With more than 40 years of experience in crushing engineering, FTM Machinery has specially developed high-performance jaw crushers, bringing breakthroughs to stone production lines.

Main parts of the jaw crusher

A jaw crusher consists of several main parts that work together to provide crushing functionality.

The basic structure of a jaw crusher includes the fixed jaw plate, movable jaw plate, toggle plate, eccentric shaft, flywheel, etc.

Among these parts, jaw plates (one fixed, one movable) are the most easily worn parts in the jaw crusher. Therefore, the jaw plate should be checked and replaced regularly to use the machine efficiently. Learn How to Choose the Right Jaw Plate.

Other part names and functions of the jaw crusher:

• Frame: Keep the machine in place and protect it to reduce abrasion.
• Bearing: Support the rotating components of the jaw crusher, such as the eccentric shaft and flywheel.
• Tension rod: Control the movement of the movable jaw and prevent it impact the front main frame in any situation.
• Adjusting set: Change the discharging opening size of the crusher to satisfy different customers' requirements.

Hot types of jaw crusher

Jaw crusher machine was first invented by Whitney Blake in 1858. On this basis, FTM Machinery introduces advanced technology and gradually launches 4 hot types of jaw crushers: PE/PEX series, HD German version series, CJ European version series, and mobile jaw crushers.

1. PE/PEX jaw crusher

PE/PEX jaw crusher is an earlier type with a simple structure. The PE type is a primary jaw crusher, and the PEX type is a secondary jaw crusher. It is the main crushing equipment in the small stone production lines.

• Maximum feed size: ≤1,200 mm
• Discharge particle size: 10–350 mm
• Capacity: 1–1,200 t/h

2. HD German type jaw crusher

HD series jaw crusher is developed by FTM Machinery combined with German crushing technology. The large inclination angle of the toggle plate makes the output higher and the particle size more uniform. It optimizes the crusher cavity and performs well in processing hard materials.

• Maximum feed size: ≤900 mm
• Discharge particle size: 45–225 mm
• Capacity: 50–750 t/h

3. CJ European type jaw crusher

CJ series jaw crusher is a crushing equipment with advanced technology, which has the advantages of small space occupation, large crushing ratio, and high processing capacity. It is the best choice for large and medium-sized stone production lines.

• Maximum feed size: ≤1,040 mm
• Discharge particle size: 60–300 mm
• Capacity: 105–1,280 t/h

4. Mobile jaw crusher

It is composed of a jaw crusher, vibrating feeder, screening equipment, conveying equipment, etc., and becomes a walking coarse crushing production line. Its application saves time spent on material transportation and production costs.

How does a jaw crusher work?

The working principle of a jaw crusher is to crush and break the material through the moving jaw plates. The belt and the pulley are driven by the motor, and the movable jaw is fixed to reciprocate up and down through the action of the eccentric shaft. The moving track of the movable jaw is an arc with the mandrel as its center.
