ROTEX INDUSTRIAL SCREENERS
Meet the machine that launched an industry. Precise. Rugged. Versatile. Rotex®
Drive Head
Rotex drive heads come in three configurations.
- Single Weight Drive: Used on smaller machines; only requires major counterweight for balancing and can be cable-suspended or floor-mounted.
- Dynamic Absorber Drive: Uses a major counterweight combined with leafsprings and weight packs to achieve balancing; these machines must be cable-suspended.
- Gear Drive: Uses both major and minor counterweights to achieve balancing; these machines can be cable-suspended or floor-mounted.
Drag Link
The drag link is a physical connection that attaches the screen box assembly to the machine base; this connection converts the gyratory motion created by the drive head to reciprocating motion for precise, near-size separation.
Compensating Clamps/Screen Frame Removal
The top cover is the main point of access to the screen decks; by releasing the toolless compensating clamps and lifting the cover off, you can access the screen frames directly. Each deck must be removed for screen change-out. The screens are attached using Rotex tensioning clips, which automatically draw the correct tension on the screen clothing.
Inspection Ports
Inspection ports are located on the top cover of the machine. When the machine is stopped, you can easily remove the inspection cap and ensure the screener is operating correctly. This could include inspections for screen blinding, screen tears or material buildup.
Inlet Connection
Rotex customizes each machine configuration to match the exact application needs. Inlet connection options include:
- Traditional flexible connections
- Rubber, EPDM, silicone, nylon, polyurethane, Teflon™
- Sanitary BFM connections
- Specialized connections
- Nutating connections, sliding connections, inlet chute
Outlet Connections
Rotex customizes each machine configuration to match the exact application needs. Outlet connection options include:
- Traditional flexible connections
- Rubber, EPDM, silicone, nylon, polyurethane, Teflon™
- Sanitary BFM connections
- Specialized connections
- Nutating connections
Slide Bearings
Slide bearings are bearings where only sliding friction is generated. The shaft is generally supported by the sliding surface, with oil and air in between to facilitate sliding movement. Sliding bearings are lightweight and have a long operating life while introducing minimal vibrations or noise.
Discharge Chute
The APEX™ discharge chute offers easily accessible outlets and customizable outlet configurations. Outside of the outlets, you can also customize the discharge chute by adding hinges to improve accessibility for product cleanouts and inspections. Lastly, you can include up to two different aspirated fractions for added separation capabilities.
The Rotex® industrial screener with automatic tensioning delivers on-spec product with less rejection of good materials for increased profits. Rotex endures today as the industry standard thanks to countless applications in the toughest conditions around the world.
Features
How It Works
Rotex’s Gyratory Reciprocating Motion
The Gyratory Reciprocating Motion gradually transitions along the length of the screening machine, starting off as purely gyratory motion at the head, then moving to elliptical movement in the center and reverting back to reciprocating toward the end.
- Circular motion at feed end
- Spreads the material across the full width of the screen surface
- Stratifies the material
- Aggressively conveys material forward
- Changing to elliptical motion at center
- Long-stroke elliptical action
- Enhances product stratification
- Conveys material at high capacity
- Reciprocating motion at discharge end
- Removes near-size particles
- Improves screening efficiency
- No vertical component ensures material is in constant contact with the screen surface
Benefits
Eliminates Screen Blinding
Through the use of Rotex’s mesh cleaning balls and Gyratory Reciprocating Motion, material blinding is virtually nonexistent.
Consistent Screen Tension
The screen is automatically tensioned with each new installation through the use of our unique screen-attachment method.
Longevity and Durability
Rotex drives are designed for long-term, trouble-free service with minimal maintenance.
Increased Screening Performance
All Rotex machines deliver greater efficiencies, superior particle accuracies and higher yields.
Product Options
Rotex General Purpose
The Rotex general-purpose separator is a cost-effective solution that uses proven Rotex technology, but with wooden screen frames. This machine is recommended for applications where wood is permissable in the separation process and the separations are coarser than 30 mesh.
Rotex Dairy Screener
The Rotex Dairy Screener was custom-designed to meet the specific needs of the dairy industry. This exclusive machine generates higher yields and finer separations with no blinding. Best of all, it’s easy to clean during change-outs, reducing the chance of contamination.
Installation
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 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. Note that certain Rotex models can only be cable suspended.
