PE series jaw crusher commonly known as broken jaw, through two jaw movement simulation animal, by moving the movable jaw and the fixed jaw two jaw plates of the materials in the crushing cavity between the extrusion, rolling, rolling crushing. Mainly used for compressive strength less than 320 MPa crushing, crushing operation, has the big crushing ratio, high yield, uniform product size, simple structure, reliable work, convenient operation and low cost, repair. Often used as the primary crusher is used for crushing stone production line, production line.
In the PE jaw crusher, the crushing process is accomplished through the movement of movable jaw plate and fixed jaw plate, which form the crushing cavity of jaw crusher. While working, the V-belt drives the eccentric shaft to make the movable jaw plate moves forward and backward to the fixed jaw plate. When the movable jaw plate moves close to the fixed jaw plate, the raw materials in the crushing cavity will be squeezed and crushed. When the movable jaw plate moves away from the fixed jaw plate, the crushed raw materials will fall down and be discharged from the outlet opening.
The PE jaw crusher mainly consists of the rack, bearing, operating mechanism, transmission mechanism (including eccentric connecting-rod, thrust rod, fly wheel and eccentric shaft), safety device, adjusting gear and so on.
1. Fixed body of the small jaw crusher: The main component of the fixed body is rack, which has two manufacturing engineers: carbon steel casting rack and carbon steel plate welded rack. Welded rack uses the reinforced stiffener on the basis of the original cast rack, and can achieve the same effect as casting rack through strict quality control and specific process requirements. In order to prevent the serious wear and tear of the lateral wall, crushing chamber is equipped with shield on the left and right side, which can be easily replaced.
2. Rotating body: This PE jaw crusher as a kind of double toggle jaw crusher is composed of moving jaw, eccentric shaft, bearings, pulleys and other parts, and it is the main part of the jaw crusher transmission and endurance.
a. Moving jaw of this type of double toggle jaw crusher is composed of movable jaw bracket and movable jaw plate.
b. The eccentric shaft is made up of 45 # steel can go though quenching and tempering treatment.
c. Bearing adopts an aligning spherical roller bearing, with characteristics of fine-tuning, big endurance and durability.
d. Jaw plate can be divided into mobile jaw plate and fixed jaw plate. In order to enhance the crushing effect, the surface is made up of material with high hardness and wear resistance.
3. Adjustment device: It is used to adjust the size of discharging mouth and control the discharging granularity. Zenith jaw crusher has two forms: long wedge type and plunger gasket type with convenient and flexible adjustment, can achieve stepless adjustment.
