Jaw Crusher Machine

Jaw Crusher Machine (Grease & Oil Lubricant Type)

A jaw crusher machine is a primary crusher used in various industries to break down large stones, rocks, and ores into smaller, more manageable pieces. It consists of a fixed jaw plate and a moving jaw plate, both of which form a V-shaped crushing chamber. The movable jaw moves back and forth against the fixed jaw, creating a compressive force to crush the material.

Here are key components and features of a typical jaw crusher machine:

1. Jaw Plates: The crushing chamber is formed by two jaw plates—one is fixed (stationary), and the other is movable. The crushing action occurs when the material enters the space between the two plates.

2. Movable Jaw: The movable jaw is attached to the eccentric shaft, which rotates and moves the jaw in a reciprocating motion. This motion compresses the material against the fixed jaw, breaking it into smaller pieces.

3. Fixed Jaw: The fixed jaw is part of the crusher frame and provides a stable platform against which the movable jaw crushes the material.

4. Eccentric Shaft: The eccentric shaft is connected to the movable jaw and is responsible for the up-and-down motion. It is usually powered by an electric motor.

5. Toggle Plate: The toggle plate is a safety device that connects the lower part of the movable jaw to the crusher frame. It provides support and acts as an overload protection mechanism by breaking if uncrushable material enters the crushing chamber.

6. Adjustment Mechanism: Some jaw crushers have an adjustable discharge opening, allowing users to control the size of the crushed material. This adjustment is typically achieved by changing the position of the toggle plate.

7. Bearings: Bearings support the moving parts of the jaw crusher, such as the eccentric shaft. Proper lubrication of these bearings is crucial for the efficient operation of the machine.

8. Feed Hopper: The feed hopper is the entry point for the material into the crushing chamber. It ensures a controlled and continuous supply of material to the crusher.

9. Crushing Chamber: The space between the two jaw plates where the actual crushing takes place.

Jaw crushers are widely used in mining, quarrying, recycling, and various industries where the reduction of large materials into smaller particles is necessary. They are commonly used for primary crushing but can also be used for secondary crushing depending on the application. The size and capacity of jaw crushers vary, and selecting the right machine depends on factors such as the type of material, required output size, and production capacity. Regular maintenance is essential to ensure the efficient and reliable operation of jaw crushers.
