Vertocal raw mill process in cement plant with image. Aug 13 2015 183 McInnis has installed a vertical raw mill for raw meal preparation and two identical vertical finish mills 8400 tpd with highefficiency separators between the 120000 mt of clinker storage and the 120000 mt of cement
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
In this study the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be 61.5 and 16.4 respectively.
