. Deeply welcomed by domestic and foreign customers.
