What is a jaw crusher machine?
Jaw crusher machine, simulating the two jaws of animals, crushers materials in its crushing chamber formed by a movable jaw plate and a fixed jaw plate. It is widely used in heavy mining, metallurgy, sand and gravel, quarried materials, construction and demolition recycling, transportation, water conservancy and other industries. Moreover, material’s compression strength should be less than 320Mpa.
Generally, a frame, an eccentric shaft, a large pulley, a flywheel, a side guard, a toggle plate, a toggle back seat, a clearance adjustment screw, a return spring, a fixed jaw plate and a movable jaw plate compose the jaw rock crusher. Our Daswell machinery has PE series jaw crusher and PEX series jaw crusher for sale. The widespread adoption of PE series jaw crusher is widely in the primary crushing of various ores and materials, such as coarse and medium crushing. In addition for customers’ requirements, PEX series jaw crusher is suitable for fine and medium material crushing.

Advantages and characters
- Simple and stable structure
The frame of the jaw stone crusher is relatively solid and it can work under high-strength pressure. The weight of our equipment is about 15% heavier than other manufacturers. The structure is stronger and more impact resistant.
- Large crushing ratio and uniform product granularity
The crushing work starts from the top of the crushing chamber. By adjusting the range of the discharge port could increase the crushing ratio effectively. Stable work makes the uniform product size.
- Convenient to maintenance and low operating costs
The jaw rock crusher is safe and reliable, convenient to replace parts, easy to maintain. In addition, quick jaw crusher maintenance will shorten the downtime and reduce your loss. High-performance equipment to increase profitability, production and construction costs are relatively low.
- Energy conservation and long service life
The jaw crusher machine has a fixed jaw plate and a swing jaw plate. It is more conducive to crushing harder materials. So that it has excellent performance of high processing capacity and low energy consumption. Jaw crusher’ special crushing chamber is more economical because users could adjust its jaw plate’s position to lengthen service life.
- Wide range of application
Due to the wide adjustment range, reasonable structure and less space of the discharge opening. It can suit the various processing requirements of users. So that it is often widely used in the crushing production of many industries.
What is the working principle of jaw crusher?
Jaw rock crushers machine operate according to the principle of pressure crushing. The motor drives jaw crushers, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the movable jaw runs down. Then the feed materials crushes into pieces. When the movable jaw runs up, that angle becomes bigger quickly. And the movable jaw plate leaves the fixed jaw plate under the action of pole and spring. At last the materials drop out of the crushing chamber.
Why choose a jaw crusher?
The jaw crusher machine uses a rudimentary and reliable technology that does not require much maintenance or engineering knowledge. They are the most popular crushers in the world. Jaw crushers are particularly suitable when the main objective is to reduce large blocks into smaller pieces, then the other machines would process them.
The structure, function, productivity and other features of the jaw crusher reflect the level of advanced technology available today, solving the problems of low productivity and maintenance and assembly difficulties. It is the ideal coarse crusher equipment to meet your needs.

Types of jaw crusher machine
There are two main groups of jaw crushers machine, single-toggle jaw crushers and double-toggle jaw crushers, classified according to their jaw movement mechanism.
In single-toggle jaw crushers, the movable jaw is supported by the bearing on an eccentric shaft driven by the pitman to which it is attached. Then a toggle plate at the bottom of the moveable jaw support the pitman. Toggle plate compressed between moveable jaw and main body. This mechanism ensures that the moving jaw moves in an elliptical orbit. Through this movement, the movable jaw applies both pressure and friction forces to the material.
In double-toggle jaw crushers, the pitman is mounted on fixed non-eccentric shaft that situated at the top of the crusher. There are two toggle plates, one on the left and one on the right, are linked to the pitman that is hinged to the driven camshaft. The toggle plate on the left links to the jaw-supporting block, while the one on the right links to the main body.
A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate materials, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.
