Function
- Eloquent Jaw crusher EJC 40 is a sturdy and powerful forced-feed crusher. The feed material is introduced through a no-rebound hopper and enters the crushing chamber. Size reduction occurs in the wedge-shaped area between the stationary crushing arm and a moving arm, which is driven by an eccentric shaft.
- The elliptical motion crushes the sample, allowing it to fall by gravity. Once the sample size is smaller than the discharge gap width, it drops into a removable collector. The crusher features a continuous gap width adjustment with a digital display, ensuring optimal size reduction based on the set gap width value.
Eloquent Jaw crushers s primary function :
- Size Reduction: EJC is designed to reduce large-sized rocks, ore, or other materials into smaller, more manageable pieces. This is achieved by applying compressive force, breaking the material between a stationary and a moving jaw.
- Primary Crushing: Eloquent Jaw crushers are commonly used as the first stage in the crushing process. They handle large, coarse materials and prepare them for secondary crushing stages, such as with cone crushers or impact crushers.
- Material Preparation: By reducing the size of the material, jaw crushers make it easier to handle and transport. They also prepare the material for further processing, such as grinding or additional crushing.
- Consistent Product Size: The jaw crusher allows for adjustable discharge settings, enabling operators to control the size of the output material. This ensures a consistent product size suitable for various applications.
- Material Handling Efficiency: The crusher facilitates efficient handling of materials in various industries, including mining, construction, demolition, and recycling. It reduces the need for manual labor and speeds up processing times.
- Reduction of Material Hardness and Abrasiveness: Jaw crushers are effective for breaking down hard and abrasive materials, making them suitable for processing tough rocks and ores.
- Separation and Sorting: By breaking down materials into smaller pieces, jaw crushers help in the separation and sorting processes, enabling the extraction of valuable minerals or the recycling of materials.
Working Principle
The working principle of Eloquent jaw crusher is based on the application of compressive force. Here’s a detailed explanation:
- Structure: EJC consists of two main plates or jaws—one fixed and one movable. The fixed jaw is mounted in a V-shape, while the movable jaw is positioned at an angle and moves towards and away from the fixed jaw.
- Crushing Chamber: The area between the two jaws forms a crushing chamber, which narrows from top to bottom. The size of this chamber determines the maximum size of the feed material that the crusher can handle.
- Operation: The movable jaw is attached to an eccentric shaft, which imparts a back-and-forth motion. This motion is elliptical in nature and is generated by a motor-driven belt and pulley system.
- Size Reduction Process:
- Feeding: The material to be crushed is fed into the top of the crushing chamber through a hopper.
- Crushing: As the movable jaw moves toward the fixed jaw, the material is compressed and crushed into smaller pieces. This movement reduces the material’s size, and the pieces break apart.
- Discharge: Once the material is smaller than the gap between the jaws, it falls due to gravity into a collection container or onto a conveyor belt for further processing.
- Adjustment of Discharge Gap: The size of the discharge gap, and hence the final particle size, can be adjusted by altering the position of the movable jaw. This adjustment can be manual or hydraulic, depending on the crusher’s design.
- Principle of Mechanical Advantage: The design of the jaw crusher takes advantage of mechanical leverage to achieve effective crushing. The eccentric motion creates high pressure at a single point, ensuring efficient size reduction.
