[0002] The ring die granulator is a kind of mechanical equipment for extruding solid materials, and its working principle is that the raw materials are compressed into granular materials of a required size through the pressure in the ring die (ring die) and the rotation of the external roller (press roller). During the working process, the ring die rotates clockwise, and the raw materials enter the granulation chamber after being conditioned. The press roller also rotates clockwise under the driving of friction. The rotation of the die roller moves the raw materials at a high speed, and the extrusion force gradually increases. When the extrusion force increases to a certain extent, the raw materials will overcome the friction and enter the ring die hole. With the continuous rotation of the roller die, the raw materials continuously enter the ring die hole, and are extruded out of the ring die hole after being formed and cut, thereby forming the required product.
