Structural Design

The jaw crusher replacement parts cheek plate, is installed on either side of the crushing chamber, between the fixed jaw plate and the movable jaw plate. It is typically designed with an upper and lower plate, where the upper plate is a right-angled trapezoid with an excessive arc at the right angle. The short side of the upper plate is parallel to the long side of the lower plate, and both plates have the same slope. This design ensures stability and proper alignment during installation and operation.

Function

The primary function of the jaw crusher machine parts cheek plate is to protect the mainframe of the jaw crusher from wear and damage caused by the crushing process. It serves as a lining that prevents the abrasive forces of the material being crushed from wearing down the mainframe walls. Additionally, the cheek plate helps distribute the crushing forces evenly across the crushing chamber, reducing localized wear and improving the overall efficiency of the crusher.

Materials and Durability

Cheek plates are usually made from high manganese steel (Mn13Cr2). High manganese steel is known for its toughness, ductility, and ability to work-harden with use, making it highly suitable for withstanding the significant wear and impact forces in a jaw crusher. The cheek plate is designed to withstand large impact forces without deformation and has good tensile strength and toughness. These properties ensure that the cheek plate can endure the rigors of continuous operation and provide long-lasting protection for the crusher.

Impact on Crushing Efficiency

The crusher part cheek plate contributes to the crushing efficiency by optimizing the crushing angle and improving the grip on the material being crushed. The design and configuration of the cheek plate can vary depending on the specific jaw crusher model and application requirements. Properly designed cheek plates can help reduce the wear rate of other components, such as the jaw plates, and ensure a more uniform crushing process.

Maintenance and Replacement

Crushing machine parts cheek plates are subject to significant wear and need to be periodically replaced or adjusted. They are designed to be easily removed and replaced when worn, which helps extend the lifespan of the crusher's mainframe. Regular inspection and maintenance of the cheek plates are essential to ensure their integrity and effectiveness in protecting the crusher. Proper maintenance can help reduce downtime and lower the overall operating costs of the jaw crusher.
