Drum filter also known as rotary drum filter is a type of filter that operates on gravitational principle. In some cases this equipment calls micro screen drum filter. It is used to separate fibers and solids from liquid phase.
Turbinedar Company uses self-cleaning baskets as drums to minimize maintenance costs. Slurry enters through feed pipe (5) to the basket filter (1) that includes a constant screw (2) and then distributed along the basket. Then liquid phase go through dam and discharge (7) and solid phase remains on the inner layer of basket and discharge with the screw. Drum rotates with the wheels on the main shaft (3) with the power of motor (4). To preventing the basket’s slots closure, it is possible to brush (8) the basket and wash it by water jets (9). The drum has been sealed with a casing (10) and used a pipe (11) to discharge volatile matters.
