The FZH series square cone mixer loads the materials into the square cone closed mixing barrel. The symmetrical axis of the hopper forms an angle with the axis of the rotary shaft. The materials of different components undergo three-dimensional spatial movement in the closed material door, resulting in strong turnover and diffusion. , To achieve the best mixing effect. The whole machine is novel in design, compact in structure, beautiful in appearance, and the mixing uniformity reaches 99% volumetric filling coefficient reaches 0.8. Low slewing height, stable operation, reliable performance, and easy operation; the square cone is a material truck, which can achieve the closed transportation of materials, avoid pollution, and meet GMP requirements; the inner and outer walls of the barrel are polished surface, no dead angle, easy to discharge, easy Clean.
