1、 The equipment is characterized by its compact frame, small size and large capacity.
2、 Low energy consumption per unit of product, powerful drying capacity.
3、 Short drying time(3-30s), also applicable for heat-sensitive materials.
The materials are fed into a drying-tube with small diameter, and accelerated by the hot hair at a high speed. suddenly, the materials rush into a thicker part of drying-tube by inertia. In movement, the speed of material particles is gradually decelerated until the speed is constant. Then the drying-tube diameter becomes much smaller again so that the particles are accelerated again. Through repeated alternation of acceleration and deceleration, a high efficiency of heat-transferring and mass-transferring is obtained so that the materials are dried instantly. At last, the dried product goes with the cyclone separator for gas-solid separation, and dust is collected effectively by the bag filter.
As to the materials of high drying requirement (Dried product containing water: 0.5~0.01％), pulsed air dryer is applied to drying for the second time .
Air-flow with materials goes into the cyclone dryer in the tangential direction, then moves in a spiral along the inner wall of the dryer. The materials are evenly distributed in the air-flow with swivel disturbance so that heat-transferring area is enlarged, drying time is lengthened and drying process is enhanced.
This type of equipment is made for mining, chemical industry, light industries for drying both particles and power materials. Finished product is powder.
According to features of material, bag collector or wet spraying dust cleaner can be used as 2nd phase dust cleaning equipment.
Steam, electricity or heat air furnace heating can be selected as heat source according to factory conditions and allowed temperature of the material.
