Some materials should avoid direct contact with the material and component materials have corrosion requirements, generally, this material are made of austenitic stainless steel, while the austenitic stainless steel surface hardness is lower comparing with polyhedral; if adopt austenitic stainless steel to make grinder pieces, it is easy to produce metal particles. However, an important way to reduce the wear particles is to increase the hardness of the grinder pieces of material, the lower the carbon content in the material, correspondingly, the hardness is also low, and high-carbon material can easily rust. Therefore, we have to pay attention to deal with good material corrosion and hardness contradiction in the choice of the materials of grinder pieces.
Dry crusher relies on high-speed rotation of the rotor role; particles between the rotor and the stator is crushed by the shear forces or the frequent grinding rotation between the member and fasteners; such works often generate the phenomenon of the insoluble impurities and metal particles contamination in the pulverizing process due to the badly wear of the material directly contact spare parts.
In order to properly handle the above contradictions, it is necessary to analysis the contradictions in the primary and secondary; shredders pieces wear resistance is the main, ensure that corrosion and wear resistance under the premise. As for dry grinding equipment, such as ball mill, materials chloride ion in the dry material under normal circumstances is almost no precipitation, that is, intergranular corrosion in the material probability is very low, therefore, the material of grinder pieces must be similar to the lower hardness 316L low carbon stainless steel.
Therefore, I suggest a three-pronged approach to select the grinder pieces of material:
1, high alloy nickel chromium steel.
2.Austenitic stainless steel.
3, the hard ceramic.Henan Hongxing Mining Machinery Co., Ltd is a large-sized impactor equipment, raw material mill manufacturer, and the mining equipment we researched and developed with great concentration plays an active role in the mining and ore beneficiation industry and is one of the indispensable mining crushing equipment in the mining industry.
