In the cement industry, a ball mill for this application is called a Preliminator mill. Con grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker.
The Tube Mill, used for finish grinding of cement, but also for rawmix and coal, was first patented in 1891 (Meyer Joseph Davidsen, a Dane living in Paris) and subsequently manufactured in 1893 by FLS. The mill had many features that have continued into modern designs. The tube was of welded mild steel plate, of length 35 times the diameter.
right mill for the specified duty is the most critical for circuit design, since it has the highest capital and operating costs. Bond method has been used for ball mill selection in both mineral and cement industry for 50 years. It is basically rely on determination of grindability of material in a specified laboratory mill.
At a minimum of 100mm thick, each ten square metres will use a cubic metre, roughly 2¼ tonnes, of concrete/mortar, and as a cementbased material, it will be going off from the moment it is prepared, Consequently, this method best suits those gangs confident of laying flags accurately and rapidly.
