Shredders for Metals Recycling

Shred through the toughest compressible materials

Hammer Mills


Our hammer mills are the answer to the challenge of selectively shredding hard and brittle materials. 
Hammer mills also take the pelletization of rubbery materials – as preparation for downstream separation systems – in their stride.

A tough customer?
Just so.
ERS hammer mills are especially suited to metal, electrical and electronic scrap or swarf from steel or aluminum – and many other materials besides. Simple adjustability during operation also makes short work of the pelletization of non-ferrous metals. The final fragment size is variable and can be changed during operation. That’s also a great example of the product’s flexibility in catering to a wide range of applications.

Technical features:

• Extremely hard-wearing, separate grinding elements and inner lining – replaceable
• Fully-enclosed construction, dust-tight construction guaranteed by special shaft and housing seals, plus corresponding extraction points
• Mechanical overload protection with emergency reject mechanism in case of solid materials and contaminants
• Housing wall pivots hydraulically to enable easy access for maintenance and inspection work
• Inert atmospheres possible using nitrogen or other gases
• Application-specific drive and grinding element models
• PLC control unit with automated power down and optional frequency-driven motor speed controller

The flexible design of the rotor-stator principle, adapted to the different materials being processed, can be installed both for the breaking-up of materials and as ball-forming machine, offering therefore a wideranging scope of applications:

• Processing of electronic waste as a preliminary stage or a subsequent stage after the customary ripper technology
• Processing of aluminium profiles and composite materials
• Preparation of shredder light fraction for subsequent separation
• Recycling of printed circuit boards, IC components and small electronic equipment
• Grinding of non-ferrous composite materials with subsequent ball forming
• Processing of large-volume metal swarf
• Preparation of tyre wires for subsequent separation of rubber and iron
• Slag processing
• and much more...
