GRINDING ELEMENTS FOR VERTICAL MILLS IN THE POWER GENERATION INDUSTRY
The operating limits of vertical mills are rarely altered once optimum productivity is established. But new developments in metallurgy of the grinding element mean that efficiency improvements and therefore cost savings can still be achieved.
Vega Industries, with its parent company AIA Engineering, has reviewed and improved the alloy composition of grinding rolls for the following mills:
- Monoblock rolls for Loeche and Polysius mills
- Segmented rolls for Atox and Polysius mills
- Segmented tables for Loeche, Polysius and Atox mills
- Grinding rings and Hollow balls for E mills
- Rolls and table segments of Raymond/CE mills
Abrasion is probably the single most important factor in determining the working life of Vertical Mill grinding elements and The Group supplies three types of alloy to cope with 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 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 Power Generation Industries page.
