The crushing ratio is an important evaluation index of jaw crusher, which is generally 3-6. The particle size of the material after crushing is relatively uniform. The equipment is energy-saving, with a single machine saving 15%-30% of electricity and a system saving more than doubled. It can meet the requirements of different users.
The jaw crusher is a widely used crushing equipment. It consists of two jaw plates, the movable jaw, and the static jaw, which form a crushing cavity. It stimulates the movement of the two jaws of an animal to complete the material-crushing operation. As a primary crusher, it is mainly used to break large pieces of ore or rock into smaller particle sizes for further secondary or fine-crushing processing.
Jaw crushers are available in various models and specifications, such as PE-250×400, PE-400×600, PE-500×750, PE-600×900, PE-750x1060, PE-900x1200, PE-1200x1500, etc. In different models, The crushers differ in terms of feed port size, maximum feeding particle size, discharge port adjustment range, processing capacity, motor power, and weight.
There are many types of jaw crushers, and different types of stone crushers have obvious differences in production capacity.
The smallest model of jaw crusher has a production capacity of 5-20t/h, while the largest model PE-1500×1800 coarse jaw crusher has a production capacity of 520-1100t/h.
It can be seen that the adaptability of jaw crushers in production capacity is very wide.
The discharge port of the jaw crusher can be adjusted in size, and the particle size of the material can be controlled by adjusting the size of the discharge port.
The adjustment range of the discharge port of the jaw crusher is generally between 10~300mm, and the specific range may vary depending on the model and specifications.
The width of the discharge port can be changed by manually rotating the bolts on the discharge port or adjusting the wedge.
Jaw crusher is suitable for crushing a variety of materials, including limestone, river pebbles, granite, basalt, iron ore, quartz, shale, sandstone, etc. Therefore, it is widely used in mining, construction, highways, railways, and other fields.
The jaw crusher is driven by an electric motor, which drives the eccentric shaft to rotate through a belt and a pulley. The rotation of the eccentric shaft causes the movable jaw plate connected to it to move up and down periodically with the eccentric shaft as the center.
The movable jaw plate is connected to the eccentric shaft through a connecting rod. As the eccentric shaft rotates, the movable jaw plate moves up and down, making it approach or leave the fixed jaw plate. When the movable jaw plate rises, the angle between the toggle plate and the movable jaw increases, pushing the movable jaw plate to approach the fixed jaw plate; when the movable jaw plate descends, the angle between the toggle plate and the movable jaw decreases, and under the action of the pull rod and spring, the movable jaw plate leaves the fixed jaw plate.
When the movable jaw plate approaches the fixed jaw plate, the material is sandwiched between the two jaw plates, and subjected to pressure and shear force, resulting in crushing.
