Eddy Current Aluminum Separators

The REMCON EDDY CURRENT SEPARATION CONVEYOR utilizes rare earth magnets, specially arranged inside the conveyor head pulley, to remove both aluminum and ferrous materials from commingled recyclables. Aluminum is repelled into a chute ahead of the pulley,  ferrous is attracted back to a chute behind the pulley, and other materials are dropped straight down into a third chute.

Remcon supplies two types of Eddy Current Separators (ECS) - Concentric Rotor & Eccentric Rotor Separators (the rotor is essentially the conveyor pulley at the discharge end of the ECS that contains the rotating ECS magnets);
Concentric Rotor Separators have rotors with  magnets that rotate around an inner shaft that is positioned concentrically (evenly spaced) around the center of the outer pulley shell. The concentric rotor separator is simpler in design and less costly than eccentric rotors. They are an effective option for medium and smaller volume operations that separate primarily aluminum cans. We buy rotors for concentric versions and build the remainder of the machine, often with custom design modifications to better fit certain applications. These include custom support stands, infeed conveyors, outfeed conveyors and blowers, transitions and chutes, etc. ​

DIMENSIONS
Overall Width – 66” (with 30” rotor)
Standard Overall Length (other lengths available as needed) – 137”

BEARINGS
Dodge SXR pillow block with eccentric locking collar for better grip on shaft.

BED
3/8” thick flat bar slat construction, slider style with sealed belt edges for reduced belt wear and safety. Slat bed construction decreases friction and drag from moisture on the belt and prevents abrasive debris from accumulating underneath the belt.  

BELT
Polyurethane – provides the greatest strength with the least thickness, to avoid dampening the effect of the eddy current. The belt connection and sidewalls are permanently hot bonded at the factory.  The design of the conveyor structure allows endless belts to be installed and removed with minimal disassembly

BELT CLEATS
2” tall, 18” spacing, high Radio Frequency welded to top surface of belt to move product efficiently thereby reducing belt wear.

BELT EDGE SEALS
A 2” tall PVC side wall is hot air welded to the surface of the belt and steel skirting hangs over belt sidewall to prevent glass and metal debris from working under the belt edge and causing premature belt wear.

BELT SPEED
200 feet per minute fixed speed.

EDDY CURRENT ROTOR (CONVEYOR HEAD PULLEY)

• Rotor Construction – Contains high grade rare-earth permanent magnets that are balanced for low vibration and long life. 
• Rotor Shell – A replaceable fiberglass wear drum covers and protects the inner rotor and supports the conveyor belt.
• Rotor Diameter – Available in 12", 14", or 16", depending on what strength is needed based on the size and density of aluminum objects being removed
• Rotor Width – Extra wide rotor design positions bearings out of the magnetic field and keeps the product away from the edges of the belt to prolong belt and rotor life.

FRAME
Formed 3/8” plate steel dampens vibrations, and has guarded access holes in the sides of the conveyor.

GEAR REDUCER OPTIONS (for conveyor belt drive)

• Dodge Torque Arm II, parallel gear, shaft mounted gear reducer, sized to meet American Gear Manufacturers Association class 2 rating.
• Nord Flexbloc™ worm-gear style shaft-mounted gearmotor, sized to meet American Gear Manufacturers' Association class 2 rating.

HOOD
Splitter included to separate metallic stream from non-metallic stream.

LEGS
Custom built to support each Eddy Current Separator as needed for each location

MOTOR (for conveyor belt drive)
TECO-Westinghouse 3/4 HP, severe duty, TEFC, 1.15 service factor, class F insulation for long motor life.

MOTOR (for rotor drive)
TECO-Westinghouse 10 H.P., severe duty, TEFC, 1.15 service factor, class F insulation for long motor life 

PULLEY, TAIL
14” diameter, driven by a shaft-mount gear reducer and conveyor motor, crowned for belt tracking.

BELT TAKE-UP
REMCON conveyors are equipped with extra long belt take up devices which allow more than enough adjustment for the maximum amount of guaranteed belt stretch. ​

EMERGENCY STOP SYSTEM
Cable-pull switch with cable and rigging as required by OSHA.

GUARDS
All drive components guarded with hinged covers.
