Limestone Grinder Roll has made vertical mills popularized and applied in the cement industry. At the same time, the wear resistance of cement grinding rollers and grinding discs used in vertical mills has also attracted the attention of cement manufacturers in the Middle East.
Due to its special working conditions, cement grinding rollers will cause serious wear on the roller surface. All cement grinding rollers and grinding disc linings are generally made of integral wear-resistant alloy casting (high-chromium cast iron or nickel-hard cast iron) or composite wear-resistant surfacing welding. technology to improve the wear resistance and prolong the service life of cement grinding rollers and grinding discs.
The metal type cement grinding roller not only overcomes the shortcomings of ordinary roller sleeves, which are not wear-resistant and easy to crack, but also prolongs the service life of the product and improves the hourly output of the cement grinding roller.
As a result, the economic cost is reduced for consumers and the production efficiency is improved, so it has been unanimously recognized and praised by customers.
Not only that, the cement grinding roller cast by the new process has a wider range of application scenarios, and the products are also widely used in mining, building materials, and coal industries.
The innovation of cement grinding roller not only brings good news to the machinery industry, but also opens a new milestone for the foundry industry.
Unique advantages of Limestone Grinder Roll
The cement grinding roller adopts “one-type multi-casting” to save man-hours and modeling materials, improve productivity and improve working conditions.
2. Quality aspects
The cement grinding roller is made of high-chromium cast iron wear-resistant material, and the heat treatment adopts the tempering and quenching process, which can make the Rockwell hardness HRC higher than 65, and at the same time make the grinding roller have better wear resistance and toughness.
3. Service life
The tire-shaped design is adopted, which can be turned over for use, which improves the utilization rate of the roller sleeve. The service life of the high-chromium grinding roller is more than 1.5 times that of the ordinary roller sleeve.
4. Economic aspects
Large-scale high-chromium cast iron grinding rolls are cheap to manufacture. The high output per hour can increase the production output, thereby increasing economic benefits. Suzhou Runda also recycles used roller sleeves to reduce economic costs.
