Drum Rumble

Drum separator (screen) for solid waste is an equipment as part of a waste sorting complex designed to separate small organic fractions of solid household (MSW) and solid municipal waste (MSW) by sifting fractions of raw materials through the walls of a metal drum mounted at an angle, rotating due to the support rollers on which it is installed.

The principle of operation of drum separators (screens) for solid waste

The loading of solid waste and MSW is carried out in the hopper of the screen drum. The waste trapped inside the drum performs a complex rotational and translational movement, passing through the holes of the drum, is divided into fractions. The fine fraction, waking up through the cells of the drum, enters the discharge conveyor and is discharged into a container for further export to the landfill. A large part goes to the next stage of the production cycle. An auger is placed inside the screen, the blades of which are arranged in a spiral

they are fixed on the inner surface of the cylinder, this ensures better sorting due to the uniform distribution of waste on the inner surface of the cylinder and better screening of small objects and fractions consisting of biological waste, street dust, etc. In addition, the design of the screen provides for preventing flat objects, such as pieces of plastic film and cardboard, from rolling down the inner wall, this it is observed with an inclined screen arrangement. The protrusions on the auger blades ensure constant loosening of waste, which also improves the quality of sorting.

Fields of application of drum type screens

As a rule, this type of drum screen is used in the recycling of construction, mining and woodworking industries for sorting by fractions of various materials.

Recently, drum separators have been actively used by enterprises engaged in the recycling of garbage and various waste products. For example, one of the latest innovations in public utilities and waste management has become a drum separator with a magnetic separation function, which allows you to capture and separate metal-containing components from other objects.
