Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation.A ball grinding mill consists of a hollow cylindrical shell that is partially filled with balls. The grinding media is the steel balls that can reduce the size of materials to a fine powder. Grinding can be carried out either wet or dry for various ores and other materials. This industrial mill is.Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Grinding media consists balls of 3-4 sizes (60mm-30mm) in designed proportions with large sizes in feed end and small sizes in discharge end.
Primary Ball mill controls are Mill drive power or mill differential pressure to control mill feed rate. Mill Sound level to control filling level inside mill with feed rate. Mill outlet gas temperature. Mill outlet material temperature. Cement temperature. Outlet gas flow determined from mill inlet and outlet drafts or flow meters installed.Nov 10, 2012 Ball mills are predominantly used machines for grinding in the cement . Chambers I II calculated as equivalent to degree of filling of 22 21 respectively. detailed.The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).
Circuit. Typically, ball mills are used for grinding the cement clinkers because of their mechanical robustness. Fig. 2 illus-trates a ball mill.
