European Type Jaw Crusher

European Type Jaw Crusher introduction

The European version of the jaw crusher is suitable for crushing ores, rocks, slag, etc. whose compressive strength is not higher than 280Mpa. Mainly used in metallurgy, mining, chemical industry, cement, construction, refractory materials and ceramics and other industrial sectors for medium and fine crushing of various medium-hard ores and rocks. Compared with the traditional jaw crusher, the European version of the jaw crusher pays more attention to details in design and manufacture, adopts high-strength materials, new manufacturing process, has higher structural strength, higher equipment reliability, and crushing ratio. Larger, higher output, lower comprehensive cost and other advantages. Sand and gravel aggregate and mining equipment manufacturers have provided thousands of crushing, screening, sand making, and mining solutions to customers and enterprises around the world. Today, the European version series of crushers developed and produced have become the market. The jaw crusher of concern. When considering the crushing of hard and strong abrasive materials, the European version of the jaw crusher with new crushing technology and manufacturing level should be selected.

JC European Type Jaw Crusher performance advantages

Superior cavity design

Symmetrical "V"-shaped cavity design, large inclination angle, large stroke and reasonable rotation speed of the toggle plate make the feeding particle size larger, the output higher, the particle size more uniform, and the jaw plate wear reduced.    

Design of movable jaw guard

A heavy-duty guard plate is installed above the movable jaw to avoid strong impact of materials and effectively protect the movable jaw body and its internal bearings from damage. 

Integral bearing housing

The integral cast steel bearing seat structure ensures the coordination with the frame, avoids unnecessary radial load on the bearing during the tightening process of the combined bearing seat, and makes the bearing run more smoothly.  

Convenient and quick particle size adjustment

JC series jaw crusher adopts mechanical or hydraulic discharge port adjustment device, and its double wedge adjustment method is simpler, safer and faster than the gasket adjustment, which saves downtime. 

Integrated motor installation

The integrated installation method of the motor base and the crusher frame not only saves the installation space of the jaw crusher, but also reduces the length of the V-belt. Adjustment of the tension of the V-belt, so that the service life of the V-belt is longer. 

Shock-absorbing installation design

The crusher is fixed with a special rubber shock-absorbing device, which effectively absorbs the peak vibration of the equipment and allows the vertical and longitudinal displacement of the crusher, thereby reducing the impact on the foundation.

European Type Jaw Crusher working principle

The crushing method of the European version of the jaw crusher is a curved extrusion type, and its working principle is:

The motor drives the belt and pulley, and the movable jaw swings up and down through the eccentric shaft. When the movable jaw pushes the movable jaw to move toward the fixed jaw, the material is crushed or chopped. When the movable jaw and the movable jaw move backward under the action of the eccentric shaft and the spring, the previously crushed or chopped materials are discharged from the lower discharge port of the jaw. With the continuous rotation of the motor, the mobile jaw of the crusher periodically crushes and discharges materials to achieve mass production.

Main structure: It is mainly composed of frame part, eccentric shaft rotating part, working part of crushing cavity, safety device, discharge opening adjustment device and other parts.

1. Frame part: It consists of side panels, front box components, rear box weldments, etc.

2. The rotating part of the eccentric shaft: It is mainly composed of movable jaw, eccentric shaft, bearing, bearing seat, pulley, etc. It is the main part of transmitting power.

3. The working part of the crushing chamber: It is mainly composed of fixed jaw plate, movable jaw plate, side lining plate, guard plate, etc. It is the working part of the crushed material.

4. Safety device: It is composed of toggle plate, toggle plate seat, spring, spring tie rod, etc. It is a part of the crusher that plays an insurance role under abnormal conditions.

5. Discharge port adjustment device: This device is used to adjust the size of the discharge port and control the discharge particle size. It is mainly composed of adjusting the fixed oblique block, adjusting the sliding oblique block, jacking bolt, and sliding block locking rod.
