About Me

The Rotary Screen is also called a cylindrical sieve. It is a kind of machinery widely used in the sorting technology. It is used for the classification and screening of medium and fine crushed materials. In the stone yard, it can be used for grading of large and small stones, and separating the soil and stone powder outside the stone; in the sand field, it can be used for separation and screening of sand and stone; in the chemical industry and coal industry, it can be used in bulk materials and screening of powdered materials.

Equipment composition
The Rotary Screen mainly consists of motor, reducer, roller device, frame, sealing cover and inlet and outlet. The barrel body is generally divided into three sections, each of which has a length of 80cm, a diameter of 60cm, and a diameter of 13mm, 50mm, and 200mm, respectively. In the first section, the screening components are mainly fine particles of coal ash, soil, and fine metal particles. The second section contains small bricks, stones, some plastics, paper, etc. The third part of the screening ingredients is paper, plastic, bamboo wood, rubber, and so on. The screen holes are arranged from small to large, with the same size on each section.
In order to improve the screening efficiency, the speed of the material moving in the drum screen should not be too fast, otherwise, the screening will be insufficient and incomplete. Therefore, the drum screen generally has a strict installation angle, which is usually 5掳. In actual situations, adjustments can be made as needed.
The roller segment is connected to the roller screen turntable by nuts and screws, so the installation and disassembly of the roller segment are convenient. Since the drum section is connected to the turntable, when the turntable is rotated by the driving means, the drum section is also rotated together.

Working principle
The roller device is mounted on the rack obliquely. The motor is connected with the drum device through a coupling, and the driving drum device rotates around its axis. When the material enters the cylinder device, due to the tilt and rotation of the cylinder device, the material on the screen turns over and rolls and the qualified material (the product under the screen) is discharged through the discharge port at the bottom of the back end of the cylinder, while the unqualified material (the product on the screen) is discharged through the discharge port at the end of the cylinder. Due to the material in the roller turnover and rolling, the material in the mesh can be ejected to prevent the mesh plug.
