The jaw crusher has the characteristics of simple structure, low manufacturing cost, convenient maintenance, reliable operation and easy configuration.
1. Material hardness
The hardness of the material has an important influence on the wear of the jaw plate. Under the same other conditions, materials with high hardness are more likely to be pressed into the surface of the base of the jaw plate than those with low hardness, resulting in furrow wear.
2. Jaw plate material
The wear resistance of the jaw plate material directly determines the service life of the jaw plate. Although high-manganese steel is partially replaced by other steel grades under the conditions of low-stress and medium-stress impact abrasive wear, it still occupies an important position in wear-resistant materials due to its low production process requirements and wide source of raw materials.
3. Movement track of movable jaw
The movement trajectory of the movable jaw has an important influence on the performance of the jaw crusher. The production capacity, specific power consumption, steel consumption (jaw plate wear) and quality of crushed products of jaw crushers are all directly related to the movement trajectory. Taking the compound swing jaw crusher as an example, the jaw plate of the compound swing jaw crusher usually has the following wear characteristics after production and use: the wear of the fixed jaw plate mainly occurs in the lower part of the jaw plate, and the discharge port wears the most, The movable jaw wears the most in the middle.
