Extrusion International 3-2025

26 Extrusion International 3/2025 INDUSTRY NEWS processes such as mechanical recy- cling of post-industrial and post- consumer waste, chemical recycling, PET recycling or solvent-based recy- cling. Especially for recycling of post- consumer recyclate (PCR) or any highly contaminated polymer, Co- perion offers the innovative ZSK FilCo filtration compounder that allows filtration and compound - ing in a single production step. Compared to the two-step produc- tion lines that have been the norm until now, Coperion’s ZSK FilCo is distinguished by a markedly more streamlined equipment set-up. En - ergy consumption and emissions for the extrusion process are reduced by more than 50%. Robust, Flexible and Precise Feeding Solution: ProRate PLUS The ProRate PLUS feeder line integrates state-of- the-art European weighing technology and controls, ensuring high accuracy and reliability in loss- in-weight feeding pro- cesses. This line meets the growing demand for robust and efficient feed - ing solutions in the plastics industry. The ProRate PLUS continuous gravimetric feeder line is an economi- cal solution and offers a quick return on investment due to its good price-performance ratio and fast delivery times. The ProRate PLUS feeder line fea - tures a space-saving trapezoidal shape which allows up to six feeders to be easily grouped around an ex- truder inlet within a 1.5 meter [5 ft] radius. Three single screw feeder models PLUS-S, PLUS-M and PLUS- L along with the PLUS-MT twin screw model cover a wide range of throughputs and bulk materials. ProRate PLUS feeders are capable of handling feed rates from 3.3 up to 4800 dm3/h [0.12 up to 400 ft3/h], depending on the material. Theo - retically, a feeding system with six ProRate PLUS-L feeders can feed up to 28.8 m3/h [1017 ft3/h] on a foot - print of only 7 m2 [75 ft2]. Smart Feeding Solutions In addition, Coperion demon- strated its expertise in all feeding tasks at this year’s Chinaplas with its high-accuracy Coperion K-Tron K2-ML-D5-T35 gravimetric feeder equipped with ActiFlow™ smart bulk solid activator and EPC (Elec - tronic Pressure Compensation). The feeder is equipped with a 2415 vac - uum receiver for refill. The ActiFlow™ smart bulk solid activator offers an innovative meth- od to reliably prevent bridging and rat-holing of cohesive bulk materi- als in stainless steel hoppers without internal hopper agitation. The smart flow aid applies gentle vibrations to the hopper wall, hereby carefully activating the contained material with the optimal amplitude and fre- quency, automatically adjusted by the controller based on bulk mate- rial flow. It is designed specifically to work with Coperion K-Tron’s line of gravimetric loss-in-weight feeders. All-around worry-free service Coperion conducts its intensive research & development work both for new plants and for their integration into existing systems. For this purpose, Coperion offers comprehensive maintenance and modernization packages for all its technologies, which increase the productivity, flexibility and reliabil - ity of the plants to a significantly improved level. Such services allow plant operators to fully exploit the improved performance potential of the plant after shortest time.
