The rotary drum screen, or rotary sifter, is part of the equipment usually found in municipal and industrial water treatment processes.

Rotary Drum Screen or Rotary Sifter Features:

• body with flow channel and intake, outflow, overflow, and cleaning valves
• motor-driven slotted drum
• catcher
• cover

Rotary Drum Screen or Rotary Sifter Technical Details:

The Rotary Drum Screen or Rotary Sifter family of products ensures efficiency of from 30 to 2000 m3/h, depending on the size of the drum (diameter of 1200 mm or 3000 mm, length of 2500 mm to 9000 mm) and the size of the slots.

The side walls of the drum sieve can be made from:

• perforated sheet metal with a slot width of from 3 mm to 12mm (a sieve of this type may be used for preliminary cleaning of industrial sewage,for example to separate larger plant particles from rinse of cleaning water),
• trapezoid wire rolled into a cylinder of from 0.25 mm to 3.0 mm (this type of sieve can be used for the careful cleaning of products, for example to remove plant matter from juices, and in sugar refineries to catch the pulp of the diffusion juice and pressing water).

The rotation of the drum is powered by a reduction screw with an inverter controlled motor. Thanks to this, there is constant regulation and choice of optimal settings for a given solution. The inverter also makes automatic increase of revolutions possible when a greater flow of waste material is noted.

Thanks to its open side walls, it is possible to clean the insides of the drum without dismantling it. The specially designed shape of the body means that the interior can be isolated by means of a cover. This can be very useful when a liquid exudes an unpleasant smell or the product, for example a juice, could be contaminated from the outside.
