Alternating Pole For the Agitation of Fe from Residue At 250mm Gap: - 10,000 Force Factor (Gauss sqd/cm). - 460 Flux Density Gauss At 25mm Gap: - 150,000 Force Factor (Gauss sqd/cm). - 1100 Flux Density Gauss Approximately Twice The Magnetic Force Compared To Comparable Electro-magnetic Solution. Non-Deteriorating, Focused Field As Compared To Comparable Electro-magnetic solution. Better performance across entire drum width as compared to electromagnets. Less wear on drum surface and drive system as compared to rare earth magnetic systems, and the same or higher magnetic force at the working gap - where the force is most needed. Includes: - Manganese Drum Shell - Wear and Impact Resistant. - Bearings: Cooper Split Bearings. - End Flanges: Heavy-Duty Non-Magnetic Stainless Steel. - Side Anti-Spillage Rings: Heavy-Duty Non-Magnetic Manganese Steel - Plate Wheel - Lifting Points Please Add: $14,500 USD For Base Frame, SEW Drive System With Heavy Duty Chain & Chain Guards. Please Add: $5,000 USD For Transit From UK MFG to US Destination.
