Shredder AVZ

Our ADELMANN Pre-shredder (AVZ) is a universal shredder system consisting of a robust machine housing and a cutting mechanism which uses two parallel cutting shafts which are driven by a counter rotating mechanism.

The cutting blades are firmly attached to the cutting shafts and are fitted with feed hooks They rotate past each other with little clearance, cutting the material with their edges. By choosing the right relationship between the width of the cutting blades to the number of hooks per blade it is possible to obtain a precisely defined shreeded result, which in a later process, ca be separated into specific sizes using a sieve.

The core mechanism is fitted to the cutting shafts using a rigid coupling an d mounted using dampers in order to compensate for the torque caused after processing obstructive material.

Outages caused due to swapping worn cutting shafts are reduced to a minimum by quick change coupling. This allows the complete cutting shaft to be taken out of the machine housing in a few steps without the effort of removing the cutting blades and bushings.

Then new cutting shafts are placed into the machine housing and are bolted in. The machine can be started within a short amount of time.

An even feed of material is guaranteed by differing the rotational speed of the cutting shafts. This results in an off-set of the material feedi hooks preventing the material that has to be shredded from “dancing” on top of the cutting shafts.

Optionally a hydraulic mechanism to push heavier materials, such as furniture or large tyres, into the cutting unit. The shredder can still be retrofitted later. Depending on the usage scenario there are a number of different machine sizes, motors and cutting blade widths available. Our specialists are happy to advise you to select the correct machine model.
