Magnetic
Conveyor eliminates problems associated with Belt Conveyors |

The Problem:
Handling ferrous scrap can be a problem for any metalworking
shop, but when you are the largest manufacturer of automobile
and truck frames, the problem takes on enormous proportions.
At A.O. Smith Corp.'s Automobile Division, 1,200-ton Danly
coil blankers operate around the clock stamping out automobile
front cross bars. In the process, each creates up to 2,400
pounds of scrap per hour in the form of 1/8" thick round
and oblong mild steel slugs, ranging in length from 1/4"
to 6".
A.O. Smith's plant originally used a metal belt conveyor to
remove scrap from beneath the presses, elevate it and discharge
into a hopper. But slugs would often catch in the hinged belt,
jamming the conveyor and causing a conveyor and press shutdown.

The Equipment:
Eriez Magnetic Chips and Parts Conveyor

The Solution: Because of the lost production
time and high maintenance cost involved with the metal belt
conveyors, the conveyors were replaced with two Eriez Magnetic
Chip and Parts Conveyors.
Eriez' permanent magnetic conveyors use a continuous series
of powerful ceramic magnets to pickup and glide material
along the stainless steel slider plate. Material is then
discharged over the head end. Because of their liquid-tight
construction, lower conveyor sections can be completely
submerged in coolant sumps or tanks. The working face is
self-cleaning, and excess fluids drain easily back into
the tank. The unique Eriez' Tuf-Trac drive system eliminates
the need for oil inside the housing. The drive chain rides
in oil impregnated UHMW track, designed to operate quiet
ely and maximize conveyor life.
As slugs drop from the press onto the conveyor surface,
they are held by the magnetic field and slide up the 14-long,
60° incline where they are gravity-discharged into a
hopper.

The Result:
The Eriez Magnetic Conveyor design and construction enables
A.O. Smith to produce at full capacity with zero downtime.
Except for an externally mounted drive motor, the unit is
self-contained, and the conveyor mechanism is completely enclosed.
There are no moving parts to jam, break, or endanger personnel.
What that all means to A.O. Smith is that its presses are
more productive because the Eriez conveyors remove the scrap
without interruption.
