Information
1. In terms of hardness: the high-quality medium-speed coal mill grinding roller adopts high-chromium cast iron wear-resistant material, and the Rockwell hardness (HRC) is higher than 65 °C, which can play a good wear-resistant effect during operation, improve. The service life of the product is the most important point when purchasing a medium-speed coal mill roller.
2. In terms of technology: the high-chromium grinding roller used in the vertical mill adopts "one-type multi-casting", which saves modeling materials and man-hours, improves labor conditions and improves production efficiency.
3. Look at the impact toughness value. Another important index is the toughness value. The toughness value reaches 7J (Joules). This standard is to make the grinding roller of the medium-speed coal mill not easy to crack during long-term operation.
In general, the wear surface of the high-quality vertical grinding roller/roller sleeve is uniform and smooth, and there are no pits and grooves. After long-term operation, there are no peeling, falling blocks, cracks and other phenomena.
