Overview

Henan Liming Heavy Industry Science & Technology Co. , Ltd. is the leading enterprise of rock & mineral processing equipment in the world. Since the end of the 20th century, we’ve installed more than 100, 000 crushing plants all over the world. Nowadays, PEW European type jaw crusher has already become the most popular equipment in the world without controversy. It is the first choice for hard and strong abrasion material.

Features

1. Central lubrication device is installed, so the bearing is easy to be lubricated.
2.Wedge block is installed to adjust the discharging part, which is simpler, safer and faster than the old spacer on the crusher.
3.Movable jaw assembly is made by cast steel, and it is durable.
4.Integral cast steel structure is adopted for bearing seat, which matches well with the crusher frame, and radial strength of the bearing seat is highly strengthened.
5.Crushing chamber adopts “V” structure which could make actual feed width comply with nominal one.
6. Bearing is used with larger model and higher load. Its higher load capacity and effective oil seal will lengthen the life of bearing.
7. Teeth-shape side plate makes the available area of jaw plate longer, and enhances the capacity.
8. Pressing bar and supporting bar are used to fix the jaw plate, which makes installation faster.
9. Heavy type protecting plate is installed for bearing seat, in order to avoid the damage of bearing seat. 10. Supporting bar under jaw crusher protects movable haw and frame from being worn down.

Working Principle

The crushing method of European type jaw crusher is dynamic squeeze. The working principle is: 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.
