Introduction to drum screen:

Drum screen, also known as drum screening machine, is a widely used product in screening machines. It is a new generation of screening machine, usually using a combination screen. It is widely used for screening various solid materials with particle size less than 300mm, and the screening capacity is generally between 60 tons/hour and 1000 tons/hour. Drum screen can be used for cleaning, impurity removal, size grading, etc., and is widely used.

working principle:

The structure of the drum screen mainly consists of a motor, a reducer, a drum device, a frame, a sealing cover, and an inlet and outlet. The working principle of the drum screen is that the motor and the drum device are coupled together through a coupling to drive the drum device to rotate around its axis. After the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface flips and rolls. This is achieved by using the relative motion between the scattered material and the screen surface, allowing some particles to pass through the screen holes and divide materials such as sand, gravel, and crushed stone into different grades according to particle size, thus completing the screening function.
