[0029] This application provides a high-efficiency material distribution device for a cement roller press. The frame includes four baffles: a first baffle 131, a second baffle 132, a third baffle 133, and a fourth baffle 134.

[0037] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly explained below in conjunction with specific application scenarios: Specifically, the fabric feeding device starts working, and the two motors drive the two spiral cutters to start rotating. The motors are variable frequency speed control motors, which can adjust the speed according to the distance between the roller gaps. When the roller gaps are large, the speed of the motors is reduced; when the roller gaps are small, the speed of the motors is increased to keep the material entering the roller gaps stably. When the cement raw materials enter the feeding device through the opening of the mixing unit 1, they are first stirred by the two spiral blades in the mixing unit 1, which breaks up some of the lumpy wet materials. Due to the open design of the frame, the cement raw materials can be dispersed and fed out, and the two spiral blades can rotate around the circumference, which can disperse and mix all the cement raw materials evenly. The evenly mixed material enters the feeding unit 2 and is guided by the two limiting plates and the two feeding plates to accurately enter the roller gap. Since each feeding plate is connected to a hydraulic cylinder, the feeding plate is controlled by the hydraulic cylinder to adjust the first angle α, so that the feeding plate acts as a guide plate to accurately guide the material into the roller gap. Furthermore, the opening distance between the two feeding plates is the second distance L2. The second distance L2 is determined by the two hydraulic cylinders adjusting the first angle α formed between the two feeding plates and the mixing unit 1. Since the roller gap is the first distance L1, when the second distance L2 is less than the first distance L1, the material discharged from the feeding device can accurately enter the roller gap.
