Trommel Screen - Pulp & Paper Machine

Parason produces the most durable and efficient trommel screens in the pulp & paper industry. Using a revolving screened cylinder to accomplish the separation of material by size, our trommel screens are ideal for Construction and Demolition waste, Municipal Solid Waste, Green Waste and Waste to Energy front-end separation systems.

Our trommel screens are positioned at the beginning of the equipment line, replacing the need for multiple pieces of equipment. All our trommel screens are engineered with an energy efficient design that utilizes gravity and centrifugal force to separate different material sizes from the waste stream.

Features -

• Easy Installation
• Perforated drum of SS-304, drive arrangement, inside helical screw, out let chute of SS-304 and Supporting Structure of M.S.
• Drum is driven through Geared Motor, Pulleys and Belts
• C-I drive and driven pulleys properly machined
• Shower pipe with nozzles of SS-304

Application -

• For separating fibers and large coarse contaminants from the recycled fiber pulp after the Pulper
• Special heavy duty perforated drum allowing the recovery of fibers and rejecting the coarse contaminants, accepts returned to the Pulper
• Works as a Secondary Coarse Screen and installed in Pulper reject/accept line depending on type of Pulper & contaminants

Working Principles -

The Trommel is an rotating perforated drum. Contaminants and fibers fed into the Trommel screen from one end.To increase fiber recovery, the Trommel is slowly rotated to agitate the stock, water is added through shower provided to aid the fiber/ contaminants separation, large contaminants are rejected from the system as the helical screws welded inside the drum, force them out from order end of the Trommel.

The suitable hole size of the perforated drum is selected to optimize the separation properties and fiber recovery qualities. The accept from the Trommel containing fiber, water and small contaminants collected in the tray by gravity and feed back to the Pulper.
