Dings Magnetic Group Stationary Electro Overhead Magnets - Manual (Page 6)

Revised January 19, 2011
INSTALLATION
An electro overhead magnet is built in 2 types: Inline and Crossbelt. An Inline type is installed
over a conveyor head pulley so that the single turnbuckle parallel to the travel direction of
material falling off the conveyor. The head pulley must be made from non-magnetic material.
A Crossbelt type is installed over a conveyor so that the single turnbuckle side of the magnet
at a right angle to the travel direction of the material on the conveyor.
Magnetic performance may be affected by magnetic material in the field. This includes such
items as I-beams, metal supports, hoppers, or splitters. These and other ferrous objects need
to be kept out of the magnetic zone.
Crossbelt Suspension Inline Suspension
Suspension height is critical to the performance of the magnet. This distance is measured from
the bottom of the magnet face to the surface of the material handling belt.
The magnet should be mounted at the recommended suspension height. IF MAGNET IS TOO
HIGH ABOVE BURDEN, SUFFICIENT MAGNETISM MIGHT NOT REACH INTO THE
BURDEN. TOO MUCH HEIGHT WILL CAUSE A LOSS OF SEPARATION EFFICIENCY. For
best results, crossbelt separators should be centered over the belt and parallel to the slope of
the belt conveyor.
