1results about How to "Reduce crushing process" patented technology

This application discloses a screw conveyor and a dryer discharge system with grading and crushing functions. The screw conveyor includes a cylinder, a shaft, screw blades a and b, a motor, and a separation pipe and a feeding pipe perpendicular to the cylinder. A feed inlet is located at the left end of the cylinder. The feeding pipe and separation pipe are located at the top and bottom of the cylinder, respectively, and their air passages are connected. An air chamber is located on the outside of the separation pipe. A smooth shaft is located in the middle of the shaft, corresponding to the junction of the separation pipe and the feeding pipe. Screw blades a are located at the left end and b at the right end, with the two screw blades rotating in opposite directions. Material enters the cylinder through the feed inlet and falls into the separation pipe under the action of screw blades a. Smaller particles are carried by the airflow and flow out through the upper air outlet a via the feeding pipe for gas-solid separation. Larger particles and lumps are directly crushed. The screw conveyor and discharge system of this application can grade, convey, and crush dried products, reducing the transportation and crushing processes of lumps, saving manpower, and being environmentally friendly.
