A vertical roller mill has been installed in a Canadian cement plant for the pregrinding of Portland cement clinker. It is the first application of this type of technology in the Western Hemisphere.
If HPGRs are operated correctly, ball mills can be downsized and use smaller grinding media, which substantially reduces steel ball consumption, increases the grinding efficiency and lowers operating costs of the milling substantially. The use of HPGR technology also promotes micro fracturing, which can expose minerals encased or locked within a particular ore.
