Waste in different sectors is often too large to be recycled in one go and therefore needs to be reduced in size. In such cases, a professional size reduction machine from Pols offers the solution. With us, a distinction is made between two types of size reduction machines for size reduction, namely shredders and grinders. Both use different techniques for reducing the size of different materials. The latest shredder from top brand Doppstadt is the only shredder on the market with a roller that can turn in two directions. This ensures that, should the roller get jammed, it automatically reverses to clear the blockage. The grinders from Doppstadt reduce size with a rotating shredder. This results in fine pieces. Grinders are often used in the biomass sector and are available as both mobile and stationary units.
