Washing and size reduction of highly contaminated PE and PP bottles
Such applications ask for new solutions in machine technology: the HERBOLD high speed shredder is a modified impact hammer mill that can cope with these problems.
Pendulous beaters are used as cutting tools: these are much more insensitive against foreign bodies due to their ability to avoid foreign bodies. Another advantage is their much quicker exchange in comparison to single- or two-shaft shredders.
The HERBOLD high speed shredder can be used as a dry or wet shredder. The high friction arising during the wet operation of the machine is a pleasant side effect that will considerably facilitate an intensive washing and at the same time will remove coatings, paint or labels.
If hollow bodies and bottles are ground, especially in the field of polyolefines, another advantage shows it effect: this material is not only highly contaminated with foreign bodies (e.g. steel handles of pales), but it is also extremely abrasive.
The HERBOLD high speed shredder does not need regular welding at the rotor or at the housing. Everywhere where wear shows, due to the exchangeable armoured plates, a quick exchange of the affected surfaces can be made. And the cutting tools of the HERBOLD high speed granulator are extremely cheap. In addition to this, the operating expenses of this machine are surprisingly economical.
