MRS - Material Recycling System

Closed loop - save processing of CD/DVD sprues

The production of prerecorded/recordable/rewritable optical media (CD, DVD & smart cards) generates tons os so-called "sprues" annualliy.

The usual way to dispose of this production wastes is collection, storage and finally dispatching to a raw material supplier. This Material Recycling System (MRS) recycles these sprues in a closed loop process: The MSR unit collects sprues directly from the moulding machine, grinds them and re-injects them with the "virgin" polycarbonate (PC).

The closed loop system prevents impurities from mixing with the recycled polycarbonate and therefore maintains the PC`s quality.

The benefits:

slow running granulator (280 rpm)
ideal granulate quality with very low dust
co-rotating rotor discs prevents material trapping between rotor and housing
special sieves guarantee constant grain size
quick sieve and knife change
no need to adjust the rotor knife
knives can be reground several times
external bearing, dust resistant
basin with connector for suction
almost maintenance-free
easy and fast handling
opening without tools
CE certified
