LSSHJ Series Dual shaft continuous mixer has a new rotor structure without mixed blind angle, and has fine mixing uniformity. The space between rotor and machine housing can be adjusted. One end at the bottom is for continuously discharging with few material residual. The other end of the machine is for gear meshing and transmission, preventing materials leakage at the ends of both shafts; the decrease of the transmission power greatly reduces the energy consumption, the length of the machine casing is longer and the degree of homogeneity is higher, moreover, the mixing is continuous, accurate and reliable. The machine is equipped with liquid adding pipeline and feeding and discharging are combined organically, thus reducing installation height of the equipment, making the equipment have reasonable overall structure and beautiful appearance, and easy to operate and maintain.
