Work, the material from the hopper to join, push and squeeze through the screw, the material temperature, viscosity increases, and then cut out from the template holes formed cylindrical particles. Screw extrusion granulator range of applications and key features: The function of two or more chemical raw materials without adding water and a binder extrusion granulation, the diameter of the cylindrical pellets form a variety of specialized equipment; Continuous, gap can work, unidirectional rotation (when facing the head of the screw should be rotated clockwise, can not reverse); The machine is simple structure, easy maintenance, strong adaptability. Suitable for pelletizing various powder materials.
