Coal ash is a kind of industrial waste residue. Some studies show that more fine the coal ash is, higher activity the coal ash release,and more useful the coal ash finess is. It has been proven very effective as a cement performance enhancer which improved strength, permeablility and corrosion resistance properties. Whats more, it also can be widely used in baking free brick, cement plant, ceramics, glass, steel,plastic,ruber and highway foundation project. So the coal ash fine grinding industry spring up, to expand and develop widely coal ash application area.

The classifier drives the impellers on the tray to rotate through speed adjusting motor, so that powder can be separated. The standard particles will enter cyclone collector. After being separated from the air flow, powder will be collected. Substandard particles will be thrown to the outside wall, to be separated from the air flow. Heavy powder will fall into the grinding chamber to regrind due to self gravity. Powder making production line: Materials first enter jaw crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually.

Operation principle of main unit: Main unit runs with the central shaft that is driven by a decelerator. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a swing support. The grinding roller not only rotates around the central axle and grinding roller, but also rotates around its own axle due to the friction. There is pallet knife system at bottom of quincunx stand. The pallet knife system is under the grinding roller. With co-rotation of pallet knife and grinding roller, pallet knife will lift the materials into the space between roller and ring to form a material layer. The materials will grinded due to centrifugal force of roller.
