PE series jaw crusher

The PE series jaw crusher (referred to as jaw crusher) is mainly used for the medium particle size crushing of various ores and bulk materials. It can crush materials with a compressive strength of less than 320Mpa, and is divided into two types: coarse crushing and fine crushing. The PE series products have complete specifications, with a feeding particle size of 125mm~750mm, and are primary crushing equipment. The PE series jaw crusher (jaw crusher) is widely used in various industries such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical engineering.

Performance characteristics of PE series jaw crusher:

1. The crushing chamber is deep and has no dead zone, improving the feeding capacity and output;

2. Its crushing ratio is large and the product particle size is uniform;

3. The gasket type discharge port adjustment device is reliable and convenient, with a large adjustment range, increasing the flexibility of the equipment;

4. The lubrication system is safe and reliable, with convenient component replacement and low maintenance workload;

5. Simple structure, reliable operation, and low operating costs.

6. Equipment energy-saving: Single machine energy-saving by 15% to 30%, system energy-saving by more than twice;

7. The adjustment range of the discharge port is large, which can meet the requirements of different users;

8. Low noise and less dust.

Structure composition of PE series jaw crusher:

The PE series jaw crusher is mainly composed of a frame, an eccentric shaft, a large belt pulley, a flywheel, a movable jaw, a side guard plate, an elbow plate, a back seat of the elbow plate, a clearance adjusting screw, a reset spring, a fixed jaw plate, and a movable jaw plate, among which the elbow plate also plays a safety role.

In the process of breaking large stones into small ones, a crusher is usually referred to as the "main" crusher. When feeding the jaw crusher, the material is poured into the crushing chamber containing jaw teeth from the top inlet. Echi uses tremendous force to push the material towards the chamber wall, breaking it into smaller stones. The support for the movement of the jaw is an eccentric shaft that runs through the body structure. Eccentric motion is usually generated by a flywheel fixed at both ends of the shaft. Flywheels and eccentric support bearings often use spherical roller bearings, and the working environment of the bearings is harsh. The bearing bears large impact loads, corrosive sewage, and high temperatures. Despite the harsh working environment, the jaw crusher still needs to work very reliably, which is a key factor in ensuring production efficiency.

Working principle of PE series jaw crusher:

The crushing method of the PE series jaw crusher is a curved extrusion type, with an electric motor driving the belt and pulley. The eccentric shaft moves the movable jaw up and down. When the movable jaw rises, the angle between the elbow and the movable jaw increases, thereby pushing the movable jaw closer to the fixed jaw. At the same time, the material is subjected to multiple crushing such as extrusion, rubbing, and grinding; When the moving jaw descends, the angle between the elbow plate and the moving jaw decreases, and the moving jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower port of the crushing chamber. With the continuous rotation of the electric motor, the crushing jaw performs periodic crushing and discharging, achieving batch production.
