Detailed description of the invention
As Fig. 1, shown in 2, blast-furnace cinder System of Ultra Thin Power Rubbing of the present invention, comprises as lower component: connected superfine pulverizer (1), be located at the powder concentrator (2) in connected superfine pulverizer (1), the screw feeder (3) being connected with connected superfine pulverizer (1) one side and the oil hydraulic system (4) being connected with connected superfine pulverizer (1) opposite side, described connected superfine pulverizer (1) comprises motor (1-1), the reductor (1-2) being connected with motor (1-1), be located at the mill (1-3) in connected superfine pulverizer (1), the grinding roller (1-4) being connected with mill (1-3), the air inlet (1-5) and the foreign material outlet (1-6) that are located at connected superfine pulverizer (1) bottom, described powder concentrator (2) is dynamic powder concentrator, described powder concentrator (2) comprises power transmission shaft (2-1), the impeller (2-2) being connected with power transmission shaft (2-1), the guide vane (2-3) being connected with impeller (2-2), be located at the ash bucket (2-4) of impeller (2-2) and guide vane (2-3) below, be located at the discharge pipe (2-5) of impeller (2-2) and guide vane (2-3) top, be located at air outlet and the fine powder outlet (2-7) of discharge pipe (2-5) opening part, be located at the meal outlet (2-6) of ash bucket (2-4) below.
The grinding system course of work of the present invention is as follows: equably material is fed to the central authorities of the mill horizontally rotating with conveying worm, material is subject to the effect of centrifugal force, from the outside Zhou Yidong of central authorities. On the raceway of mill periphery, several (2～4) grinding roller is installed. Material, between grinding roller and mill raceway, is squeezed and grinds stripping effect and pulverize, and then continues to move toward periphery. Mill is around air port, and air (can be hot gas or kiln waste gas) enters grinding machine inner chamber through spout, and convolution is risen, and the powder concentrator that takes top through the material of pulverizing to is selected to powder. Thick particle falls, and mixes with the material of new feeding, gets back to once again mill, accepts pulverizing. The fine grained of selecting---fine powder, through the middle part of rotor of powder separator, deflects from grinding machine. The field trashes such as sheet metal drop in ascending air, discharge through foreign material outlet.
