How does the crusher work?
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.

Questions about the crusher
What size Jaw Crusher do I need?
The size of the Jaw Crusher you need depends on the maximum size of the material to be crushed, the tons per hour rate to be processed, the desired size of the discharge material, and the operating hours per day. F100 is the maximum gape opening, F80 is the feed size, and P80 is the percent passing the closed side setting in tph.
Can I feed my Jaw Crusher coarse and fine material at the same time?
Yes, the Jaw Crusher can handle both coarse and fine materials, but it's important not to exceed the F80 rule for top size. Removing fine material equal to the closed side setting before it enters the crusher helps maintain a steady feed rate and promotes inter-particle crushing, which enhances performance and prolongs the life of the jaw dies.
Can I close circuit the feed to my Jaw Crusher?
Generally, Jaw Crushers operate in an open circuit. However, they can be used in a close circuit if the return load does not exceed 20% of the total feed and the raw feed is free of fines smaller than the closed side setting.
How often should I inspect my Jaw Crusher?
Regular inspections are crucial for optimal performance. Check the crusher daily for any unusual noises, vibrations, or wear. Perform a more thorough inspection weekly and schedule a comprehensive maintenance check monthly.
What materials can a Jaw Crusher process?
Jaw Crushers are versatile and can crush a variety of materials, including hard rock, ore, gravel, and recycled concrete. They are particularly effective for materials with a high compressive strength.
How do I adjust the discharge size of my Jaw Crusher?
The discharge size can be adjusted by changing the closed side setting (CSS) of the Jaw Crusher. This can usually be done by adjusting the toggle plate or hydraulic system, depending on the crusher model.
What is the role of the toggle plate in a Jaw Crusher?
The toggle plate in a Jaw Crusher serves as a safety mechanism. It breaks under excessive stress to prevent damage to the crusher. It also helps in adjusting the crusher settings to control the output size.
How can I extend the life of my Jaw Crusher parts?
To extend the life of your Jaw Crusher parts, ensure proper feeding practices, avoid overloading, and maintain a consistent feed size. Regularly inspect and replace worn parts, and use high-quality manganese steel for the jaw dies.
What is the difference between a single-toggle and a double-toggle Jaw Crusher?
A single-toggle Jaw Crusher has one toggle plate and operates with a more compact design. A double-toggle Jaw Crusher has two toggle plates and offers higher throughput and better handling of hard, abrasive materials.
How does inter-particle crushing benefit the Jaw Crusher’s performance?
Inter-particle crushing occurs when particles crush each other under compressive force, leading to improved product shape and reduced flat or elongated particles. This process also helps in equal work hardening of the jaw dies, extending their lifespan.
