Introduction

PEW Series European Jaw Crushers Introduction


Compared with traditional jaw crusher, PEW series european type  jaw crushers pays more attention on details in the process of design and manufacture. It uses high-strength materials, advanced manufacturing technology, which contributes to the stronger structure, higher reliability, larger crushing ratio, higher productivity, lower cost. It is widely used in mining, metallurgy, construction, highway, railroad, and water conservancy, etc.


Stone Jaw Crusher Structure

Rock Jaw Crusher Working Principle


The electromotor drives the belt and pulley to make the movable jaw move back and forth, up and down through the eccentric shaft. The raw material is squashed or split when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and movable jaw plate turn back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically.



Stone Crushers Features & Advantages


Overall Bearing Support

Overall cast steel bearing housing fully compatible with the frame, avoiding the radical load on the bearing during the fastening process.


Optimized Cavity Structure

Symmetrical V formed design, toggle of large obliquity, long stroke, reasonable rotor speed, allow larger materiel block in feeding, higher productivity, homogeneous output granule, less attrition for jaw plate.


The whole set of heavy movable jaw plate is durable

The whole set of heavy movable jaw plate integrates forged heavy eccentric shaft, high quality bearing of heavy loading, the design of movable jaw plate optimized by finite element analysis. These features assure the stroke resistance and stability. Labyrinth seal and centralized lubricating system prevent the greese of bearing not to be contaminated, and assure the easy lubrication which results in longer function and more stability.


One piece cast of bearing seat

One piece cast of bearing seat assures good match with frame, and avoids unnecessary radio direction pression for bearing in fastening process which occurs usually to composed bearing seat. Therefore, bearing can function more stably.


Fast and easy adjustment of output granularity

PEW series jaw crusher adopt mechanic or hydraulic device to adjust discharge opening. Compared with shim, adjustment by double block is simpler, saver, faster, and reduces downtime.


Installation integrating motor & crusher

Integrative installation of motor chassis and crusher frame not only saves installation space of jaw crusher but also reduces the length of Vee belt. Thanks to synchronous movement of crusher frame, motor chassis and motor. Adjustable motor chassis can realize the adjustment of Vee-belt's tensile force to make the Vee-belt more durable.


Shock absorber installation

The crusher is fixed by the device of special rubber shock absorber, which absorbs effectively the its vibration at the peak point and meanwhile, allows crusher to displace in vertical and horizontal direction. In this way, the shock to foundation would be reduced.
