K-Tron Micro Cone Feeder...a screw-less design for low rate additive feeding
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.
Design
Utilizing a simple induced flow rotating cone, the Micro Feeder is designed to dose down to a few granules at a time and up to 2 dm3/hr (122 in3/hr or .07 ft3/hr) of normal masterbatch. 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. Easily damaged or low melt point additives are also protected from degradation.
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°) to discharge material in a non-process direction.
A low power stepper motor drive and controller provide excellent turndown and flexibility ensuring a wide operating range.
