Working principle and performance

When the drum screening machine is working, the motor is connected with the drum device through the reducer through a coupling, and the drum device is driven to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled, so that the qualified materials are discharged through the screen on the outer circle of the drum, and the unqualified materials are discharged through 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, which can prevent the screen hole from being blocked.

In the process of use, the cylindrical rotary screen runs slowly and evenly, with little impact and vibration, stable operation, simple installation, and sometimes even no special foundation is required. It can be placed directly on the flat ground or floor and under the silo. The machine is easy to seal and collect dust, with small maintenance, simple maintenance and long service life. It is a frequently used equipment in the classification of refractories, coal, river sand, and sand and gravel.
