DSM SCREENS

Champion Screens offer a full line of gravity-fed DSM Screens available in the following types: 45°, 60°, 120°, 270°, 300°, and rap fine.

They are often used in the following industries: mineral processing, chemical, food and pulp & paper.

Each of these screen sizes has been tailored for a variety of process applications. For example, the 45° DSM screen is best suited for thickening and screening, whereas the 120° type DSM Screen is capable of thickening pulp, recovering fiber, or separating fiber as small as 100 microns in length from a water suspension. It is very compact and requires minimal maintenance.

The DSM's unique screen plate is made of vee shaped /wedge wire bars forming a bowed surface with horizontal slots between the bars. Normal slot width is 100 or 150 microns.

The flow to be screened is fed through a low pressure nozzle which distributes the flow tangentially over the full screen width by means of an adjustable slice that optimizes feed velocity. As the suspension flows along the screen plate, thin layers of water are ”sliced off” by the screen bars and pass through the slots together with fine particles.
