The Neue Herbold Shredder Type HZR 1300/4 is especially designed for the effective pre-cutting of thick-walled, high impact pipe up to a maximum of 1200 mm diameter, 6 m in length as well as for start-up lumps.

In general the HZR is followed by a granulator for final size reduction of the material to a free flowing regrind.

The benefit of the new HZR Shredder together with a second step granulator compared with a single step solution is that it will reduce energy costs by between 20% - 50%. Another advantage is the long lifetime of the tools. These two factors ensure that the HZR 1300/4 Shredder delivers very good cost efficiency together with quality of build.

Capacity:
Depending on the impact resistance and the wall thickness of the pipe as well as on the screen hole size. The capacity can reach up to 3 t/h with cutting tools in good working condition.

Feeding:
The pipes are laterally fed into the feed trough which is positioned in front of the shredder. The material is then automatically pushed towards the shredder shafts with a "load-control" system (a ram driven by a geared
motor via a steel cable).

Housing:
Solid welded steel construction, annealed and manufactured with a machined finish, equipped with external supports for bearings, drives, gears and couplings.

Cutting tools:
Profiled rotor shafts, V-shaped supports for the blades. Blades can be used on 2 sides, toothed stator blade.

Controls:
Siemens SIMATIC S7, touch-screen panel
