Jaw Crusher

What is jaw crusher?

The jaw crusheruses the principle of mutual extrusion of jaws to process stone materials. Itis usually preferred for breaking large pieces of hard and abrasive materials,and is commonly used in primary and secondary crushing processes for various mineral rock crushing. Jaw crusher can process ore materials to medium particle size at one time. It often forms a complete sand and gravel production line together with cone crusher, impact crusher, sand making machine, etc.

Popular applicationsfor jaw crusher

Although jaw rock crusher is usually used in the primary crushing stage in the crushing production line. And the PEX series jaw crusher machine can also be used in the secondary crushing and fine crushing stages. We also produce portable jaw crusher for sale that can be more easily applied to various production sites. Jaw crusher has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance and economical operation cost.

Advantages of Daswell jaw crushe

• 1. The structure is simple and firm, and the production is efficient. Daswell jaw stone crusher has a relatively firm frame and can work under high pressure. The weight of the equipment is about 15% heavier than other manufacturers, and the structure is stronger and more impact-resistant.
• 2. The crushing ratio of jaw crusher for sale is large and the product particle size is uniform. The crushing work starts from the top of the crushing cavity,and the crushing ratio is effectively improved by adjusting the size of the discharge opening.
• 3. Easy maintenance and low cost. Easy maintenance and overhaul, greatly reduced downtime for repairs, and lower production and construction costs.
• 4. The V-shaped crushing cavity of small jaw rock crusher for sale is deep and has no dead zone, which improves the feeding capacity and output.
• 5. The adjustment range of the discharge port is large, and the production is efficient.

Different types of jaw crushers

According to the different movement mechanism of jaw crusher, it can usually be classified into two categories: double toggle jaw crusher and single toggle jaw crusher.

Double toggle jaw crusher

The movable jaw of the double toggle jaw crusher is suspended on the shaft and can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down, and drives the two thrust plates to also reciprocate, thereby pushing the movable jaw to reciprocate left and right to achieve crushing and discharging. In this way, the movable jaw does a kind of left and right reciprocating motion. The movement trajectory of each point on the movable jaw is an arc line centered on the suspension shaft. The movement trajectory is simple, so it is also called simple pendulum jaw crusher.

Single toggle jaw crusher

The motor of the single toggle jaw crusher drives the eccentric shaft to rotate through the belt and pulley. The movable jaw plate periodically reciprocates around the eccentric shaft to the fixed jaw plate, sometimes approaching and sometimes leaving. Its motion trajectory changes from circle to ellipse from top to bottom. In addition to being crushed by extrusion, the material is also subjected to gravity, so that the material will be discharged out of the crushing cavity under the action of the extrusion force and its own weight. The movable jaw of the single toggle jaw crusher is directly suspended on the eccentric shaft. When the eccentric shaft rotates in the counterclockwise direction, it directly drives the movable jaw plate to make complex swings.

Because the movement trajectory of each point on the movable jaw is complex, it is also called compound pendulum jaw crusher.

How does jaw crusher work

The jaw crusher is mainly composed of frame, eccentric shaft and bearing, main shaft, flywheel, toggle plate, fixed and movable jaw plate and other components. The working mode of the jaw crusher is the driving extrusion type, and the material is crushed in the crushing cavity composed of the movable jaw and the fixed jaw.

When the jaw rock crusher for sale starts to work, firstly, the stone is evenly fed into the feeding port above the jaw crusher by the vibrating feeder. Inside the machine, a crushing cavity is formed by the fixed crusher jaw plate fixed on one side of the crushing cavity and the movable jaw plate on the opposite side. The material will fall into this crushing chamber. The motor outside the machine drives the pulley to make the connected eccentric shaft reciprocate. The eccentric shaft will drive the movable jaw to move up and down. When the movable jaw rises, it will approach the fixed jaw plate, the crushing cavity will become smaller, and the material inside will be squeezed and crushed. When the movable jaw plate goes down, the movable jaw plate leaves the fixed jaw crusher plate, and the broken material falls. Crushed stone smaller than the size of the outlet will be discharged by gravity.
