Colortronic North America Inc. of Flint, Mich., has broadened its upstream product line of blenders and dryers within the past 18 months, said Keith Larson, manager of sales and marketing.
The products focus on specialized processes, particularly for powders and additives.
The high-end GraviPlus system targets the extrusion market.
The GraviPlus continuous loss-in-weight dosing and blending system can meter color and additives down to the lowest tolerance level without affecting the end-product quality. Previously, the GraviPlus line was known as GraviBlend.
Separately, Colortronic introduced at NPE in Chicago the C-Flex M flexible wall feeder for dosing powders, pellets, granulates, regrinds, fibers and flakes in either continuous or batch process.
Massage rolls provide feeding ease and avoid abrasion to the hopper. A compact design allows for arranging several feeders for multiple-feeder configurations. The C-Flex M can be integrated into a gravimetric or volumetric system.
Colortronic is a business of Schaumburg, Ill-based ACS Group.
