In industries such as mining, construction, railways, and highways, crushers are core equipment, mainly used for crushing medium and medium-hardness or above ores and rocks. Wear-resistant parts of crushers, especially those in cone crushers, concave and mantle have a decisive impact on the crushing effect. High-quality wear-resistant parts can not only improve crushing efficiency but also extend service life and reduce maintenance costs. There are many factors that affect the performance and life of these wear-resistant parts, mainly including the composition, hardness, and humidity of the stones and the quality of the wear-resistant parts themselves.
Stone Composition
The types of crushed stones are diverse, and the particle size varies. They usually contain a lot of fine powder. The higher the fine powder content, the greater the impact on the crushing capacity, because during the crushing process, the fine powder is easily attached during transportation and crushing, thus affecting the equipment's working efficiency. If there is too much fine powder in the material, it is recommended to screen it before crushing to remove excess fine powder, which can effectively avoid interference with the crusher's performance. Impurities in the material will also affect the crushing effect, so when choosing concave and mantle it is necessary to consider the specific characteristics of the material to choose more suitable wear-resistant parts for the crusher.
Stone Hardness
The hardness of the material is an important factor affecting the crushing effect. Materials with higher hardness are usually more difficult to crush and cause concave and mantle more wear and tear. As the crusher runs, hard materials will increase the wear of wear-resistant parts, thereby reducing crushing capacity and work efficiency. For harder ores, such as dense rocks, wear-resistant parts with stronger wear resistance and higher quality should be selected, such as the Mn13 and Mn18 materials of cone crusher fixed and moving cone liners provided by Duma Machinery, which can effectively meet the crushing needs of materials with higher hardness.
Stone Humidity
Wet stones are more likely to adhere to concave and mantle during crushing, forming material accumulation. Adhering materials will lead to a decrease in the equipment's crushing capacity and increase the wear of parts, thus affecting their service life. Therefore, when processing materials with high water content, special attention should be paid to preventing adhesion to maintain the normal operation of the equipment.
The above factors are external influences, but concave and mantle its own quality is still a key determining factor. A high-quality crusher wear-resistant part should have a casting surface that meets strict quality requirements, without cracks, inclusions, sand inclusions, or pores, ensuring higher wear resistance and service life. Duma Machinery Foundry strictly implements standardized operations in the stages of molding, casting, heat treatment, and machining to ensure that each wear-resistant part can maximize its performance and extend its service life.
