Description
Introduction to Jaw Crusher:
A jaw crusher consists of a fixed jaw and a movable jaw that form a V-shaped chamber. The movable jaw exerts force on the rock by pressing it against the fixed jaw, crushing the material between them. This action results in the reduction of the material size, making it suitable for further processing or disposal.
Components of a Jaw Crusher:
Fixed Jaw: The fixed jaw is an integral part of the jaw crusher’s structure and remains stationary during operation. It provides a surface against which the material is crushed by the movable jaw.
Movable Jaw: The movable jaw is attached to a swinging mechanism that allows it to move back and forth. Its motion crushes the material against the fixed jaw, reducing it to the desired size.
Toggle Plate: The toggle plate connects the movable jaw to the rest of the crusher’s structure and helps control the movement of the jaw during operation.
Eccentric Shaft: The eccentric shaft is responsible for the rotational movement of the movable jaw. It converts the input power into the crushing motion required to break down the material.
Bearings: Bearings support the movable jaw and help reduce friction during operation, ensuring smooth movement and efficient crushing.
Flywheel: The flywheel is a heavy wheel that helps store energy and smoothen the crushing process by maintaining a consistent speed and momentum.
Adjustment Mechanism: Jaw crushers often include an adjustment mechanism that allows for the setting of the desired size of the crushed material. This mechanism can be manual or hydraulic, depending on the crusher design.
Working Principle of a Jaw Crusher:
Size Reduction: The primary function of a jaw crusher is to reduce the size of large rocks into smaller particles suitable for further processing.
Crushing Mechanism: As the movable jaw moves back and forth, it exerts pressure on the rock, crushing it against the fixed jaw. This crushing action breaks the material into smaller pieces.
Feed Opening: The feed opening of a jaw crusher determines the maximum size of the material that can be fed into the crushing chamber. Properly sized material enters the chamber for crushing.
Discharge Opening: The discharge opening controls the size of the crushed material that exits the jaw crusher. Adjusting the discharge opening allows for customization of the final product size.
Efficiency and Capacity: Jaw crushers are designed to maximize efficiency and production capacity by continuously crushing incoming material while maintaining a consistent output size.
Uses of Jaw Crushers in Various Industries:
Mining: Jaw crushers are commonly used in the mining industry to crush hard rock ores for further processing, such as extracting valuable minerals.
Construction: In construction projects, jaw crushers are employed to crush construction debris, concrete, and other materials for recycling or disposal.
Demolition: Jaw crushers are essential tools in demolition projects, where they are used to break down structures, concrete, and other materials.
Quarrying: In the quarrying industry, jaw crushers are used to process large rocks and stones extracted from quarries into smaller, more manageable sizes for use in construction and other applications.
Recycling: Jaw crushers play a crucial role in the recycling industry by crushing and processing recycled materials such as concrete, asphalt, and demolition waste.
Benefits of Using Jaw Crushers:
Versatility: Jaw crushers can handle a wide range of materials, making them versatile tools in various industries.
Efficiency: Jaw crushers offer efficient crushing capabilities, reducing large rocks into smaller, more manageable sizes in a single pass.
Durability: Jaw crushers are robust machines designed to withstand heavy-duty use in demanding environments, ensuring long-term reliability.
Adjustability: The ability to adjust the size of the crushed material allows for customization of the final product to meet specific requirements.
Cost-Effectiveness: Jaw crushers are cost-effective solutions for primary crushing operations, offering high productivity and low maintenance requirements.
In conclusion, jaw crushers are essential primary crushing machines used in a variety of industries for breaking down large rocks into smaller particles. Their robust construction, efficient crushing capabilities, and versatility make them indispensable tools for material processing, construction projects, mining operations, and recycling efforts.

Correct Operation of Jaw Crusher
A jaw crusher, as one of the modern crushing equipment, has a great crushing capacity and wide application. Generally, working as a medium crusher, it is a standard crushing machine for the mining process and aggregate processing, quarry plant, etc. The correct operation directly affects the jaw crusher’s working effect and service life. The summary of correct operation matters needing attention is as follows.
Central parts of the jaw crusher have the frame, eccentric shaft, belt, freewheel, moving jaw plate, side guard, elbow plate, the back seat of elbow plate, adjusting screw, reset spring, and fixed jaw plate.
No load startup
The crusher needs to start up when no loading, and after running for a while, gradually increase ore feeding. If the crusher makes an unusual sound, it should stop running, find out the reasons.
Blocking
Sometimes, a large size rock plugs up the feeder mouth, in the event of a lock, rolling over the large stone makes the feeder mouth free at first. If blocking in the crusher chamber, it should stop feeding until the chamber is clear. For Your Attention, it is strict that use specialized tools to clear the obstruction instead of using a hand.
Feeding
It is essential that keep a steady status of material feeding and processing; the crusher chamber cannot be allowed to be filled with stone material, meanwhile, prevent irrelevant objects such as a drill, and shovel from entering the crusher.
Lubrication
Lubricating oil helps the smooth and efficient operation of the machine. What’s more, the eccentric bearing temperature cannot exceed 600 °c.

Advantages and Disadvantages
What’s a Jaw Crusher?
A jaw crusher is a compression-type crusher, usually used as a primary crusher set at the front of the ore or rock-crushing plant to reduce hard rock size. Jaw rock crushers commonly double-toggle jaw crushers, are composed of a fixed jaw and a moving jaw. The discharging stone particle size can be controlled by changing the discharge port. Owing to its high crushing capacity and hard material efficiency, jaw crushers are a good alternative to primary gyratory crushers.
How Many Types of Jaw Crushers?
Single toggle jaw crushers and double toggle jaw crushers; industrial jaw crushers and laboratory small jaw crushers; diesel engine jaw crushers; hydraulic jaw crushers; stationary, mobile jaw crushers, track mounted jaw crushers; jaw crushers.
What’s The Jaw Crusher’s Size and Capacity?
The size of a jaw crusher is determined by the rectangular or square opening (feeding port) at the top of the jaws. The sheet below shows different gaps for coarse and fine crushing applications, Jaw Crusher (coarse crushing), and Jaw Crusher (fine crushing).
