Excellence in coal grinding Some vertical mills use freeroaming balls instead of tires. These balls are hold in place by an upper and lower ring which provide the grinding pressure and the material is ground in between. Magotteaux supplies those hollow balls in various grades of wear resisting alloys. The maximum ball size is 1,130 mm OD x 150 mm thick.
20/9/2016#0183;#32;The use of ball mills for wet grinding of various materials is a very common and efficient process. Ball mills are used to grind raw materials, ores and minerals (like lime or limestone) for flue desulphurization, coal and several other raw materials. Ball mills can be of two types, based on the different ways materials []
Our ATOX#174; coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent. For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent.
designed for use with ball mills that grind coal, petcoke or charcoal. It is an energyefficient and wellproven solution which incorporates the experience attained from over 1500 high efficiency dynamic air separators supplied by FL in grinding applications. The RTKM separator is the obvious choice for new coalgrinding ball mills.
