Introduce grinder blade wear and durability


    Under normal circumstances, the wear and durability of crusher blades are related to the efficiency, quality and cost of crushing. Therefore, when using crusher blades, it must be operated according to the regulations. Mainly reflected in the following areas:


    Hard spots are carbide nitride oxides and intermetallic compounds, etc., can be grooved on the outer surface of the tool, which is the blade wear. This means that the overall level of metal cutting in China is not high. In addition to the tool, the workpiece In addition to the nature of the material itself, temperature is the most important factor affecting diffusion wear. The particles in the cutting act as a plough on the tool. Generally, air does not easily enter the blade contact area, and oxidation wear is most likely to occur on the primary and secondary cutting edges. The formation of the border area reduces CO in the binder phase and reduces the bond strength of the hard phase in the cemented carbide. It can meet the premise of occurrence of cold welding. The normal working speed of the high-speed steel crushing blade and the working speed of the carbide blade are low. Therefore, it is imminent to deepen the structural adjustment of the crusher blade industry. Only in this way can domestic tools increase their competitiveness in the market. Diffusion wear is often associated with cold welding wear and abrasive wear. At this time, the wear rate is high.
