The Shredder is specifically designed for the effective pre-cutting of thick-walled, high impact pipe to a maximum of 1200mm diameter and 6M in length as well as for start up line scrap. Depending on the impact resistance and the wall thickness of the pipes, the machine has a maximum capacity of 3,000 kg per hour.
The pipes are laterally feed via a feed trough which is positioned in front of the shredder and the pipe is automatically pushed towards the shredder shafts with a 'load control' system (a ram driven by a geared motor via a steel cable).
Solid welded annealed steel construction with all bearings, gears drives and motors externally mounted for ease of maintenance and incorporating a Siemans Simatic S7 touch screen HMI.
The HZR 1300/4 shredder has 4 shredder shafts driven by 30kW motors using reversible blades supported on a V shaped profile on the rotor shafts. These features combined with a toothed stator blade ensure a consistent low impact cutting action.
The shredder is generally followed by a granulator for final size reduction of the material to a free flowing regrind. The main advantage of combining the shredder and regrinder in a two-step solution, compared to a single step solution is that energy costs are reduced by up to 50%.
