A jaw crusher is a crushing equipment used to break hard materials such as stone, ore, or aggregate. It gets its name from the crushing process, which involves compressing the material between a fixed and a movable jaw plate. Jaw crushers are commonly used in primary crushing operations.

How Does It Work?

  1. Feeding: Material is fed into the crusher through the top feed opening.

  2. Compression and Crushing: The movable jaw plate moves back and forth toward the fixed jaw plate. During this movement, the material is compressed and crushed between the two jaws.

  3. Discharge: The crushed material is discharged through the bottom discharge opening.

Sizes and Technical Specifications:
Jaw crushers are produced in various capacities and sizes. They generally have the following features:

  • Feed Opening: Varies between 600 mm and 1200 mm.

  • Discharge Opening Adjustment Range: Varies between 50 mm and 200 mm.

  • Capacity: Ranges from 50 to 800 tons per hour.

  • Engine Power: Ranges from 75 kW to 200 kW.

  • Weight: Between 10 tons and 50 tons.

Applications:

  • Quarries

  • Mining sites

  • Recycling of construction and demolition waste

  • Aggregate production

Importance:
Jaw crushers are preferred for crushing hard materials due to their high crushing efficiency and durable structure. They also offer an economical solution with their simple working principle and low maintenance costs.
