Continuous Slot

Johnson Screens^® continuous slot is the highest open area, fine aperture modular screen panel in the world today, combining the advantages of the long wear life characteristics of polyurethane with the high open area pattern of profile wire.

Open area, or ratio of apertures to total panel surface area, is of crucial importance to screen users at a time when plants are upgrading capacity to increase profitability and maximizing screen performance.

Open area for the continuous slot pattern is about 40 to 50 percent greater than standard polyurethane modular panels of the same aperture, which means greater throughput through the same screen or alternatively much better quality of the screen products for the same feed.

In fine apertures, deviation from tolerance can lead to reduced recovery, large losses of valuable screen product and reduce plant profit. Continuous slot panels have +/- 10 μm standard deviation over the specified aperture size.

Field tested over a period of two years in a number of coal screens, continuous slot panels can be used in any fine aperture (less than 0.06 in. / 1.5 mm) screening application. Continuous slot is compatible with horizontal or banana-type screen decks and is ideally suited for dewatering, de-sliming or fine classification and drain/rinse heavy media recovery applications.

The continuous slot aperture design is compatible with the Pipo^® Two, Pipo Three, J-Loc^® and Koko^® product ranges.
