The Main Parts of the Jaw Crusher

Jaw crusher wear parts can be categorized into the jaw plate, toggle plate, side plate, tooth plate, triangle belt, and other components.

The accessories of a jaw crusher, also known as its wearing parts, are integral components of the crushing machine. The component requires replacement within a specified timeframe. It can be categorized into the jaw plate, toggle plate, side plate, tooth plate, triangle belt, and other components.

1) Jaw plate:

The jaw plate is a component with high wear resistance located inside the jaw crusher, which can be further classified into the fixed jaw plate and the movable jaw plate. The material is subjected to reciprocal compression between the fixed jaw plate and the movable jaw plate in the chamber of the jaw crusher, resulting in its fragmentation.

2) Toggle plate:

It is commonly referred to as the roof or thrust plate in the jaw crusher, serves a crucial safety function. The jaw crusher toggle plate is fabricated from HT200, ensuring stable chemical composition of raw materials and guaranteeing its mechanical properties. The toggle plate can be rapidly fractured to safeguard the main engine from damage and prevent motor burnout when subjected to an external force exceeding the rated load.

3) Side plate:

The side plate of the jaw crusher is positioned between the fixed tooth plate and the movable tooth plate, serving as a high manganese steel casting that primarily safeguards the frame wall of the jaw crusher throughout its entirety.

4) Tooth plate:

The movable jaw plate and fixed jaw plate are made of high manganese steel castings. To enhance their durability, the design incorporates a symmetrical shape, allowing for rotation and continued use when one end becomes worn. The movable tooth plate and the fixed tooth plate serve as the primary locations for stone crushing, with the movable tooth plate being installed on the moving jaw to provide protection.

5) Triangle belt:

When the motor transmits power, the triangular belt connects the motor’s belt pulley and the groove wheel, driving the eccentric shaft and causing the moving jaw to move reciprocally along a predetermined trajectory.
