Sintering granulation is an important part of the preparation of raw materials in metallurgical production. At present, the traditional granulating equipment is mainly cylinder granulating machine, which has poor mixing effect, the inner wall of the drum of the cylindrical granulator is easy to scale and affect the granulation. Therefore, a new type of mixing granulation equipment is proposed, which can improve the mixing degree of raw materials, improve the granulation efficiency and have the function of "self-purification". The design of the built-in mixing knife has a direct influence on granulation effect. Under the high-speed rotation of the mixing knife, the mixture generates complex and strong convection mixing motion along the axial direction and the radial direction until the particles collide with each other to realize the granulation process. The particle size distribution is uniform. The strength of the granules is effectively improved, and the granulation effect is ideal.
