Mining Machine Sthone Crusher Ce Approval Jaw Crusher

Jaw crusher is be widely applied in metallurgic, mining, chemical, cement, construction, refractory and ceramics industries, for the medium or fine crushing of various medium hard rocks and minerals, etc. The stone crusher is capable to crush mineral ores, rocks, and slag with crush strength less than 280Mpa. And size of materials fed in the stone jaw crusher should be equal or smaller than the maximum feeding size described in the following technical data.


 
In the crushing line, the stone jaw crusher is usually used in the primary crushing. The stone crushed by the jaw crusher will be delivered to the impact crusher by belt conveyor. After crushed by the impact crusher, the crushed stone will be delivered to the vibrating screen. The finished product will be screened out. The stone bigger than the required size will be returned to the impact crusher for recrushing. It's a closed circuit.

jaw crusher is mainly composed with machine body, eccentric axis, connection rod, jaw plate and regulating mechanism. V belt is used to transfer the momentum to the connection rod to drive the moveable jaw plate to crush materials. The size of discharge material can be adjusted by regulating adjustment nut and screw, top plate base and sliding seat.


 
jaw crusher body is made of cast iron; the front wall is installed with fixed jaw plate; the rear wall is installed with spring and lockup nut; the two sides are installed with lining plate and rectangular iron bar; the top is installed with two sliding bearing blocks used to support the eccentric axis. The eccentric axis is supported in the sliding bearing trial hole and the middle is connected by two roll bearing connection rods. Moveable jaw plate is installed on top of connection rod and the under part is connected with the regulating mechanism through bracket plate.

jaw crusher motor drives the movable jaw up and down through eccentric shaft. The angle between toggle plate and movable jaw increases when movable jaw moves up. So the movable jaw will be closed to the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and movable jaw decreases when movable jaw moves down, movable jaw moves away from fixed jaw under the movement of draw rod and spring, the material will be discharged from the discharging opening. This process is repeated. The movable jaw will crush and discharge the stuff periodically to achieve mass production.



Jaw Crusher are available: assembled frame and welded frame.
PE series jaw crusher is usually used as primary or secondary crusher in quarry production lines. PE Jaw Crusher, equipped with the most advanced crushing technology, is the top choice of crushing multihard, corrosive materials. Compared with the traditional secondary jaw crushers, which cannot provide bulk production and wear resistance at crushing stones for constructions of highways, railways and airport runways, which mostly are hard rocks like basalt at the size of 3~7cm, PE jaw crusher has unparalleled superiority on service life, maintenance rate, failure rate and lower cost of supporting facilities like cone crusher shaping machine.



jaw crusher mainly includes base, fixed jaw, swing jaw, eccentric shaft, fixed jaw tooth plate and moving jaw tooth plate that fixed on the moving jaw by connecting rod bolt. There are side shields on both sides of swing and fixed jaw tooth plate, the upper end of the moving jaw sets in the eccentric shaft with a bearing chamber between them, the moving jaw tooth plate is 80~250mm higher than the fixed jaw tooth plate.



Features:
 1. Assembled PE Jaw Crusher: easy installation, good balance, with cushion and stopper.
 2. Integrated motor: crusher motor frame, the motor frame and crusher-one structure,reducing installation space and belt length, increasing the life of belt because of the simultaneous movement of crusher and motor.
 3. The finite element analysis techniques: with the aid of the industry's most professional mechanical design software, the whole design process and the processing technology has been efficiently controlled to gain higher yields and efficiency,meanwhile, material has been fully used to make less weight of crushers.
 4. Bearing: containing 4 same bigger bearings, jaw crusher has longer service life.
 5. Bigger output: new kinematics design and suitable rotation rate make the movable jaw can get more impact. With the symmetrical shaped structure crushing chamber,the crusher can get higher output.
 6. Insert adjustment: at mechanization adjustment, the crusher can be regulated whether at work or shutdown. When turned into hydraulic adjustment, automatic control is achieved.
