The roller device is installed on the frame obliquely. The motor is connected with the roller device through a coupling through a reducer, and drives the roller device to rotate around its axis. When the material enters the drum device, due to the inclination and rotation of the drum device, the material on the screen surface is turned and rolled, so that the qualified materials (products under the screen) are discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified materials (the screen The upper product) is discharged through the discharge port at the end of the drum. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked. The principle and structure of drum screen sand machine, drum screen machine and drum screen are almost the same, but there are differences in people's understanding and name of it.
