High quality PEW series Jaw primary crusher with capacity 100-450tph
PEW series Jaw primary crusher is made up of frame, eccentric shaft, grooved wheel, flywheel, moving jaw, side guard plate, toggle plate, toggle backseat, adjusting screw, returning spring, fixed jaw plate and moving jaw plate. Toggle plate is of safety function.
PEW series Jaw primary crusher Application:
PEW series Jaw primary crusher whose reduction ratio up to 4-6 and the finished products are even, can be widely used in breaking hard, medium-hard, soft ore, such as various kinds of ore, the solvent, slag, building stones, marble,etc. compression strength does not exceed 320Pa. This machine is suitable for mines,building materials,highway,railway,water conservancy and chemical industry,etc.
PEW series Jaw primary crusher Performance advantages
1, unique structure of jaw head, seal guarantee, extend working life of the bearing.
2, integral casting of the bearing base, adopt the new assembly process to perfectly match with the frame , increase the radial intensity.
3, adopting deep cavity "V" type structure, to greaten the feeding size (compared with ordinary jaw crusher) and increase the capacity.
4, adjust the structure of the discharging opening,which is convenient, quick, safe
5, tension bar protection device, more safer
6, increase the bearing capacity of the jaw head, make the machine more efficient, safe, extend the working life of the bearing and main shaft.
7, new oil road design, matched with the oil pump, more simple and efficient on the operation and maintainance.
8, unique flywheel design, effectively reduce the vibration, running more smoothly.
PEW series Jaw primary crusher Working principle
The motor-driven belt and pulley, the up and down movement of the movable jaw by the eccentric shaft when the movable jaw rises, the angle between toggle plate and moving jaw becomes larger, thus promoting the moving jaw plate close to the fixed jaw plate, its material is crushed or split pieces to achieve the purpose of crushing; When the movable jaw down, the toggle plate and moving jaw angle between the smaller, movable jaw plate trolley, spring next, to leave the fixed jaw plate, the crushed material is discharged from the crushing chamber mouth. With the continuous rotation of the motor broken motor jaw the periodic motion crushed and excreta material, to achieve mass production
