1. Introduction. Air-swept meal ball mills introduced by the cement mill manufacturers F.L.Smidth ® (Smidth 2002) Polysius ® (Polysius 2002) and KHD Humboldt Wedag® are the most commonly used ones.KHD Humboldt Wedag® manufactured fully air-swept meal mills which have two compartments used for drying and grinding processes.

Air-Swept Ball Mill Ball mill is a traditional coal pulverizer machine which has been widely used since it was invented. In the cement plant the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5% while that of coal is 1.5% ~ 4.0%.
The mill may be run as a grate discharge mill and as an air-swept mill. 2.1. Air-swept mill configuration The flowsheet of our fine grinding circuit together with operating parameters to be controlled is shown on Fig. 1. A screw feeder supplies the new material to the ball mill.
1. Air swept ball mill is an efficient tool for grinding many materials into fine powder. 2. The Air swept ball mill is used to grind many kinds of mine and other materials or to select the mine. 3. Air swept ball mill is widely used in building material and chemical industry. 4. There are two ways of grinding: The dry way and the wet way. 5.
