Analysis of material flow and consumption in cement
Part of the raw meal at the bottom of silo is conveyed to the side silo catcher, and then elevated to the upper end of the silo by a lift dump. This implies that the raw meal homogenization process will take place again. Download : Download full-size image; Fig. 2. Mass flows in raw meal blending and silo storage.
