[0002] In cement production, in order to improve the grinding efficiency and production capacity of cement mills, raw materials will be pre-crushed by roller presses before entering the ball mill for ball grinding, which not only reduces the pressure on the cement ball mill, but also improves the quality of ball grinding. At present, during the feeding process of the roller press, due to the certain height difference between the feed port and the roller press, the material will be affected by factors such as wind and eddy currents in the feed channel during feeding. When it falls on the roller press, there will be too much material on one side of the roller press and too little material on the other side.
