Rotary Drum Screen

Introduction: Drum screens, with their strong adaptability, low clogging rate, and energy efficiency, have become key equipment for solid material classification, particularly suitable for challenging environments such as mining, coal mining, and construction waste. The drum screen is designed to solve the problem of wet and sticky material screening blockage. The main body includes a screen drum, a drive system (motor + reducer), a frame and a sealing cover. The screen drum is composed of wear-resistant flat steel rings or special screens. The segmented design can achieve multi-level screening (such as fine → coarse 4-level screens).
Working principle: After the particles enter the drum device, they first fall into the buffer drum. Due to the inclination and rotation of the drum device, the materials on the buffer drum are scattered on the drum screen. After flipping and rolling, and moving to the discharge end due to gravity, the particles smaller than the screen hole (screen under) pass through the screen hole and fall into the collection hopper, and the particles larger than the screen hole (screen over) are discharged through the coarse material outlet at the end of the drum. Due to the flipping 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 blocked. The comb-type cleaning mechanism is used to clean the screen surface in real time to ensure continuous and efficient screening.
