Reliable primary crushing PE type jaw crusher Mining Machinery crusher plant

Jaw crusher (jaw crusher) is an earlier crushing equipment. Its structure is simple, sturdy, reliable, easy to maintain and repair, and relatively low production and construction costs. Therefore, it is still widely used in metallurgy, chemical industry, building materials, In the industrial sectors such as electric power and transportation, the jaw crusher is generally divided into two types: compound pendulum and simple pendulum, which are mainly used for coarse and medium crushing. In recent years, compound pendulum jaw crushers for fine crushing and high-strength, high-hardness micro-carbon ferrochrome powerful jaw crushers have appeared. Jaw crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries.

The jaw crusher is used for coarse, medium and fine crushing of various ores and rocks with a compressive strength of 147～245MPa. The maximum compressive strength of the crushed material is 320Mpa. Performance characteristics of the jaw crusher: The jaw crusher has a large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and low operating costs. The working principle of the jaw crusher: When working, the motor drives the eccentric shaft to rotate through the belt pulley, so that the moving jaw periodically approaches and leaves the fixed jaw, thereby squeezing, rubbing, and grinding the material multiple times, making the material change from large to small, gradually Fall down until it is discharged from the discharge port.

The structure of the jaw breaker mainly consists of a frame, an eccentric shaft, a large pulley, a flywheel, a movable jaw, a side guard, a toggle plate, a toggle back seat, a clearance adjustment screw, a return spring, a fixed jaw plate and a movable jaw plate. The toggle also serves as an insurance. The PE and PEX series jaw crushers are powered by a motor, through the motor pulley, the eccentric shaft is driven by the V-belt and the grooved wheel, so that the movable jaw crushes the material according to the predetermined trajectory to reciprocate, so as to enter the fixed jaw and movable jaw. The material in the crushing cavity composed of the plate and the side guard is crushed, and the finished material is discharged through the lower discharge port to obtain the desired material.

Performance characteristics
⒈Simple structure, convenient maintenance and use; stable performance, low operating cost; large crushing ratio.
⒉The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output;
⒊The crushing ratio is large and the product size is uniform
⒋Gasket-type discharge opening adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment.
