rotary drying machine Rotary dryer is a kind of fertilizer units used for drying coal powder, slag, clay stone and fertilizer, etc. It can be used individually or matched with other fertilizer equipment. Characteristics of Rotary Dryer 1. Rotary dryer, also known as drum dryer, is widely used for drying materials in cement industry, mineral industry, building material industry, chemical industry, food industry, fertilizer industry, etc. 2. Our rotary dryer is made up of rotary body, lifting blade, driving device, supporting device and sealing ring. 3. It has the features of rational structure, high efficiency, low energy consumption, reliable performance and easy operation, and so on. 4. The feeding device and discharging device are equipped with thermocouple, so the temperature change of the feeding end and discharging end of the rotary dryer can be clearly showed through the thermometer. This assists users in controlling the temperature inside rotary dryer at 350-380°. Operating Principle of Rotary Dryer Heat source of our rotary dryer comes from combustion apparatus. Our rotary dryer adopts counter flow type heating mode and the heating air supply goes into the dryer through discharge end. The materials to be dried enter the oblique rotary dryer through feed box and are pushed to the back of the drum by spiral shoveling plate. On one hand, they flow to the rear due to gravity and rotary force. On the other hand, they are shoveled up repeatedly by shoveling plate, sent to the upper end and then fell down. This makes the materials fully exchange with the hot air and gradually the moisture in the materials are dried.
