Among them, the first screw pulp 200 and the second screw screw 201 are asymmetrically arranged in the agitator 20, and the third screw screw 202 is the central screw screw. Specifically, the blending process of the equipment is as follows: the first speed reducer 204 drives the first screw slurry 200, the second screw slurry 201, and the third screw slurry 202 to work, and the first screw slurry 200 and the second screw slurry 201 work. , And the third screw slurry 202 drives the material to turn up and down. The two asymmetric first screw slurry 200 and the second screw slurry 201 rotate rapidly, and the material rises upward to form two asymmetric spiral material flows from bottom to top along the cylinder arm. The central screw slurry pushes the material downwards, so that the material generates a circulating flow to achieve the purpose of blending. The material is lifted from the bottom to the top, and at the same time, part of the material is thrown to the space at a large spiral speed, and flows downward along the circumference by the material's own weight, thereby generating strong convective shearing, blending and diffusion in a short time, and continuous circulation. To achieve the purpose of uniform blending. By arranging the first screw pulp 200, the second screw pulp 201, and the third screw pulp 202, the first screw pulp 200 and the second screw pulp 201 are arranged asymmetrically, which has the advantages of uniform blending, automatic blending, and high blending efficiency.
