A continuous loss-in-weight feeding system and a gravimetric additive feeder are new from ACS Group, New Berlin, Wis. Both are available from AEC Inc., Schaumburg, Ill., Sterling Inc., New Berlin, and Colortronic North America, Flint, Mich.
The AccuMeter continuous loss-in-weight feeding system (right) for extrusion, compounding, and blow molding replaces the OL blender system. It comes with new Allen-Bradley CompactLogix PLC and PanelView Plus 10.5-in. color touchscreen as standard. Also standard is integrated refill of the weigh hoppers (for up to 40 refills/hr). The modular system handles two to eight ingredients and allows you to mix and match feeder types for pellets, powders, and liquids; choose digital or analog load cells; and modify the system in the future if necessary. (When digital load cells are used, the system comes with the Colortronic C2 proprietary control system.)
The system uses static blending as the streams of ingredients cascade together in the blend hopper. AccuMeter comes in three versions: AMC for general compounding, including wood/plastic lumber and masterbatch; AMP for blending pellets and/or regrind with additives; and AMF for blending very low-rate additives, such as colorants on a fi ber line. AccuMeter can feed from 50 g/hr to 16,500 lb/hr with a cumulative dosing accuracy of ±0.5%.
Also new from ACS is a gravimetric additive pellet feeder, designated AEC AF-1000, Sterling SF-1000, or Colortronic CF-1000 (far right). The self-calibrating feeder can connect via integral TCP/IP card to the injection machine or can have online flow-rate control (in % or kg/hr) for use with extruders. Special software is available for blow molding. The screw feeder comes with a graphic display and keypad; pneumatic loader is optional.
