Dynamic-Static Combined Rotary Classifier——Dynamic-Static Combined Rotary Classifier
The new Dynamic-Static Combined Rotary Classifier has been developed independently and successfully winning the national patent (Patent Name: One kind of Dynamic-Static Combined Rotary Classifier and Sealing Ring; Patent Number: ZL2008 2 0123001.9) through the cooperation with the national key laboratory.
The new generation product has small volume, low power consumption and excellent separation characteristics with larger and more flexible adjustment range for coal powder fineness and finer fineness (R90=2—40%). Meanwhile, the shell and the blade of the classifier have smaller wear and longer service life.
●Scope of Application
The Dynamic-Static Combined Rotary Classifier complies with the requirements of coal powder fineness by related industries and better suits the grinding of anthracite and lean coal for thermal power system. The fineness and the uniformity of coal powder can facilitate staged combustion of the generating unit and the reduction of oxygen supply in the main combustion zone to achieve the goal of controlling and reducing the emission of NOX.
