Basic Knowledge about the Attrition of Jaw Crusher

If we can better understand the basic knowledge about the attrition of the jaw crusher, we can better use the jaw crusher.
First, we should know the reasons of the attrition of the jaw plate. The materials are repeatedly squeezed and the tooth plate is chipped. On the surface of the tooth plate area, the jaw plate may be easily to form the microcrack at the prominent part. The microcrack of the tooth plate of the crusher continuously expands to the connection, which will cause the falling off of the surface metal and form the debris. The materials are repeatedly squeezed, which causes the local crack or flips of the metal materials of the tooth plate. The fragmentation or flips part will form the debris together with the extruded materials. The materials slide with short stroke related to the tooth plate. The materials will cut the plate and form the debris.
How to solve the attrition of the jaw plate of the jaw crusher? From the above reasons, we can know that the affecting factors of the attrition of the jaw plate include the properties of the materials, the operating parameters and the material of the jaw plate. Since the specifications and the size of the jaw crusher are different and the feeding size is also different, the extrusion and impact force on the tooth plate and the materials selection are different. When you select the material of the jaw plate, Henan Hongxing Mining Machinery reminded that you should follow the two principles. First, you should select the materials with high hardness to resist extrusion and the micro-cutting failure. Second, you should select the materials with enough toughness to resist chipping impact fatigue failure.
Under normal circumstances, the squeeze pressure of the large and medium-sized jaw crusher is large. Beside the anti-extrusion and the anti-sliding cutting of the materials, you should also consider the impact force and bending stresses during the impact process. Therefore, for the large tooth plate, you should choose the materials with high toughness and good comprehensive performance. You can choose the high manganese steel or the alloy high-manganese steel. On the contrary, for the tooth plate of the small jaw crusher, you can choose the material with high hardness and appropriate toughness to improve the ability to resist extrusion resistance and micro-cutting.
