Working principle: The roller device is installed on the frame obliquely. The motor is connected with the roller device via a reducer through a coupling, Drum Screen 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, Drum Screen the material on the screen surface is turned and rolled, so that the qualified material (product under the screen) is discharged through the discharge port at the bottom of the rear end of the drum, Drum Screen and the unqualified material (the screen The upper product) is discharged through the discharge port at the end of the drum.
Due to the turnover and rolling of the material in the drum, Drum Screen the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked. The principle structure of drum screen sand machine, drum screen machine and drum screen is almost the same, but there are differences in people's understanding and name of it.
Scope of application: used in the quarry for the classification of large and small stones, Drum Screen as well as the separation of soil and stone powder; the separation of sand and stone in the sand and rock yard; Drum Screen the separation of lump coal and pulverized coal and coal washing (a component of coal washing machinery) in the coal industry; Industry, Drum Screen beneficiation industry is used to classify large and small lumps and separate powdery substances.
