What is a Jaw Crusher?
A jaw crusher is a machine used in the fields of mining, metallurgy, building materials, and highway engineering to reduce the size of large rocks, ores, and other materials. It operates by compressing the material between a stationary piece of steel (the jaw) and a moving piece (the swing jaw or movable jaw). The material is fed into the top of the crusher and is crushed as it moves down through the crushing chamber.

Jaw Crushers Assembly Process
Jaw crushers are commonly used in the mining and aggregate industries to crush materials. They operate by compressing rock between a fixed and a moving jaw. Here’s a basic overview of how jaw crushers work:
-
- Feed Hopper: Raw materials are fed into the crusher through a vibrating feeder or a grizzly feeder. The feeder distributes the material over the entire length of the crusher.
- Jaw Crusher Components:
-
-
- Movable Jaw: The movable jaw is attached to a swinging lever, which is connected to an eccentric shaft. This shaft rotates and moves the movable jaw, causing the material to be crushed.
- Fixed Jaw: The fixed jaw is stationary and acts as a support for the movable jaw. It provides a surface against which the material can be crushed.
- Toggle Plate: The toggle plate is a mechanism that helps to transmit power and protect the crusher from overloading. It is connected to the movable jaw and helps in adjusting the size of the discharge opening.
-
- Crushing Process:
-
- As the eccentric shaft rotates, the moving jaw moves up and down, creating a squeezing motion.
- Material is crushed between the two jaws as the space between them narrows.
- Discharge: The crushed material is discharged through the bottom of the crusher, either directly into a bin or onto a conveyor belt.
Types of Jaw Crushers:
- Overhead Eccentric (Single Toggle) Crusher: The eccentric shaft is positioned below the swinging jaw, providing a higher stroke than the overhead eccentric (double toggle) type.
- Double Toggle Jaw Crusher: In this type, the swing jaw is pivoted at the top and the other jaw is positioned at a toggle joint.
Checklist for Choosing the Best Jaw Crusher:
- Material Characteristics: Hardness, abrasiveness, and moisture content of the material being crushed.
- Capacity Requirements: Ensure the crusher can handle the desired throughput.
- Size of Feed Material: The size distribution and maximum size of the feed material.
- Maintenance and Operating Costs: Consider the ease of maintenance and the overall operating costs.
- Adjustability of Settings: The ability to adjust the discharge setting to control the size of the crushed material.
- Crusher Size and Weight: Suitability for the available space and transportation requirements.
- Wear Parts: Availability and cost of wear parts, such as jaw plates.
- Safety Features: Check for safety features to protect operators during maintenance or in case of a malfunction.
- Manufacturer Reputation: Consider the reputation and reliability of the manufacturer.
- Application Specifics: Some crushers are better suited for specific applications, so consider the unique requirements of your operation.
