Original Press Release:

New Rotex® Plastic Pellet Screeners with Capacities up to 5,000 PPH Offer Unequalled Removal of Off-Size Material

CINCINNATI, OH (July 11, 2002) - Expanding the options for compounders seeking extremely accurate removal of off-size material, ROTEX has added two new models with capacities up to 3,000 PPH and 5,000 PPH to the competitively-priced, high efficiency line of ROTEX® Plastic Pellet Screeners

The new ROTEX Plastic Pellet Screeners utilize a unique horizontal, gyratory/reciprocating motion, and an exclusive patent-pending "Dual Velocity" drive with a positive displacement stroke to achieve unmatched removal of oversize and longs.

The long stroke, gyratory motion - four times as long as vibratory screeners - spreads pellets evenly across the full width of the unit. The motion then stratifies the material for exceptionally efficient fines removal and separation of the oversize from the on-spec pellets. Good pellets are not removed with the oversize.

The ROTEX motion contains no vertical component, so long pellets, "toothpicks" and "jackstraws" remain flat on the screen deck. They cannot upend or pass through the screen with the on-spec pellets, as they often do with vibratory screeners. For increased accuracy, a double pass option is available to screen pellets twice. Final product can be up to 99 percent free of longs 3/8" to 2" (0.9 to 5 cm).

The reliable, low-maintenance "Dual Velocity" drive operates at lower speeds, reducing noise and wear on components, and minimizes vibration with a counter-weight drive.

ROTEX Plastic Pellet Screeners are easily disassembled and reassembled for regular maintenance or for cleaning between batches, and are portable and simple to move off-line.

With compact footprints and lower silhouettes than most other screening machines, ROTEX Plastic Pellet Screeners have an installed height as low as 27" (69 cm). Mounting options include casters, kick-down legs or a stand.

When running longer batches without interruption for cleaning, unique variable frequency tappers can be added for additional control of screen blinding without the use of mesh cleaning balls. Optional stainless steel wire screens, perforated plates or a combination of the two can be installed to meet any separation requirement.

The 3,000 PPH and 5,000 PPH capacity models join the ROTEX Plastic Pellet Screener designed to handle capacities up to 1,500 PPH, which was introduced last year. ROTEX also offers a wide range of pellet screeners for higher capacity screening up to 30,000 PPH with the same gyratory/reciprocating motion, accurate separation, compact design and installation configurations, and easy cleaning.

ROTEX INC. engineers and manufactures a full line of screening equipment including ROTEX® Screeners and high capacity MEGATEX(TM) Screeners for particle size separation of grains, minerals, plastics and other dry solids; GRADEX(TM) Particle Size Analyzers; and LIQUATEX(TM) Liquid/Solid Separators.
