Rotorshredder (RS)

The do-it-all shredder

Our BHS Rotorshredder (type RS) crushes, untangles and disaggregates materials. The crushing tools exert an intense stress on the input material through a combination of impact, punching and shear forces. This results in selective size reduction with the following special features:

  • Particle sizes are reduced in a targeted manner
  • Composite materials are disaggregated
  • Hard and brittle materials undergo intense size reduction
  • Metals are separated and cleaned
  • Entangled materials are singled out

The crushing tools consist of several rugged impellers that are flexibly attached to a fast-rotating vertical shaft. They are durable and do not require any adjustment or sharpening. The machine operates in continuous mode. After reaching the desired size, the material leaves the machine immediately through grid segments which are designed accordingly. This eliminates unnecessary consumption of energy. Rotorshredders are primarily used in the recycling industry for treating all kinds of materials that contain metals, but they can also selectively crush commercial waste, wood, paper and other types of waste.

Example of the crushing process with a washing machine in the RS Rotorshredder

1. RS Rotorshredder at rest

2. During operation, the hammers are positioned horizontally and stabilized by centrifugal force.
Process graphic 2 shows how the tools ("hammers") are aligned horizontally and stabilized by centrifugal force during operation.
3. The feed is crushed intensively when it reaches the impact chamber.
Process graphic 3 shows how the washing machine enters the impact chamber and is crushed intensively by the tools.
4. In just a few seconds the selectively treated material leaves the chamber through the slotted grid.

The crushing ratio and the intensity of stress on the material can be adjusted. Three machine sizes are available. Two large maintenance doors provide easy access to the interior of the BHS Rotorshredder. The Rotorshredder can optionally be configured with a flywheel in order to avoid mechanical and electrical peak loads.

At our BHS technical center in Sonthofen, we can perform industrial tests on customer-specific materials using the Rotorshredder (type RS).

More than a million refrigeration units cost-effectively recycled

The BHS Rotorshredder has proven its worth in practice in the mechanical crushing of refrigeration units at the recycling company H.J. Hansen A/S in Odense/Denmark. Since its commissioning, the machine has processed more than a million units. The appraisal after five years is highly positive!

Recycling of resources in steel production

The slag formed during stainless steel production contains valuable raw materials which should preferably be fed back to the melt or intelligently reused. With a treatment plant at Outokumpu Nirosta in Krefeld/Germany ThyssenKrupp MillServices & Systems GmbH (TKMSS) has demonstrated that dry treatment of slag is significantly more economical and environmentally friendly than wet treatment. The central element of the plant technology is impact crushing.
