New low rate feeder to be introduced at K-Show

September 24, 2007

K-Tron will introduce a new Micro Cone low rate feeder at the K-Show in Düsseldorf, Germany, October 24-31. The K-Show (K for Kuntsoff-- the German word for Plastics) is the biggest plastics show in the world. The Micro Cone Feeder will be exhibited as one of four feeders on a K4G gravimetric blender to be exhibited in the K-Tron booth in Hall 10, Stand A74. The K-Tron Micro Cone Feeder features a highly innovative screw-less feeding mechanism to accurately dose free flowing color, Masterbatch or additives into a blending system or directly into the process screw of an extruder. Utilizing a simple induced flow rotating tube or cone, the Micro Cone Feeder is designed to dose down to a few granules at a time, with a feed rate range of 0.02 to 6 dm³/hr (0.007 to 0.07 cu ft). With use of an extension tip, the feeder can feed as low as 0.1 dm³. The minimum dispersive rate is > 2 pellets per second. With no pockets or screws, the design is simple, providing ease of use and almost zero maintenance. The feeder housing swings open for fast material change. There are practically no areas for the product to trap so cleaning is very easy. Reliability is assured with few parts and very little strain on any one item due to the low friction of the system. The inlet slide gate allows for material shut-off and removal of the feeder for cleaning and hopper emptying. The feeder can also be mounted in opposite discharge position (180 degrees). A low power stepper motor drive and controller provide excellent turndown and flexibility ensuring a wide operating range. The Micro Cone Feeder has been undergoing Beta testing at locations in Europe and the USA over the last year.
