Swiss Tower Mills Minerals AG (STM) was founded in 2012 to introduce the well proven fine grinding technology of industrial minerals to the mining industry. Today more than 200 grinding mills are operating today to grind industrial minerals with truly minimized energy requirements; over 10 units are currently operating in the hard rock mineral processing industry. STM’s technology enables the mining industry to profit from more than 40 years of development and operational experience in fine and ultra-fine grinding. In the meantime, the HIGmill™ has been accepted by the hard rock mineral processing market. Numerous tests have been successfully performed, both laboratory or on site. STM has received several orders from very small test and pilot mills, up to several large 5 MW HIGmills.
