The crusher liner plate is an important parts with the production efficiency of improving the crusher and reducing the cost of use. Therefore, the quality of the lining plate is particularly important. Let's introduce the purchase skills of this type of liner
1. The material of the high manganese steel crusher liner plate
The crusher liner plate should have the characteristics of the surface of the shock load and still maintain the original toughness of its internal metal in order to be used as a wear -resistant material commonly used in crusher. The existing most abrasion -resistant material is carbides contained in martensite matrix. The hardest in carbides is chromium compounds, such as high -chromium cast iron materials.
2. The shape of the liner plate
The test shows that under the same conditions, the crusher liner on the smooth surface can increase the productivity by about 40%compared with the tooth liner plate, and the service life can be increased by about 50%. However, the broken force increased by about 15%, and the particle size of the product was not controlled, and the power consumption consumed slightly. Therefore, for the broken layer -like materials, it is not advisable to use a smooth liner plate when the product is high. For materials with strong crushing and corrosive, in order to extend the service life of the wear -resistant lining plate, it can be used to use it.
3. The surface roughness of the lining plate
The requirements of the surface roughness of the lining plate are related to the contact stress on the surface of the lining plate. When the surface hardness of the contact stress or the surface of the lining plate is generally low, the roughness of the surface of the lining plate is low.
4. Material material
The greater the grain size of the material, the higher the hardness, and the more serious the metal material lining is worn; the same required material that needs to be broken, which contains the poor grinding of free silicon dioxide, and the lining plate is more serious.
5. The parameters of the crusher
Considering the diameter, speed, and filling rate of the crusher.
The above is the purchase skills of the high manganese steel crusher liner plate . Its quality is related to the efficiency of the crusher. Everyone must grasp the quality when buying, and choose the "good" lining board with good intentions.
