Trommel rotary sand sieving machine is a kind of machinery widely used in separation technology. It controls the separation of materials by controlling the particle size, and has high separation accuracy. It is mainly composed of motor, reducer, drum device, frame, sealing cover and inlet and outlet.
The working principle of the drum rotary screen is that the motor drives the drum installed on the frame inclined to rotate around its axis through the reducer and coupling;
When the materials enter the drum, due to the tilt and rotation of the drum, the materials on the screen surface are constantly overturned and rolled. At the same time, the materials are separated and screened from the top to the bottom. Due to the different screen specifications, the materials are gradually separated and screened, and the materials with qualified particle size (under screen) fall into their respective hopper after screening, and the unqualified materials (screening materials) pass through the discharge port at the tail of the drum Discharge: due to the turnover and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking.
