Eriez Manufacturing Co. / Eriez Magnetic Separators, Vibratory Feeders and Metal Detectors

Selection and quotation of Eriez equipment: SE-7000, CP and TP suspended magnets, magnetic drums and grates, RevX-E eddy current separators, B-HC and Hi-Vi feeders, MetAlarm and X8 metal detectors, flotation columns and SlamJet spargers.

SE-7000 Suspended Electromagnets

SE-7000 magnets hang over a belt conveyor to pull large tramp metal ahead of crushers and mills. Aluminium coils run in oil with an external expansion tank, and discharge is manual or self-cleaning. Compact force-cooled, dry and SE-2400 chute units are also built.

Magnet sizes: 23
Standard models: 69
Manual or self-cleaning
SE-2400 chute unit: 55° legs

CP and TP Suspended Permanent Magnets

CP and TP magnets use ceramic magnet material, need no power and keep a continuous field across the belt; the self-cleaning belt has an electric or hydraulic drive. CP suits about 250 mm suspension and dual pole TP about 300 mm on belts under 1 m.

CP suspension: about 250 mm
TP suspension: about 300 mm
Belt width: under 1 m
Electric or hydraulic drive

CC, RE and A Magnetic Drums and Magnetic Pulleys

Permanent magnet drums remove large and small iron and discharge it outside the field. Type CC has a criss-cross circuit, Type RE uses rare earth magnets for fine particles, and Type A agitates the burden. A magnetic pulley serves as the conveyor head pulley; Model AA works above 121°C.

Drum diameter: 305-915 mm
Drum width: 305-1525 mm
Volume: up to 725 m³/h
AA pulley: above 121°C

Grate Magnets, Easy-to-Clean and Rota-Grate

Grates sit in hoppers and chutes: the product passes between magnetic tubes and iron stays on them. Standard grates use ceramic or Alnico magnets, and Xtreme RE rare earth grates hold fine iron. Easy-to-Clean units are cleaned by pulling the tubes; Rota-Grate turns its tubes in sticky products.

Tubes: 25 mm on 51 mm centers
Rota-Grate: 24 sizes
Gear motor drive: 16 RPM
Sanitary stainless design

RevX-E and UHF Eddy Current Separators

RevX-E separates nonferrous metals: an eccentric rare earth rotor spins inside a non-conductive shell faster than the shell and throws aluminium and copper off the belt end. The cantilevered frame allows a 10 minute belt change. The UHF unit with a 32 pole rotor recovers metal from 2-3 mm.

Widths: 1.0, 1.2 and 1.5 m
LT2 rotor: 8 poles
ST22 rotor: 22 poles
Belt change: 10 minutes

Electromagnetic and Mechanical Vibratory Feeders

B-HC feeders with an electromagnetic drive and rare earth armature meter ore and stone to conveyors, screens and crushers with no sliding parts. Hi-Vi Models A, C, HS and HD handle small doses, while Brute Force with twin rotary motors and HVF with an eccentric shaft handle large flows.

B-HC feeders: 300-982 t/h
Model A: up to 2 tons/h
HD tray stroke: 4.8 mm
HVF speed: up to 18 m/min

MetAlarm and PrecisionGuard X8 Metal Detectors

MetAlarm units install without cutting the belt: TR and BR for troughed belts, PL for flat belts and mobile crushers, VC for vibratory conveyors; a trip stops the feed. Touchscreen X8 and X8-SF units find ferrous, nonferrous and stainless steel metal in food and liquid products.

TR belt: 500-2000 mm
BR burden: over 356 mm
HH-10 handheld: from 1 mm
X8 liquid line: 38-102 mm

Flotation Columns, HydroFloat and SlamJet Spargers

Eriez columns give multi-stage flotation in a single cell with full-surface froth wash water and no rotating wear parts. SlamJet spargers make fine bubbles, are removed without draining the column and shut on supply gas failure. HydroFloat floats coarse particles in an aerated fluidized bed.

Columns supplied: over 1,280
Countries: 45+
HydroFloat feed: up to 4 mm
Feed solids: 50-60%

Choosing a Tramp Metal Magnet for a Belt or Chute

An SE-7000 suspended electromagnet is sized by belt width, speed, burden depth and material type: it removes large tramp metal ahead of crushers and mills, with manual cleaning for low tramp loads and self-cleaning units for steady flows.

CP and TP permanent magnets need no power and suit belts under 1 m and mobile crushers. Drums and magnetic pulleys discharge iron automatically, while grates and Rota-Grate protect hoppers and chutes.

Nonferrous Metal Recovery Line

The RevX-E eddy current separator comes in 1.0, 1.2 and 1.5 m widths, and the rotor is chosen by particle size: the 8 pole LT2 for coarse material over 1 inch and the 22 pole ST22 for 1/4 to 1 inch fractions.

The UHF separator with a 32 pole rotor recovers nonferrous metal and bare copper wire from 2-3 mm; each 1.0 m unit ships with a Brute Force feeder for even distribution across the belt.

Feeders and Metal Detectors on the Line

B-HC electromagnetic feeders deliver 300 to 982 t/h and meter material to conveyors, screens and crushers; light Hi-Vi Models A, C, HS and HD feed from a few pounds per minute up to 2 tons per hour, and HVF feeders with rubber springs reach 18 m/min.

MetAlarm conveyor detectors are chosen by belt type: TR for troughed belts 500 to 2000 mm wide, BR for burdens over 356 mm, PL for flat belts and mobile crushers.

Flotation Columns and Spargers

Eriez has supplied more than 1,280 flotation columns to over 45 countries, and one column replaces several stages of mechanical cells. SlamJet spargers are removed without draining the column, shut on supply gas failure and also retrofit to other flotation columns.

HydroFloat floats particles up to 4 mm at 50 to 60% feed solids, and its feed needs pre-classification.
