GRINDING ROLLS FOR VERTICAL MILLS IN THE CEMENT INDUSTRY
The operating parameters of vertical mills are seldom altered once optimum productivity is established. But efficiency improvements – and therefore cost savings – can still be achieved with developments in metallurgy of the grinding element.Improved metallurgy of Grinding Rolls
Vega Industries, in association with parent company AIA Engineering, has reviewed and improved the metallurgy of grinding rolls for the following mills:
- Monoblock rolls for Loesche and Polysius mills
- Segmented rolls for Atox and Polysius mills
- Segmented tables for Loesche, Polysius and Atox mills
- Grinding rings and Hollow balls for E mills
- Rolls and table segments of Raymond/CE mills
Abrasion is the most dominant factor in determining the working life of Vertical Mill grinding elements and The Group supplies three types of alloy to cope with the different abrasion conditions. In line with the trend towards ever larger mills, the company can produce individual castings of up to 20 metric tonnes in weight.
The grinding rolls are produced using the company's unique centrifugal casting facility, which ensures consistently high quality components. Its Sintercast products offer significant improvements in working life compared to components using conventional alloys.
Please contact your regional representative to find out more about the improved cost-effectiveness of The Groups grinding rolls. For more information about the company's other products, please return to the Cement Industries page.
