When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It’s an inefficient practice that wastes energy, impacts product particle size distribution
The mill is designed to handle a total ball charge of 324.5 t at 100% loading with a percentage filling of 29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber.
mass of mill charge divided by mass flow rate. Ball mill is an efficient tool for grinding many materials into fine powder. A ball mill consists of a horizontal rotating cylinder containing cascading steel pebbles, balls, or rods. . grinder that grinds items into incredibly fine powders used for ceramics, cements, pyrotechnics, Get Price
Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed
