At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.
DERBA MIDROC CEMENT PLC is proposing to establish a green field cement plant of capacity 5,600 tonnes per day (tpd) of clinker (cement capacity of 7000 tpd) based on Derba limestone deposit in Ethiopia.
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
