Selection of crusher hammer

Key factors and suggestions to consider when choosing a crusher hammer.

1. Material selection
   The material of the crusher hammer is the primary factor that determines its service life and crushing effect. Common materials include high manganese steel, alloy steel, high chromium cast iron, etc.
   High manganese steel: has good toughness and wear resistance, suitable for crushing materials with medium hardness or below, such as limestone, coal, etc.
   Alloy steel: By adding other alloy elements such as nickel, molybdenum, vanadium, etc., the hardness and wear resistance are improved, suitable for crushing hard materials.
   High chromium cast iron: has extremely high wear resistance, suitable for crushing high hardness materials, such as basalt, iron ore, etc.
2. Hammer structure
   The structural design of the crusher hammer is equally important for the crushing effect and service life. Common structures include flat head type, round head type, pointed head type, etc.
   Flat head type: suitable for coarse crushing, large crushing force, but faster wear.
   Round head type: suitable for medium and fine crushing, uniform crushing effect, relatively small wear.
   Pointed type: suitable for fine crushing, high crushing accuracy, but easy to damage.
3. Hammer weight and size
   The weight and size of the hammer should be selected according to the model of the crusher and the nature of the crushed material. A hammer that is too heavy or too large will increase the load of the crusher and reduce the crushing efficiency; a hammer that is too light or too small cannot provide sufficient crushing force.
4. Surface treatment
   In order to improve the wear resistance and impact resistance of the hammer, surface treatment technologies such as heat treatment, surface quenching, and plating are widely used.
   Heat treatment: By changing the internal structure of the metal, the hardness and toughness are improved.
   Surface quenching: A hardened layer is formed on the surface of the hammer to improve wear resistance.
   Plating: A layer of wear-resistant material such as chromium, nickel, etc. is plated on the surface of the hammer.
5. Manufacturers and brands
   Choosing reputable manufacturers and brands can ensure the quality and after-sales service of the hammer. It is recommended to choose manufacturers with rich experience, good reputation and high-quality service.
6. Economic Analysis
   When choosing a hammer head, not only the initial purchase cost should be considered, but also long-term economic factors such as its service life, maintenance cost and replacement frequency should be considered.

The selection of crusher hammers is a process that takes into account many factors. By rationally selecting the material, structure, weight, size and surface treatment of the hammer, combined with the reputation of the manufacturer and the economic analysis of the product, the efficient operation and long-term stable production of the crusher can be ensured. In practical applications, the most suitable crusher hammer should be selected according to the specific crushing task and material characteristics to achieve the best crushing effect and economic benefits.
