The principle of drum shredding is a high speed of a working tool (a chain, which is as a working equipment inexpensive and easily replaceable) in a enclosed workspace of the shredder (thick-walled metal tube). In this tube a rotating chain hits at high speed into a shredding material so the material is mechanically shredded. As a result is high efficiency shredding and separating various materials or disrupting of their structure.
These shredders are suitable solely for shredding:
- composite (multiple-layer and multiple-species) materials, such as; electro waste, electro motors, recycling of refrigerators,
- aluminium waste - mainly it is a recycling of cars radiators and catalysts (to get the precious metals contained inside of them),
- heavy magnesium cubes – to get an aluminium parts out of them (magnesium is broken into powder and aluminium pieces are then separated easily).
- They are used as a main component of recycling lines.
