Answer-7 The number of cyclone stages in a preheater system largely determines the system heat efficiency heat of the exit gas leaving the system In modern practice most of the kiln gases from a preheater or precalciner system are used for drying in both the raw mill and the coal mill
In all ore dressing and milling Operations including flotation cyanidation gravity concentration and amalgamation the Working Principle is to crush and grind often with rob mill ball mills the ore in order to liberate the minerals In the chemical and process industries grinding is an important step in preparing raw materials for subsequent treatment
Roller mills The grinding action employs much greater stress on the material than in a ball mill and is therefore more efficient Energy consumption is typically half that of a ball mill However the narrowness of the particle size distribution of the cement is problematic and
A rawmill is the equipment used to grind raw materials into rawmix during the manufacture of cement Rawmix is then fed to a cement kiln which transforms it into clinker which is then ground to make cement in the cement mill The rawmilling stage of the process effectively defines the chemistry of the finished cement and has a large effect upon the efficiency of the whole manufacturing process
