Our most rugged hammer mills are designed to serve the scrap metal industry. More and more scrap yards are discovering that by breaking up mixed metal or “contaminated” components and sorting to obtain a “clean” metal product, the value-added benefit is well worthwhile. Breaking up transformers, motor windings, generators/alternators, aluminum castings, plumbing fixtures and all manner of mixed metal/plastic components requires a Heavy Duty machine, designed for continuous use. The design of these machines includes oversized bearings, shafts, interior armor, and thickness of the casings. External stiffeners are added for rigidity and the design of the casing provides a direct impact of the fed material to promote breaking apart rather than grinding or pulverizing. Selecting the right screen size allows the broken pieces to discharge after the dissimilar metals/plastics are separated. Popular screen sizes range from 1/2″ slots or holes up to 4″ x 4″ holes.
Separating copper motor windings (stators) or transformer windings from laminated steel pates is a popular use of our HD hammer mills. The 34″ x 24″ HD hammer mill is rated to accept feed of this type of loosely-held material at up to 20lbs per piece. The 24″ x 16″ HD hammer mill is good for up to 6-8 lbs per piece. We recommend that heavy-sectioned material such as whole starters/motors, small gas engines, or plumbing fixtures be limited to a lower weight.
