Attapulgite Powder Vertical Mill

For the attapulgite powder vertical mill types, it has different kinds for different application. From the vertical mill on market, it has the following types of vertical mill roller: small and medium size mill roller, large scale roller, surface overlaying, thermometal alloy roller and metal matrix ceramic composites roller. These five kinds of roller will be made with different raw wear-resistant materials.

Thermometal alloy roller

On the ductile cast iron (HB320), this roller will be with high chromium cast iron block with enchasing dovetail groove in mechanical way. It has the following advantages: with the same material of high chromium cast iron, the mosaic block is higher than the overall casting roller hardness and it has good wear-resistant characteristics; the ductile cast iron has good opposite’s effects for the various stress diffusion in the grinding process. Even with the metal foreign bodies make mosaic block crack, it is hard to expand to the internal. The vertical mill will work more reliably. Between the mosaic block, there is ductile cast iron wear and it will form small grooves and increase the bite force of material. It can improve the grinding efficiency.

Metal matrix ceramic composites roller

It refers to put the ceramic particles evenly distributed in the honeycomb structure of high chromium cast iron. It has the following advantages: the ceramic hardness is higher than other kinds of hard materials and high chromium iron. It has good wear-resistance feature. The mill roller has longer service lifetime than the chromium and it will be improved with 3-5 times.
