Crusher Blades are mainly used in various types of crusher equipment. The following is an introduction to their characteristics:
1、 Material characteristics
High hardness
Crusher Blades are typically made of materials with high hardness, such as high-quality alloy steel, high-speed steel, or hard alloys. High hardness enables the blade to withstand tremendous impact and friction forces, making it less likely to deform when crushing hard materials. For example, blades made of hard alloy can achieve a hardness of HRA89-92.5, which can effectively crush materials with high hardness such as ores and construction waste.
High strength and toughness
In addition to high hardness, the blade also needs to have good strength and toughness. This is to prevent the blade from breaking during operation. During the crushing process, the unevenness of the material and unpredictable impact forces may cause significant stress on the blade. For example, when crushing construction waste containing metal impurities, high-strength and tough blades can resist the damage caused by metal impact, ensuring the service life of the blades.
Good wear resistance
Due to the frequent contact between crusher blades and various materials for crushing operations, good wear resistance is one of their key characteristics. By special heat treatment processes or surface coating treatments, the blade can significantly improve its wear resistance. For example, blades treated with surface chrome plating can form a hard and wear-resistant layer, reducing the wear of the blade during friction with the material and extending its service life.
2、 Shape design
Diversified blade shapes
The blade shapes of Crusher Blades come in various designs, including flat blades, serrated blades, and hooked blades. Flat blade is suitable for general cutting and crushing of materials, such as crushing relatively soft materials such as wood and plastic. Sawtooth blades are more suitable for crushing fibrous or tough materials, and serrated edges can better grip and tear materials. Hook blade is mainly used to crush materials with block like or larger block like structures. Hook shaped blades can effectively hook and crush large blocks of materials.
Reasonable blade shape
The overall shape design of the blade is also important. Generally speaking, the shape of the blade will be customized according to the type of crusher and the characteristics of the crushed material. For example, the blades used in cone crushers are usually conical in shape, matching the shape of the crushing chamber of the cone crusher, which can better achieve extrusion and crushing of materials. The blades used in counterattack crushers may be in the form of plates or blocks, which break the material through counterattack action.
