The HV 70 plastcompactor from Herbold Meckesheim processes a wide variety of materials into products of high bulk density in continuous operation between one rotating and one fixed compactor disk, each equipped with screwed-on and easily replaceable kneading bars. Since the material leaves the compactor zone within fractions of a second, the thermal impact upon the plastic is very low. The process is regulated using two parameters – the screw speed and the distance between the disks.

The SML 60/100 SB 2 from Herbold Meckesheim is a granulator suitable for dry and wet operation with horizontal forced feeding, which allows space-saving installations and easy feeding of the material. Another advantage is the high throughput capacity thanks to a one-meter wide inlet from the hopper and 50-centimeter strong feeding screws that transport the material to be ground to the rotor. Seven rotor knives and now also an optional third stator knife allow up to 21 cuts per revolve.

The HVST 120/120 step dryer is ideally suited for regrind or granulates of all thermoplastics and is especially recommended for PET and other hard plastics. As a central component of washing lines from Herbold Meckesheim, the HVST reduces material loss due to fines formation compared to conventional centrifugal dryers thanks to the multi-stage, gentle and, moreover, energy-efficient process. Residual moistures of far less than one percent can be achieved with this step dryer.
