MATERIALS HANDLING
The Coperion PET recycling system
material costs per kilo drop and return on investment is reached more quickly. Coperion retained the proven Do:Di = 1.55 ratio of outer to inner screw diameter, thus ensuring secure scale- up to other STS model sizes. The extruder is equipped with a high- power motor and a gearbox designed specifi cally for the high torque. Proven high-performance materials for the screw shafts ensure full torque transmission from the gearbox to the screw elements. The higher fi ll level in the process section is crucial to the improved compound quality that the STS 75 Mc Plus achieves. It reduces shear stress and melt temperature and improves mixing behavior.
A GENTLE HANDLING PRODUCT The result is extremely gentle product handling at high throughputs. since
the process section of the STS 75 Mc Plus is equipped with heating cartridges that generate heat energy- eff iciently where needed.

The K-Tron feeder off er maximum fl exibility Another essential Coperion solution on show at ChinaPlas was
its K-Tron K2-ML-D5-T35 quick change feeder equipped with an ActiFlow smart bulk solid activator and EPC (Electronic Pressure Compensation). The T35/S60 feeder is designed for applications requiring quick changeover of materials and convenience of fast cleaning. The QC feeder allows for fast removal of the entire feeding module with screws in place for replacement with a second unit. Twin and single screw feeding modules are also available.
The ActiFlow smart bulk solid activator off ers an innovative way of preventing bridging and rat-holing of cohesive bulk materials in stainless steel hoppers without internal hopper agitation. The smart fl ow aid applies gentle vibrations to the hopper wall, thereby activating the contained material with the optimal amplitude and frequency, automatically adjusted by the controller based on bulk material fl ow. The product has been designed to work with Coperion K-Tron’s line of gravimetric loss-in-weight feeders.
The 2400 Series vacuum receivers provide a high-capacity sequencing system primarily used where larger conveying rates or long distances are required, in applications with one or multiple destinations. They are designed to high quality standards for pneumatically conveying powder, pellets and
granular materials for most industries. Conveying rates range from 327 to 6,804 kg/h (720 to 15,000 lb/h).
