Jaw crusher is widely used in mining, metallurgical industry, building material, highway, railway, water conservancy and chemical industries. Various materials with compressive resistance less than 350 Mpa can be crushed.
In the process of crushing huge rocks into small rocks, the first crusher is usually the “main” crusher. The longest and most robust crusher is the jaw crusher. It reduces large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw – a movable jaw and a static jaw. They simulate the movement of the animal’s jaws to complete the material crushing operation. The jaw crusher is widely used in mining, building materials, chemical industry, metallurgy and other industries. It can perform coarse and medium crushing operations on various ores, rocks and other materials with a compressive strength of not more than 320MPa. Due to the jaw crusher’s ability to crush all kinds of materials of any hardness, low-cost operation and easy maintenance, it is the most widely use in the current crusher series and it is mainly used as primary crusher.
According to the width of the feed opening, a jaw crusher can be divided into three types: large, medium and small.
The width of the feed port is larger than 600MM, which is a large jaw crusher.
Medium-sized jaw crusher with a width of 300-600MM for the feed opening,
The width of the feed port is less than 300MM is a small crusher.
We have primary(Rough break) and secondary(Finely break) types of jaw crusher.
Roughly broken is PE model, it has the features of large input and large output.
Fine breaking is PEX model, it has the features of small input and small output.
We also have standard jaw crusher and European type jaw crusher. Their structures are as follow.

Features of European Type Jaw Crusher
Integrated Motor Installation
The integrated installation method of the motor base and the crusher frame saves the installation space of the jaw crusher. Due to the synchronous movement of the frame, motor seat, motor, and adjustable motor seat, the tension of the V-belt can be adjusted so that the V-belt has a longer service life.
Superior Cavity Design, Large Feed Size
With a symmetrical “V”-shaped cavity design, the toggle plate has a large inclination angle and a large stroke. Compared with the traditional PE series jaw crusher, the feed size is larger, the output is higher, the particle size is more uniform, and the jaw plate wear is reduced.
Convenient and Quick Adjustment of The Discharge Outlet
The C series jaw crusher adopts mechanical or hydraulic way to adjust the discharge opening. Compared with the gasket adjustment method, the double-wedge adjustment method is simpler, safer, and faster to save downtime.
Advantages and Features
Low noise and less dust.
The crushing ratio is large and the product size is uniform.
The structure is simple, the work is reliable and the operating cost is low.
The lubrication system is safe and reliable, the parts are easy to replace and the equipment is easy to maintain.
The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output.
Equipment energy-saving: single machine can save 15%-30% energy, and the system can save energy more than doubled.
The adjustment range of the discharge opening is large, which can meet the requirements of different users.
