Jaw Crusher is widely used aggregate crusher to crush all kinds of materials with a compressive strength lower than 320MPa in mining,metallurgy,public road,railway,hydropower and many other industries.

The basic structure of a jaw crusher generally includes seven parts such as driving medium,rack,the jaw plate and side rack ,flywheel,lubrication device,adjusting device and the reset spring.

The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.

This Jaw Crusher's crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw becomes bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;

When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.

PE 150x250 size :

1. Deep-chamber Crushing, High Efficiency and Energy Conservation.

The optimized deep-chamber crushing has no dead zone, so the feeding and crushing efficiency is greatly improved. It can save energy 15%-30% per machine, and the system can save energy more than 1 time.

2. Strong Bearing Capacity and High Stability

The combination of bigger heavy eccentric shaft processed by forging stock, high-manganese steel jaw plate and high-level cast steel movable jaw make the equipment has a stronger bearing capacity and higher stability.

3. Advanced Processing Technology and Long Service Life

Learn advanced manufacturing technology and make a digital analysis of every part's functioning state. It has a compact inner structure and longer service life.

4. Centralized Lubrication System and Easy Maintenance

The uniquely designed centralized lubrication system makes it much quicker in part lubrication and less in maintenance work.

5. Simple Structure, Convenient Check and Repair

Simplify the excessive components on the basic principle of compound pendulum, making the whole equipment simple, efficient, strong in crushing capability, convenient in operation and maintenance and low in operation cost.

6. Big Regulation Range of Discharging Granularity, Multi-Functions

The spacer type discharging regulation device improves its adjustment range of discharging granularity and flexibility, so it can satisfy all kind of processing requirements of customers.

7. Low Noise and Little Dust

This equipment is accordance with the national environmental protection standard. It has low noise and can be equipped with dust removing device. The working environment conforms to the environmental protection requirements totally.

How to adjust the output size of small rock crusher/small jaw crusher?

The output size of the small rock crusher /small jaw crusher is adjustable. The following article will show you how to adjust the output size of small rock crusher /small jaw crusher .

When adjusting and arranging the discharge opening of small rock crusher /small jaw crusher , unscrew the nut of tension rod which strains the part appropriately at first, unclamp spring, unclamp wedge a bolt, unclamp the wedge one, tighten the jack bolt, it push forward the toggle seat and achieve some space, then take out the shim reaching the needs of discharging opening; if add more shim, it can reduce the opening; when the discharge opening of small rock crusher / small jaw crusher reaching the needs, unscrew the jack bolt and the toggle seat with shims will be back to the frame under the weight of movable jaw. Please note that the toggle seats should not contact with frame, then tighten the bolts and firm the framework, tighten the tension rod nut appropriately and tighten up the spring, namely finish adjustment.
