Fuel grinding systems in cement plants require adequate protection against the hazards originated by potential fires and dust explosions. Coal Mill Safety takes ICR readers through the design of the part of the coal and petcoke grinding system to highlight the design required to operate a safe fuel grinding system.
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50-100mm steel balls are used in the coarse grinding chamber, φ20-50mm steel balls are used in the fine grinding chamber.
The Polysius-Aerofall-mill as a drying-grinding plant. The Polysius-Aerofall-mill which is predominantly used for autogenous grinding in the preparation or ores, is now increasingly employed in the cement industry, particularly for drying-grinding of cement raw material. The Polysius-Aerofall-mill is a short tube mill with a large diameter.
The basic chemistry of the cement manufacturing process begins with calcination, the decomposition of calcium carbonate (CaCO 3) at about 900 °C to leave calcium oxide (CaO, lime) and liberate gaseous carbon dioxide (CO 2).This is followed by the clinkering process in which the calcium oxide reacts at high temperature (typically …
