Rotary Drum Screen

Rotary Drum Screen is a kind of machinery widely used in the separation technology. It is used to control the garbage separation through the particle size, and the separation accuracy is high. The cylinder body of the drum screen is generally divided into several sections, depending on the specific situation, the sieve is arranged from small to large, and the sieve aperture on each section is the same. 

Rotary Drum screen is mainly composed of motor, reducer, drum device, frame, seal cover, inlet and outlet.

The working principle 

The roller device is installed on the frame at an Angle. The motor is connected with the drum device through the reducer through the coupling, and the drum device is driven to rotate around its axis. When the material into the drum device, due to the tilt and rotation of the drum device, so that the material on the screen surface flip and roll, so that qualified material (screen products) through the bottom of the end of the drum discharge, unqualified material (screen products) through the end of the drum discharge port. Due to the material in the roller flip, roll, so that the material stuck in the sieve hole can be ejected, prevent the sieve hole blockage. The principle and structure of roller sand screen machine, roller screen machine and roller screen are almost the same, which is the difference in people’s understanding and name. 

Characteristics

1, the sieve is not easy to plug. 

2, stable operation, low noise. 

3, simple structure, easy maintenance. 

4, screening cylinder can be closed, easy to airtight dust collection. 

5, the machine high reliability, less one-time investment. 

6, the use of special screen, high screening efficiency, long service life. 

 

Scope of application 

1. It is used for grading large and small stones and separating soil and stone powder in the stone field. 

2, sand and stone field for sand and stone separation. 

3, the coal industry is used for the separation of block coal and coal powder and coal washing (a component of coal washing machinery). 

4, chemical industry, mineral processing industry for the size of the block classification and separation of powder material.
