The Limestone Grinding Mill grinding roller is the core equipment of the grinding material, but it also affects the frequent damage and replacement of the grinding roller due to the accumulation of materials and the nature of the material. However, if the purchase is not appropriate, not only will it not reach the previous grinding power, but it will also be damaged quickly. So how do you choose a high quality Limestone Grinding Mill roller? In addition to selecting the type of grinding roller that meets the model, pay attention to the following three points.
When selecting the grinding roller of the Limestone Grinding Mill, it is indispensable for the inspection of the manufacturing process. If there are small defects such as small cracks, shrinkage holes and transgranularity inside or outside the grinding roller sold by the supplier, we purchase such a grinding roller. When it is rejected, although it is less, it will reduce the performance of the grinding roller and even cause the grinding roller to break. Therefore, when purchasing, the grinding roller must be manufactured with reasonable casting and heat treatment processes. The development of a reasonable production process and strict quality inspection methods is a prerequisite for ensuring the performance of the grinding roller.
Generally, the grinding rolls are made of high manganese steel, high chromium cast iron and low carbon alloy steel. Among them, high manganese steel is commonly used in Limestone Grinding Mills, with high wear resistance, good toughness and good high temperature resistance. Its work hardening index is about 6 times higher than other materials, while high chromium cast iron has high corrosion resistance. However, it is imported into high-manganese steel in all aspects, and the low-carbon alloy steel is suitable for other milling equipment applications. Currently, this material is rarely used in China. Through the comparison of these three materials, the application of high manganese steel grinding roller should be purchased. It is not only specially made for grinding harder stone, but also cost-effective grinding roller.
The design of the Limestone Grinding Mill roller directly affects the future grinding work. Grinding rolls of different structures and geometries have different milling properties. The thicker the grinding roller of the Limestone Grinding Mill, the harder it is forged, and the worse its wear resistance. Of course, the design of the grinding roller is reasonable, not only can improve the service life, but also can fully grind the material, especially the structure of the grinding roller of the Limestone Grinding Mill is optimized to improve the utilization rate. Therefore, when purchasing, the structure of the grinding roller should be considered and analyzed.
