Fly ash separator is mainly used as a classification equipment in the coal powder preparation (grinding) system of cement plants. This product integrates the plane eddy current classification principle of the O-Sepa separator and the finished product collection method of the cyclone dust removal. The fly ash separator system has a simple configuration, flexible process layout, high powder selection efficiency, and significant energy-saving effect. It is a new method and new way for cement companies to improve product quality under the new situation.
Working Principle
The variable speed motor drives the main shaft to rotate through the transmission device. The material enters the center of the powder selection chamber through the feed port located at the upper part of the powder selection chamber, and then falls to the scattering plate rotating with the main shaft at the lower part of the powder selection chamber through a special drop pipe. The logistics is evenly scattered around under the action of the high-speed rotating scattering plate. The high-speed swirling airflow generated by the external circulation fan disperses the high-speed scattering material. The coarse and heavy particles (d>150μm) in the material are thrown to the inner wall of the powder selection chamber by the inertial centrifugal force. After the collision, they lose kinetic energy and slide down along the wall to fall into the coarse powder cone. The rest of the material is blown up by the rotating airflow and continues to rise. When passing through the large wind blade area, some coarse particles are sorted out and fall into the coarse powder cone.
The material (d<150μm) sorted twice by the scattering plate and the large wind blade continues to rise and enter the classification area: the plane vortex classification area. The dust-laden airflow is further selected out of the coarse powder that does not meet the requirements of the finished product under the strong and stable plane vortex formed by the rotating cage rotor. Because the inertial centrifugal force generated by the coarse particles is greater than the centripetal suction of the vortex, the coarse particles are thrown to the surrounding vertical guide blades, lose kinetic energy after impact, fall into the medium coarse powder cone, and are discharged through the medium coarse powder air lock valve. The fine powder that meets the requirements (d<60mm) passes through the cage and enters its interior, and enters the separator arranged around the powder selection chamber with the circulating air, and is collected to form the finished fine powder.
