What are the fixed jaw plate and the moving jaw plate?
The jaw plates of a jaw crusher are its critical wear-resistant components, typically divided into a fixed jaw plate and a moving jaw plate. During operation, the moving jaw plate performs a reciprocating motion while maintaining a specific angle relative to the fixed jaw plate, enabling it to crush materials. As a result, jaw plates are highly susceptible to wear and tear, especially after prolonged use.

Position and Appearance Description of Jaw Crusher Tooth Plates
The jaw plate of a jaw crusher, commonly referred to as the "jaw plate," is divided into two parts: the fixed jaw plate and the moving jaw plate. These components are the core elements of the jaw crusher. During operation, the moving jaw plate reciprocates along with the moving jaw, forming a specific angle with the fixed jaw plate, which in turn applies compressive force to crush the material. However, for those new to jaw crushers, the exact location and appearance of the jaw plates may not be immediately clear. To help clarify, we’ll now illustrate this with diagrams.

Analysis of Material for Metal Crusher Hammer Heads: How to Choose a Wear-Resistant Solution
In the field of automotive metal recycling, metal shredders are indispensable core equipment, and the hammer heads—critical components of these machines—affect equipment performance and service life directly through the materials chosen. Currently, the mainstream materials used for shredder hammer heads on the market include high-manganese steel, high-chromium cast iron, low-alloy steel, and composite materials made from cast steel combined with high-chromium cast iron. This article will provide an in-depth analysis of the characteristics of each material, helping you make an informed decision.
