Rotex Screener

The classic Rotex machine is a proven rugged, long-lasting and versatile screening machine that has been used in countless applications throughout the world for decades. Featuring Rotex’s Gyratory Reciprocating Motion, the Rotex consistently delivers on-spec product with less rejection of good materials, resulting in increased profits.

Rotex screener models range from one to five screen surfaces (with sizes ranging from 0.8- 10.2 m2) for separations with openings from 12mm to 325mm mesh allowing for a complete bespoke screening solution.

  • Range of sizes from 9 sq ft to 110 sq ft (0.5m2 to 10m 2 ) of screen surface
  • Replaceable inner and outer seals to control dusting
  • Rotex reputation for quality, durability and ease of maintenance
  • Cost-effective construction and material options

Gyratory Reciprocating Motion

Gyratory Reciprocating Motion

The Gyratory Reciprocating Motion gradually diminishes along the length of the machine to an elliptical path and finally to a nearly straight line motion at the discharge end.

1. Circular motion at feed end

Spreads the material across the full width of the screen surface
Stratifies the material
Aggressively conveys material forward

2. Changing to elliptical motion at centre

Long stroke elliptical action
Enhances product stratification
Conveys material at high capacity

3. Straight-line motion at discharge end

Removes near-size particles
Improves screening efficiency
No vertical component ensures material is in constant contact with the screen surface

Floor Mounting

Because the Rotex counterbalanced drive has low transmitted forces, the Rotex can be floor mounted in properly designed structures, a design feature unique to this type of equipment. The Rotex can be mounted directly on the floor or on an elevated structural steel framework, which allows for drums and other equipment to be located under the machine. Rotex application engineers are available to recommend a stand for any specific application.

Cable Suspension

Rotex Screeners can be cable-suspended from the four corners of the machine, thereby isolating out-of-balance screening forces from the surrounding structure. Accurate counterbalancing of the Rotex Screener makes this type of installation option possible. If the existing overhead structure is not suitable or structurally unable to support the cable-suspended unit, the Rotex Screener can be suspended from a floor-mounted cable support stand. As with conventional cable suspension, this option effectively isolates the horizontal out-of-balance screening forces, which minimizes costs for new structures and permits the use of older structures that might not otherwise support cable-suspended equipment.

Positive Screen Cleaning

The bouncing action of the balls keeps screen openings clear, maintaining efficiency and capacity.

Automatic Tensioning

Unique screen attachment method eliminates need for tools and adjustment.

Dynamic Absorber Drives

ROTEX drives are designed for long term, trouble-free service with minimal maintenance required.

Inlet/Outlet Connections

The sliding inlet virtually eliminates the regular replacement of your flexible connecting sleeves, and will not crack or split because the sleeve is stationary.

Compensating Clamps

Patented spring actuated clamps take the guesswork out of cover clamping.

The video below shows the screener in action and also describes in detail the real benefits of this machine. The unique design reduces operating costs and increases throughput but this movie shows other unique advantages such as the benefits of gyratory reciprocating motion, low angle slope and screen selection.
