Introduction to jaw crusher

Jaw crusher is a common crushing equipment mainly used for crushing ores and rocks with various hardness. The jaw crusher mainly consists of a frame, an eccentric shaft, a large belt pulley, a flywheel, a moving jaw, a side guard plate, an elbow plate, a back seat of the elbow plate, a gap adjustment screw, a reset spring, a fixed jaw plate, a movable jaw plate, a motor, etc. It crushes materials through the periodic movement of the moving jaw, simulating the movement of the two jaws of animals, and subjecting the materials to comprehensive effects such as crushing, splitting, and bending, thereby completing the crushing operation.

Working principle of jaw crusher

Its working principle is based on the squeezing and crushing effect of the jaw plate. Specifically, a jaw crusher consists of two jaw plates, namely a fixed jaw plate and a swinging jaw plate. The swinging jaw plate is connected to the eccentric shaft through a connecting rod, and the rotation of the eccentric shaft causes the swinging jaw plate to produce periodic reciprocating motion. The ore or rock to be crushed enters the crushing chamber of the jaw crusher through the feeding port. With the reciprocating motion of the swinging jaw plate, the ore is clamped between the jaw plates and subjected to pressure, thus being crushed and crushed. The crushed material is discharged through the discharge port at the bottom of the crushing chamber, completing the crushing process.

Advantages of jaw crusher

Jaw crushers have the advantages of high crushing efficiency, large production capacity, and low energy consumption, and are therefore widely used in fields such as mining, metallurgy, construction, and chemical industry. In addition, it is suitable for primary and medium crushing operations and is commonly used in mining, construction, and road construction scenarios.

The Shanmei jaw crusher has the advantages of high production efficiency, good wear resistance, adjustable discharge, and easy maintenance. Its crushing chamber is deep and has no dead zone, which can improve the feeding capacity and output of crushed stones, and save energy consumption. In addition, the components of the jaw crusher are made of high-quality manufacturing materials, which have good pressure resistance and wear resistance, making the equipment efficient and durable. At the same time, the gasket type discharge port adjustment device makes the particle size of the material adjustable and more flexible.

Precautions for jaw crusher

However, jaw crushers generate high energy consumption when crushing ores with compressive strength exceeding 245MPa, so in some cases, their energy-saving and consumption reducing performance may not be ideal. However, due to its wide range of applications and good performance, jaw crushers are still widely used in many fields such as mining, smelting, building materials, highways, railways, water conservancy, and chemical industry.

In practical applications, jaw crushers are often used in conjunction with other crushing equipment in production lines to process various ores and bulk materials. Their finished products have uniform particle size and good particle shape, which can meet the high standard material requirements in the construction field.
