This technique has the advantage that:
- The loading facility has the ability to take in over six cubic
meters each time.
- This large volume reduction means that this technique is likely
to make a real difference to the viability of baling bulky difficult
and low value materials like plastics.
- This technique has the potential to make a real difference
to putting together realistic volumes for better marketing of
these previously difficult to market materials.
- The mobile feature means that handling and transporting these
difficult to handle materials will be less of an issue.
The pressure is applied directly to both ends of the bale rather
than indirectly via a friction chamber. Two pairs of 200mm hydraulic
cylinders are mounted by their headstock within a central bulkhead.
The pistons are connected to the end gates by large channel drawbeams,
the stresses resulting from the final stages of compression are
very localised because all the thrust and lateral pressures are
contained within this centralised bulkhead.
It is this feature that gives the potential to go from 90% of
the overall chamber length down to possibly 15% of the overall
chamber length and makes it manageable for transporting and containing
this amount of muscle and weight.
