The spiral belt cooler is based on the horizontal spiral belt mixer by adding jacket and thermal insulation to realize the purpose of cooling materials. It is mainly composed of transmission mechanism, vertical cylinder, mixing system, etc. Under the action of inner and outer spiral belts, the materials move along the axial convection, so as to achieve uniform mixing in a short time. Adding a jacket on the screw belt mixer can make a screw belt mixer that can complete the reaction, mixing and other processes in one step, which can greatly improve the product quality, output and efficiency.
