Abstract
The invention discloses a mineral power calcining dehydration device and relates to productions of mineral power dehydration devices for semi-hydrated gypsum, cement plant clay and the like. A vertical and transverse fire cube structure is used so that the occupied area is reduced greatly, the heat-exchange area is increased and heat in fire cubes are absorbed fully by power. Additionally, by designs of a preheating chamber and an economizer on the tail portion, the heat utilization efficiency is increased and energy can be saved. Coal burns fully without black smoke so that the combustion efficiency is increased. Compared with other structure devices, the mineral powder calcining dehydration device can save 30 to 50 percent coal. The strength of gypsum is increased by at least 30 percent by using flash evaporation technique. By a combination of the mineral powder calcining dehydration device and electronic control technique, controlling temperature is accurate and the product quality is stable. The complete automatic production is achieved. No manual operations are permitted during the whole productive process so that labors are omitted, production cost is saved and the production efficiency is increased.
