REQUIREMENTS, SPECIFICATIONS
AND TECHNICAL DATA

The stated requirements were to design and build a magnet capable of removing large ferrous particles from copper ore which has been crushed to 10" (254mm) in size.

The capacity as specified was to treat 8400 metric tons per hour from a 3150mm (124") wide feeder. Conveyor travelling at a speed of .33 meters per second (65 feet per minute). The load height or depth of material on the conveyor is estimated to be 1600mm (63").

The magnet will be suspended over the end of the conveyor where the material is estimated to be 254mm (10") thick. The magnet is to be installed at an elevation of 10,000 ft. (3050 meters) above sea level at a copper mine located in Chile.

Since the feeder conveyor carries a uniform depth of material between the side skirts confining the material, the magnet was designed to provide a magnetic field to match this width.

To accomplish this, the magnnet designed with copper coils had to be wider than the feed conveyor and large enough in the direction of conveyor teavel to produce the field strength at the suspension distance to remove the large particles.

The magnet is 3505mm (138") wide by 3048mm (120") long and nearly 2438mm (96") high and weighs 88.5 tons when filled wtih trandformer oil to dissipate the hear generated by the coil.

The unit contains some 40,000 lbs. of conductor, some 24,000 lbs. of transformer oil, and 113,000 lbs. of steel and manganese. It surpasses the previously designated World's Largest Suspended Magnet by nearly 22.5 tons.
