XSZ series high speed roatng drier is developed by our factory, and its’ technology is based on advance technology adored. The machine is including many superiority, such as reasonable design, compact stuction, windy utilization, great productive capacity, good quality, high effect and save energy. Drying, grinding and sieve are completed in one equipment in once time. It eliminate pollution and the technology is reached international advance level.

Hot in enters into stirring 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 great exchange. At the bottom of drier, the large and damp granule is crushed under the action of stirrer and the granule that is small in partical and contain less moisture will lift accompainied with revolving air stream. During the period of lift, it is dried further. Because gas and solid two phase flow in rotating and the intertia of solid phase is more than that of gas and the relative velocity between solid and gas phase is large, so it strengthens the process of heat exchange. Therefore the machine has strong drying capacity.
