Efficient super-fine disintegrator

The utility model relates to a device of milling elements and pulverizing elements which jointly acts by a roller and a ring. The device comprises a driving part, a main motor for the driving part, a rotor part, a barrel and an inlet of material. A distribution plate, a roller frame and a material inputting plate are installed by a main shaft in series in the rotor part. A rolling surface is formed by a roller on the roller frame and a milling ring. A ventilated jacket and a wind chamber are also arranged in the barrel, and an analyzer is arranged on the barrel. The powder which is reached to the requirement of the degree of the fineness is exhausted form the powder winding port and is collected by the mode of up sucking. The device adopts the multiple-layered rolling and the powder conveying by airflow to enhance the productive rate of the fine fraction. The device is applicable to the mining industry, the chemical industry, the building material, the foodstuff and the medicinal industry.
