Combined Version of Shredder AND Granulator: The HERBOLD Granulator of the
The advantages of a single-shaft shredder are well known: it is possible to fill a feed hopper which is then gradually emptied by means of a hydraulically operated ram without the assistance of operators: due to its special design, the rotor only “nibbles” at the material that is fed via the hydraulic ram.
Until now it has not been possible to obtain small granule sizes with these shredders: often a 15 or 20 mm-screen has been the lower limit, making intermediate conveying and a secondary granulator necessary in order to achieve smaller granule sizes ranging from 4 to 8 mm and a satisfactory throughput.
Now it is possible in one single size reduction step with the HERBOLD granulator of the
HB series. The design of the HERBOLD HB granulator is a combination of a feed hopper and a hydraulic ram with a granulator. Due to the special design of the grinding chamber and the high cutting frequency, it is now possible to transform bales, cut open film rolls, mingled packs of sprue spiders, but also extremely large and thick-walled purgings into the finished product in one single step.
Also bulk hollow bodies, e.g. whole IBC containers and rainwater collecting basins can be processed with this machine in a particularly economic way. An intermittent feeding of large quantities of material (e.g. a great many of bottle crates) is therefore possible without the necessity of dosed feeding or the risk of jammed material in the grinding chamber. Once the material has been fed and the hopper filled, no operators will any longer be necessary, thus enabling a semi-automatic operation.
The main advantage of this new development is its space-saving design since only one size-reduction step is necessary.
