At present, the mineral product main use dry rotary kiln, directly or indirectly heating mode of cylinder drying machine, electric oven, far infrared drying equipment and other machinery. But these equipment covers an area of big, big energy consumption, low utilization rate of hot operation, at the same time, the low degree of automatic operation of the equipment, drying product loss is big, in the process of drying cost is high, serious impact on the economic benefits of mill plant. At present, the drying technology has been developing rapidly, spray drying, fluidized bed drying, research and application of the airflow flash dryer has very wide range. According to the characteristics of mineral products, combined with new drying technology, and other industries in the drying technology is suitable for minerals is developed on the basis of efficient flash dryer, also known as the rotating quickly crushed air drying equipment.
