Niederlenz, Switzerland (January 2022) – Coperion K-Tron is proud to announce the expansion of the original ProRate™ feeder portfolio with a completely new and cost-effective feeder line called ProRate PLUS. Answering the call from the marketplace for a robust and reliable feeder for simple feeding applications in the plastics industry, Coperion K-Tron developed a completely new feeder line built on 100 years of feeding experience. The ProRate PLUS continuous gravimetric feeder line is an economical solution and offers a quick return on investment due to its good price-performance ratio and fast delivery times. It was designed with the specific requirements of the plastics processing industry in mind. These single screw feeders are ideal for the feeding of pellets, granules and other free-flowing bulk materials in secondary plastics applications. ProRate PLUS feeders are available in three sizes and can be installed as individual units or easily arranged in cluster of up to six feeders around a process inlet, depending on the recipe formulation.
The ProRate PLUS feeder line features a unique design which allows a very compact, space-saving arrangement. The trapezoidal shape of the ProRate Plus feeders allows up to six feeders to be easily grouped around an extruder inlet within a 1.5 meter [5 ft] radius. The three feeder models PLUS-S, PLUS-M and PLUS-L cover a wide range of throughputs. The 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. Theoretically a feeding system with six ProRate PLUS-L feeders can feed up to 28.8 m3/h [1017 ft3/h] on a footprint of only 7 m2 [75 ft2].
