Jaw Crusher


 

Product Introduction

Jaw crusher is an early crushing equipment, because of its simple structure, strong, reliable work, easy maintenance and repair, and relatively low production and construction costs, so it is still widely used in metallurgy, chemical industry, building materials, electricity, transportation and other industrial sectors; crushing crude, medium and fine crushing of various ores and rocks with compressive strength is 147-245 MPa. In recent years, in order to meet the needs of breaking high-strength and high-hardness micro-carbon ferrochrome in metallurgical, mining, construction and other industrial sectors, our factory has specially developed a strong jaw-type crusher. Jaw crusher is mainly used for medium size crushing of various ores and bulk materials. It is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. The higher compressive strength of crushed materials is 320 MPa.

Outstanding Advantages



Chose better materials for fabrication
Special jaw head structure ensures seal and prolongs bearing life.


Deep chamber crushing, high efficiency and energy saving.
The crushing chamber is deep and has no dead zone, which improves the feeding capacity and output. The crushing ratio is large and the particle size of the product is uniform.

High crushing strength and high yield 
The crusher has higher strength with the finite element analysis technology.
The bearing capacity is higher with the larger bearing size
All jaw crushers are equipped with bigger and more durable eccentric shaft bearings for the same size crushers. Their higher carrying capacity and effective labyrinth seals greatly prolong the service life of bearings.
The discharge outlet can be adjusted with more quick and conveniently.
Jaw crusher is equipped with wedge discharging and opening adjusting device, which is more simpler, safer and faster than the old gasket adjusting device.
 Special flywheel design
 Special flywheel design can effectively reduce vibration and make the machine run more smoothly.

 

Working Principle

20151114171642_3457.jpg

The working principle of this series of crushers is curved extrusion type. Its working principle is as follows: The motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the elbow plate and the movable jaw becomes larger, which pushes the movable jaw plate to approach the fixed jaw plate, and at the same time, the material is crushed or split to achieve the purpose of crushing material. When the moving jaw goes down, the angle between the elbow plate and the moving jaw decreases. Under the action of the pull rod and spring, the moving jaw plate leaves the fixed jaw plate. At this time, the crushed material is discharged from the lower mouth of the crushing chamber. With the continuous rotation of the motor, the moving jaws of the crusher move periodically to crush and discharge materials to realize mass production.
