What is jaw crusher?


The jaw crusher is the basic crushing equipment of the mine crushing production line. It coarsely crushes the rough stone extracted from the quarry. It is the stone that must be crushed into the production line. As an indispensable crushing equipment, it is also a crushing equipment. Popular among devices.

Jaw Crusher Construction And Working:

1. Frame: The frame is a four-wall rigid frame with upper and lower openings. It is used to support the eccentric shaft and bear the reaction force of the crushed materials. It requires sufficient strength and rigidity. It is generally cast with cast steel as a whole, and small machines can also be replaced by cast iron. Cast steel.
2. Jaw plate and side guard plate: Both the fixed jaw and the movable jaw are composed of a jaw bed and a jaw plate. The jaw plate is the working part and is fixed on the jaw bed with bolts and wedge irons.
3. Transmission parts: The eccentric shaft is the main shaft of the jaw crusher, which is subjected to huge bending and torsion forces and is made of high carbon steel. The eccentric part must be finished, heat-treated, and the bearing lining shall be cast with babbitt alloy. One end of the eccentric shaft is equipped with a belt wheel, and the other end is equipped with a flywheel.
4. Adjusting device: The adjusting device includes wedge type, backing plate type and hydraulic type, etc., generally wedge type, composed of two front and rear wedges. The front wedge can move back and forth to resist the rear push plate; the rear wedge is The adjustment wedge can be moved up and down. The inclined surfaces of the two wedges are inverted and fit together, and the rear wedge is moved up and down by the screw to adjust the size of the discharge port.
5. Flywheel: The flywheel of the jaw crusher is used to store the energy during the idle stroke of the moving jaw, and then used for industrial formation to make the mechanical work more uniform. The belt wheel also functions as a flywheel. The flywheel is often made of cast iron or Made of cast steel.
6. Lubrication device: The eccentric shaft bearing usually adopts centralized circulation lubrication. The supporting surface of the spindle and thrust plate is generally lubricated with grease through a manual grease gun.

How Does a Jaw Crusher Work?

As far as jaw crushers are concerned, although the structure types are different, their working principles are basically similar, except that the movement trajectory of the moving jaw is different. In a nutshell, when the movable jaws periodically reciprocate the fixed jaws around the suspension axis, sometimes approaching and sometimes leaving, when the movable jaws approach the fixed jaws, the ore between the two jaws , Crushed by the combined action of crushing, splitting and bending; when the movable jaw leaves the fixed jaw, the crushed ore is discharged through the discharge port of the crusher under the action of gravity.

Jaw Crusher Price:

The price of jaw crusher is affected because of its size, model, brand, etc., so how do we choose a cost-effective jaw crusher equipment?
The choice of jaw crusher is actually not difficult. First of all, we must understand what kind of effect the jaw crusher should achieve in the crushing production line: 1. Meet the needs of the mine. 2. The equipment is durable. 3. Equipment maintenance guarantee. So what do these three points mean?
1. Meet the needs of mines
Reaching the mine demand can be divided into two points, operation demand and emission demand. The jaw crusher must meet the daily operation demand and ensure that the daily output of the production line meets the operation demand. Emission requirements require that the pollution generated by the crusher must meet the emission standards. In recent years, green environmental protection has been paid more and more attention. The development of crushing operations and the excavation of stones have an impact on the environment. The emission requirements are relatively strict. When choosing a jaw crusher, try to look for a low-consumption and green direction, which can save a lot of trouble.

2. The equipment is durable
The crushing production line in the mining industry is a long-term operation, and the jaw crusher must also have the characteristics of long-lasting durability. If you want to obtain greater benefits, the early investment in the equipment is very important. When choosing equipment, you can’t just look at the price. To understand the performance and durability of the equipment, the long-lasting and stable production line can be long-lasting.

3. Equipment maintenance guarantee
Before the equipment is purchased, experienced people will pay attention to the after-sales maintenance service of the jaw crusher equipment, because some problems may occur during the use of the equipment. If the equipment is not properly maintained, the probability of failure will increase. After-sales maintenance is to insure the equipment. There is no need to find someone to repair the equipment when it fails. Moreover, some equipment brands are different, and their structures and components are also different. The replacement of other parts will affect the performance of the equipment, so after-sales maintenance service It is a necessary guarantee for long-term production line operation equipment.
