Cone crusher wearing parts material
As we all know, concave surface and mantle play the most important role in all the wearing parts of the cone crusher.
We know that the wear rate and short working time are big problems for sand mills, because they are directly involved in the grinding of stones. The frequent replacement of crusher spare parts not only shortens the effective running time of the sand and gravel production line, but also increases the production cost.
1. Stone powder content and stone humidity.
In the work of the crusher, if the stone powder content is high and the humidity is high, the material will easily adhere to the inner wall of concave and mantle during crushing, which will reduce the production efficiency of the crusher. In severe cases, it will also corrode concave and mantle. Reduce the service life of the crusher.
When the stone powder content of the material is high, it must be passed through a sieve before crushing, so that too much fine powder can be avoided during crushing; when the material has high humidity, measures should be taken to reduce the moisture content before crushing, such as mechanical drying. Measures such as drying or natural drying.
2. The hardness and particle size of the stone.
The hardness of the material is different, and the degree of wear on concave and mantle is also different. The higher the hardness of the material, the greater the impact load that the concave and mantle bear during the production process, which will reduce the service life of the crusher. In addition to the hardness of the material, it will affect the life, and the particle size of the material will also affect it. The larger the particle size of the material inside the cavity, the more severe the wear of the liner, which will reduce the service life of the crusher.
3. Feeding method.
The feeding method of the cone crusher will also affect the service life of concave and mantle. If the feeding device of the crusher is improperly installed or there is too much material when feeding, it will cause the crusher to feed unevenly and cause the crushing The internal material is blocked, which makes concave and mantle bear too much pressure, thereby increasing the wear of the ore on the inner wall, damaging the liner, and reducing the service life.
4. The weight of mantle and concave itself.
The above three points are all external factors. The most important factor affecting concave and mantle is its own quality. At present, the raw materials of concave and mantle of the market crusher are made of high manganese steel and wear-resistant parts. The surface has high requirements, and no cracks and casting defects that affect the performance are not allowed. With the development of science and technology, the performance of wear-resistant materials has been continuously improved. It is necessary to choose materials that can maintain their original toughness under impact.
