The trommel screen is a widely used sorting machine that sorts garbage by controlling the particle size, and has high-precision sorting capabilities. Its composition usually includes motor, reducer, roller device, frame, sealing cover and inlet and outlet. Structurally, the cylinder of the trommel screen is generally divided into several sections, and the screen apertures of each section are arranged from small to large. In terms of working principle, when the material enters the drum device, the material on the screen surface is flipped and rolled due to the tilt and rotation of the drum device. In this process, qualified materials (products under the screen) will be discharged through the discharge port at the bottom of the rear end of the drum, while unqualified materials (products above the screen) will be discharged through the discharge port at the tail of the drum. In addition, the turning and rolling of materials in the drum help materials stuck in the screen holes to be ejected, thereby preventing the screen holes from being blocked. The characteristics of the trommel screen include low noise, easy maintenance, and can be closed. The screening cylinder can be closed, making it easy to seal and collect dust. At the same time, the reliability of the whole machine is high and the one-time investment is small.
