Pitman, NJ — The K-Tron Process Group will introduce the K-Tron Colormax Multi Weigh gravimetric blender to the U.S. Plastics Industry at the June 19-23 National Plastics Expo (Booth 1158). The K-Tron Colormax Multi Weigh blender offers the plastics processor high accuracy blending and synchronized screw-less feeding for up to four different materials using the patented technology of the Colormax Posimax feeder.

The Posimax feeders, like K-Tron's Bulk Solids Pump™ (BSP) feeders, are designed with vertical rotating discs which create a product lock-up zone, conveying material smoothly from storage hopper to discharge outlet. Synchronized feeding of all components ensures a constant blend is achieved, avoiding layering and the need for an additional mixing device. The Multi Weigh blender can incorporate the Posimax B200 feeder, with a maximum feedrate of 150 kg/hr, and the Posimax B350, with a maximum feedrate of 500 kg/hr, allowing the Multi Weigh to address applications up to 2000 kg/ per hour.

The Multi Weigh Gravimetric Blender is designed with noise resistant digital weighing and a Perspex hopper, allowing for visual flow check. The easy-to-use control system incorporates a number of standard control routines, including calibration, starting an empty blender, and emptying a unit for a production change. The Multi Weigh controller runs the loss-in-weight feeders and sequences up to four vacuum loaders and a vacuum pump. By monitoring the material usage of each feeder, the loader priority is automatically set to ensure that the highest throughput material receives the highest priority for refill.

Up to twenty recipes may be stored for different product formulations or alternatively material percentages for color, additive, and regrind can be entered directly. Typical applications for the Multi Weigh gravimetric blender include single screw extrusion processes, pipe and profile extrusion, blown film lines, cast film lines, injection molding machines and central blending station.
