The unique grinding technology, which Swiss Tower Mills Minerals AG offers for the mineral processing industries, has been well proven over more than 40 years in the industrial mineral segment: over 200 fine and ultrafine grinding mills are in operation, with a total installed power of over 300 MW.
"The control of the operation of semi autogeneous grinding (SAG) mills is mainly achieved through adjustments of feed rate, water addition and speed of rotation. With the introduction of image based sensors it is possible to have online measurements of the size distribution of the ore feeding a SAG mill.
Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling. Each of these mill environments presents a unique environment for grinding media, requiring the appliion of specific physical and chemical properties for optimum grinding media performance. The .
