The drum device is installed at an angle on the frame. The motor is connected with the drum device by the reducer and the coupling, which drives the drum device to rotate around its axis.
When the material enters the drum device, the material on the screen surface is turned over and rolled due to the inclination and rotation of the drum device, so that the qualified material (products under the screen) is discharged through the outlet at the bottom of the back end of the drum, and the unqualified material (products on the screen) is discharged through the outlet at the end of the drum. Because the material is turned and rolled in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking. The principle and structure of drum screening machine, drum screening machine and drum screening machine are almost the same, and there are differences in people's understanding and terminology of drum screening machine.
