Microfeeder and Compact Feeders for low rate feeding
Microfeeders can attain the lowest rates for high accuracy micro ingredient feeding while Compact Feeders offer a low rate solution that fits easily in limited spaces, laboratories and pilot lines
NEW! MT16 Loss-in-Weight Microfeeder
Coperion K-Tron’s NEW low rate, Micro-ingredient Feeder has been expanded to include interchangeable MT12mm and MT16mm twin screw feeding modules or MS12mm and MS16mm single screw feeder modules. Overall feed rate capacity is from 0.02 dm³/hr to 27 dm³/hr.
The new Micro-ingredient Feeder is ideal for applications feeding high value / high cost additives in any food, pharmaceutical, plastics and chemical process that require second to second performance with a high degree of accuracy. The interchangeable twin to single screw feed modules provides versatility to handle a broad range of materials from powders to granular.
The unit has a smaller overall profile and footprint allowing for closer discharge dimensions, and is ideal for multi-ingredient cluster arrangements. The design also allows for extended screw profiles. The unit is easy to take apart, clean and maintain with a totally enclosed weight sensor and drive motor with improved higher torque for handling difficult materials. To learn more, Download Flyer.
Compact feeders are avaialable in volumetric and loss-in-weight models, with single screw, twin screw or vibratory tray metering devices. With the variety of metering configurations available, Coperion K-Tron's Compact Feeders are able to handle a wide range of bulk solids, from free flowing pellets to difficult powders or fragile materials.
Compact feeders are used where headroom is a problem, or where a process requires high accuracy at low feed rates. Feed rates range from 0.07 - 313 dm3/hr (0.003 - 10 ft3/hr).
Both the single screw and twin screw Compact Feeders offer interchangeable feeding tools, which provides the flexibility to handle a variety of bulk materials. All parts in contact with the bulk material being fed are stainless steel. Feeding equipment is easy to dismantle.
The screw feeders employ a horizontal agitator that gently moves bulk material to the large throat and into the discharge screws. For all loss-in-weight models, the scale housing is completely enclosed.
Micro Cone Feeder
The Coperion 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 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.
