Stone Crushing & Screening plant

Detailed Product Description

Stone Crushing & Screening Plant

Stone Crushing &Screening plant includes vibrating feeder,jaw crusher, impact crusher,vibrating screen,belt conveyor and electric control cabinet, etc.

The designed capacity is from 50t/h to 500t/h. To meet customers specific requiement,we also  add other equipments such as cone crusher,dust catcher on the crushing plant. *** Process of aggregate crushing plant***

Big material are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing .After first crush,the material will be transferred to impact crusher by belt conveyor for secondary crush,the crushed materials will then be transferred to vibrating screen for separating.    *** After separating,the parts that can meet standard will be transferred away as final products,while the other parts will be returned to impact crusher,thus forming a closed circuit. Size of final products can be combined and graded,according to customers specific requirement. We can also equip dust catcher system to protect enviroment.

    ***Working principle of single equipment***

***Jaw crusher**  Our jaw crusher is a high efficient and energy saving machinery which introduces successful experience of the same machine home and abroad.

   These series of jaw crushers are widely used in mine,metallurgy ,construction,roading building, railway,water conservancy and chemical industry.They feature high crushing ratio,good shape in product,simple structure,reliable performance,and low operation cost.They are ideal choice for primary crushing.  ***Operation principle of jaw crusher***

The motor drives the belt and the grooved wheel which connect the eccentric shaft.Though the movement of eccentric shaft,the movable jaw plate moves up and down.When movable jaw plate moves up,the angle between it and toggle plate will be enlarged and will be close to fixed jaw plate.Then the materials will be pressed and crushed..When movable jaw plate moves down,the angle between it and toggle plate will be reduced,movable jaw plate will moves away from fixed jaw plate,due to the tension rod and springs.At this moment,the crushed materials will be discharged at discharge opening.With moving of motor and periodical movement of movable jaw plate material will be crushed and discharged gradually,so that batch production will be reached.

    ***Impact crusher***   Impact crusher is a newly developed crusher based on advanced technologies home and abroad as well as Chinas practical mining conditions.It is widely applied in virous material crushing,railway,energy,cement,chemical industry and construction.The final size will be adjusted and crushing style is versatile,the final product takes on cubic shape with no tension and cracks,high chrome and blow bar,impact and erasion-resistant,no-key connection,high impact strengh,it processes the advantages of easy maintenance,high reliability,complete crushing ability,high productivity,little erasion in spare parts and high comprehensive efficiency.

    ***Operation principle of impact crusher***

  During the operation with the drive of motor, the rotors turn at a high speed. When materials enter the blow bar area,they are thrown to the impact plate above the motors with the strike strengh of the blow bar,then the materials are rebounded back to the blow bar for recrushing.In this way,the materials will be crushed many times in the crusher until they can meet standard and be discharged at the bottom of the machine.The size and shape of final products can be adjusted by changing the gap between the impact rack and the rotors.
