Micro powder filter cake air swept rotary dryer is a kind of drying system specially designed for super fine micro powder and filter cake materials after wet grinding process. Feeding moisture ranges from 15% to 55%. Moisture of final product from Micro powder filter cake air swept rotary dryer can be reduced to lower than 1% one time. Typical raw materials contain feldspar, potash feldspar, soda feldspar, nepheline, calcium hydroxide, slaked lime, powder, zirconia, aluminium hydroxide and filter cake calcium mineral material. Materials are forced to flow out of dryer along with airflow. High speed air swept dispersing blade will form vortex which will improve drying effect. Micro powder fliter cake air swept dryer is featured in low emission, less energy consumption, less pollution and low running cost. Compared with traditional micro powder drying equipment, Hengyang air swept dryer can effectively save cost and holds better drying effect. Owing to great profit it can bring, Hengyang Micro powder filter cake air swept rotary dryer enjoys great popularity among different customers.
Wet materials (super fine powder or filtered cake after pressing) are continuously sent to air swept dryer. In first-level drying chamber, materials will enter vortex generator with hot air and form boiling state airflow. Materials are dispersed, dehydrated and dried. Following, materials enter second drying chamber where moisture is furthur evaporated according to curve. After that, materials will enter third drying chamber for slow-speed drying. Air swept blades set inside dryer drum will lift and stir raw materials and make materials mix with airflow. The contact surface between materials and airflow is enlarged so that improve drying speed and drying uniformity. Final dried products hold stable moisture. Final moisture can be reduced to lower than 1% one time. At present, Micro powder filter cake air swept rotary dryer has been widely applied in Hunan, Henan, Shanxi and many oversea projects. Customers are satisfied with final product quality and drying effect.
