Trommel Screen

The trommel screen is a kind of beneficiation equipment which is classified according to the particle size of the material. It is generally used for the classification and screening of medium and fine grain materials. It has the characteristics of stable operation, low energy consumption, easy maintenance, simple and flexible process layout, and can be widely used. It is applied to the classification of products in mining, building materials, transportation, energy, chemical and other industries, especially for the grading and screening of ceramsite.

The roller unit is mounted obliquely on the frame. The motor is coupled to the drum unit via a coupling through a reducer to drive the drum unit to rotate about its axis. After the material enters the roller device, due to the tilting and rotation of the roller device, the material on the sieve surface is turned over and rolled, so that the qualified material (the product under the sieve) is discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified material (screen) The upper product is discharged through the discharge opening at the end of the drum. Due to the turning 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 clogged. The principle structure of the drum sander, the drum screener and the drum screen is almost the same, and there is a difference in people's understanding and calling.
