Design Features

The K4G Blender System features a modular base plate, pivoting axle SFT-III support, central K4G collection hopper with pre-cut feeding ports, and a refill support stand with modular component build up. It accepts a wide range of Coperion K-Tron single or twin screw metering devices as well as Bulk Solids Pumps to handle a variety of pellets, granules, powders, flakes and fibers.

General cabling is inside protected conduits. Each system component is suspended from a single point and swings out on its axis, independent of any auxiliary devices. This allows for easy cleaning or replacement of equipment modules, e.g. the feeder screw, as well as for sampling.

The system is completely modular; feeders and conveyors can be exchanged or removed as needed. Each feeder is equipped with an individual SmartConnex control module featuring integrated support for single loaders.

Flexible Design - Various Feeder Options

The K4G system is completely modular - feeders and receivers can be exchanged or removed as needed.

The following feeders are available in K4G versions:

KQx4 Single Screw Feeder for low feed rates (see Single Screw Feeders)
