As we all know, wear and tear is unavoidable in the use of crushers. Below, we will briefly introduce the vulnerable parts of crushing equipment and their material selection.

First, let’s distinguish between the concepts of friction and wear: Friction refers to the relative motion between two contacting objects; wear refers to the material loss that occurs during friction.

The most vulnerable part of a jaw crusher is the jaw plate. This is because during operation, the jaw plate experiences short-range sliding with the material, leading to chipping and the formation of metal debris. Another issue is the repeated deformation of the jaw plate due to material compression, which over time causes metal loss. Jaw crusher jaw plates are typically made of materials with high hardness and toughness to resist compressive wear and prevent impact fatigue. Different jaw crusher sizes and feed particle sizes result in varying compressive and impact forces on the jaw plates. Therefore, the material selection for the jaw plates varies depending on the model and the impact and excavation stress during installation. Generally, large jaw crushers use high-manganese steel or high-manganese alloy steel, while smaller jaw crushers can use medium-carbon multi-alloy steel or medium-manganese alloy steel.

The hammers of a hammer crusher repeatedly contact and impact the surface of the material being crushed during operation, accelerating the wear rate of the hammer’s metal surface. High-manganese steel is generally selected as the raw material for the hammers based on the material characteristics.

The quality of mechanical equipment is a crucial guarantee for the normal operation of a production line. Due to the high-intensity working conditions, crushers face a significant challenge to their quality. Xinshengrun prioritizes product quality, strictly controlling the selection of materials for its crushing equipment, laying a solid foundation for manufacturing high-quality crushing equipment. Quality is life; our company’s jaw crushers, impact crushers, and other crushing series products conquer the market with their quality.
