A robust and dependable high-capacity jaw crusher suitable for laboratory and plant applications. The Model LMC Jaw Crusher is used by laboratories and processing companies to crush solid materials such as rocks or soil and ores. The material to be processed falls into the crushing chamber of the LMC Crusher via a guide chute and is crushed by crushing action of a static and a dynamic jaw plate until it passes the preselected gap of the crusher.

Jaw Crusher working principle
A jaw crusher is a primary crushing machine used in the mining and construction industry to break down large stones into smaller pieces.
It consists of a fixed jaw and a movable jaw, which are positioned in a "V" shape. The movable jaw exerts force on the rock by pressing it against the fixed jaw, creating a crushing motion.
The raw material, such as rock or concrete, is fed into the jaw crusher from the top through the feeding mechanism. The material enters the crushing chamber, which is composed of the fixed jaw and the movable jaw.
The movable jaw moves back and forth against the fixed jaw due to the eccentric shaft's rotation. This movement causes the two jaws to come together and crush the material between them.
The crushing action is similar to that of a nutcracker, where the jaws apply pressure to break the material.
As the sample is crushed, it is reduced in size and passes through the narrowest point between the two jaws, known as the discharge opening.
The size of the crushed material can be adjusted by using a setting mechanism to control the distance between the jaws.
Once the material is crushed to the desired size, it is discharged from the crushing chamber through the bottom opening. The jaw crusher continues to repeat this crushing process until the material is sufficiently small to pass through the discharge opening.
It can be operated manually or by using an electric motor to drive the eccentric shaft, which in turn drives the movable jaw.
Jaw crushers are commonly used in mining, quarrying, recycling, and construction industries to process various types of materials, including hard rocks, ores, and concrete. They are designed to handle large feed sizes and have a high crushing capacity. Additionally, some jaw crushers may have additional features such as toggle plates, which provide additional protection for the crushing chamber and allow for the adjustment of the discharge opening size.
LMC500 Jaw Crusher with Hydraulic Adjustment
This Custom version of the LMC500 Jaw Crusher is Equipped with a hydraulic adjustment and hydraulic opening mechanism, it offers enhanced safety, ease of use, and minimized downtime.
In the event that a piece of unbreakable material becomes lodged between the jaws, the hydraulic system allows the operator to quickly and safely open the crushing chamber.
This feature eliminates the need for manual intervention or disassembly, significantly reducing the risk of damage to the machine and improving operator safety.
Once the obstruction is cleared, the jaw gap can be precisely reset using the hydraulic adjustment control, ensuring consistent particle size output without the need for tools or manual recalibration.
This advanced hydraulic functionality makes the LMC500 ideal for demanding environments where reliability, safety, and ease of maintenance are critical.
