Description

The NXT:GRAN continues to combine size reduction, feeding and extruding into one extremely efficient work step (ONE-STEP technology). In doing so, it draws upon the experience gained from having over 1000 patented shredder-feeder-extruder combination installations worldwide.

The NXT:GRAN offers maximum performance in all areas. Zero-waste production between input and output guarantees that the full value of the material is preserved. At the same time, as with all NGR technologies, input of work and energy are reduced to an absolute minimum.

The operating principle of NXT:GRAN

Using the material efficiently in each work step: The patented shredder-feeder-extruder combination provides maximum performance for extremely high output and quality.

First, the materials being fed are pressed against the solid shredder shaft by the hydraulic pusher. The shredded material is then conveyed into the extruder by the revolutionary Duo-Direct feeder. Both of these process components feature load-dependent and fully automatic control.

In the extruder, the polymer is efficiently melted and homogenized, and, if necessary, the melt is vacuum degassed at the same time. The shredder outlet and extruder intake components are placed close together so the heat generated in pre-processing is transferred into the extruder. This design feature optimizes the energy balance and gives the NXT:GRAN extremely efficient operation.
