One of three SAG mills with m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be adapted for fine grinding by substituting a bowl ...
Individual large air swept Vertical Mills are preferred over ball mills for better grinding efficiency and to get an advantage in power consumption. Cement raw material is the mixture of mainly Limestone other constituent such Iron oxide, Shale etc. having different moisture contain depending on composition deposit.
Crushing Plant Flowsheet DesignLayout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2in. size, but they work much more efficiently if their feed is ½ in. or less.
