Continuous gravimetric feeder line offers fast delivery times

Coperion K-Tron expands the original ProRate feeder portfolio with a completely new and cost-effective feeder line called ProRate Plus.

The ProRate Plus continuous gravimetric feeder line 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 line features a design that allows a 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 5-ft radius. The three feeder models Plus-S, Plus-M, and Plus-L cover a range of throughputs. The feeders are capable of handling feed rates from 0.12 to 400 cu ft3hr, depending on the material. Theoretically a feeding system with six ProRate Plus-L feeders can feed up to 1,017 cu ft/hr on a footprint of only 75 sq ft2.

ProRate feeders are highly standardized and include a variety of design features to optimize performance and ease of use. Simple access for cleaning and maintenance, even within a cluster, is provided thanks to a patent-pending rail system called “ProClean Rail.” ProClean Rail makes it possible to retract the base unit toward the rear of the feeder and rotate it for access to the feeding section and screw element. This allows for maintenance and cleaning of the feeding unit while keeping the feeder in position. In addition, the bellows and screw use the latest magnet technology for simple but robust mounting. The magnet connections allow these parts to be released without tools while, at the same time, providing the required holding force for optimal and safe operation.

Thanks to the high level of standardization of the feeders, the number of spare parts required for emergency stock is minimal. Many parts are identical for all three models and can be used as exchange parts for all devices.

ProRate Plus feeders are suitable for use in hazardous locations rated NEC Class II, Div. 2, Group F & G and ATEX 3D/3D (outside/inside).
