Principle of Work
Hot air enters into stiring and crushing and drying chamber from the bottom of drier with suitable atomizing speed. It exerts strong shearing, blowing, floating and rotating effect to raw material. Therefore raw material is granulated through centrifuge, shearing, impacting and friction effect. It strengthens the process of heat exchange. At the bottom of drier, the large and damp granule is cmshed under the action of stirrer and the granule that is small in particle and contain less moisture will lift accompanied with revolving air
stream. During the period of lift, it is dried further. Because gas and solid two phases flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phases is large, so it strengthens the process of heat exchange.
Therefore the machine has strong drying capacity.

Features
1.Because the raw material particulate exists in high dispersing state caused by centrifuge, shearing, impacting and rubbing effect, Moreover the relative velocity between solid and gas phases is high, SO it strengthens the process of heat exchange. Therefore the machine has strong drying capacity;
2.Dry gas enters into the bottom of drier and produces strong rotating air stream that exerts strong rushing effect to raw material on the wall, therefore the phenomenon of adhesive wall is removed;
3.At the bottom of drier, where is high temperature area, heat sensitivity raw material can not contact with heat surface directly, therefore it solves the carbonized and changed color problems of heat sensitivity raw material;
4.Because gas speed at circle inside the drying chamber is high and the staying time of raw material is short, high efficiency and quick speed can be realized. It is possible for small equipment to carry out large-scale production;
5.There are rotational flow pieces inside the drying chamber. It is used to control the moisture and granule of raw material to the needed level.
