K-Tron FeedersSmart feeding solutions for dry bulkmaterial and liquid process controlOverview

Feeding by Volume withK-Tron Modular FeedersEvery FeederStarts as aVolumetricFeederIn principle, volumetric feedingis the simplest, most economicalfeeding solution available. Bulkmaterial is held in a hopper andconstantly fed into a process perunit of time. A gravimetric feedrate may be inferred through acalibration process where a timedsample is taken and weighed,and screw speed adjusted accordingly.Although there isno weight feedback to assurefeeding accuracy over time,this may not be a concern formaterials with consistentbulk density.Bulk Solids PumpFeederChoosing the Best Volumetric Feeder for Your ProcessK-Tron offers a wide variety ofsingle and twin screw volumetricfeeders as well as Bulk SolidsPump TM feeders.With exchangeable screw designchoices, screw feeders canhandle a wide range of applicationsinvolving prefeeding, feedingor batching of materials withconsistent density, particle sizeand moisture content.Single Screw Feedershandle free-flowing materialssuch as pellets and powders.Twin Screw Feedershandle more difficult materialssuch as pigments, sticky, bridgingor flooding powders, fiberand fiberglass.Bulk Solids Pump Feedersare designed for gentle andprecise feeding of free flowingpellets, granules, flakes, powdersand other friable products.ModularSingle ScrewFeederModularTwin ScrewFeederModular design of screw feeders allows for easy disassemblyand fast cleaning2

Feeding by Weight withK-Tron WeighfeedersGravimetricFeeders Offera Windowinto YourProcessIn gravimetric feeding, dry bulkmaterial or liquid is fed into aprocess at a constant weightper unit of time since weight is avariable that can be captured bya weighing module. Consistentcontrol and complete monitoringare possible.

The resonant frequency is measured to determinethe weight. In K-Tron’s patented Smart Force Transducer(SFT), the signal is directly converted into a digital weight signalby a built-in microprocessor. The signal is then communicatednoise-free via RS 485 to the controller.Each weighing module is linearized and temperature compensatedduring manufacture. The resulting information is burnedinto an on-board EEPROM located within the module to ensurevery high weighing accuracy throughout the unit’s entire operatingrange. Every SFT provides a true 4,000,000:1 weight resolution in80 ms and comes with a 5 year warranty.High accuracy Metering, Lower cost alternativegravimetric monitoring or for feeding pellets (singlefeeding of totalization of bulk feeder).

Typical Feeder ApplicationsSmartConnex TM :A Network of Thinking FeedersSmartConnex more tightlyintegrates the basic componentsof the feeder system – mechanicaldesign, control architecture andweighing technology – to greatlyreduce cost of installation and dailyoperation, while making the systemeasier to use and maintain.A key component is the K-Tron ControlModule (KCM). It combines motordrive and control unit func tionsinto a small box that mounts directlyon the feeder to create what K-Troncalls the first “Thinking Feeder.” TheKCM serves as the feeder’s “brain”and can control the feeder for batchand continuous processes.Twin screw modular feeder in snack food extrusion process.Modular volumetric and loss-in-weight feeders integratedwith a gravimetric blending system and K-Tronreceivers in a plastics extrusion process.7

Premier PneumaticsPneumatic Conveying Systemsand Components for Bulk Material HandlingOverview

Bulk Material Handling SystemsThe K-TronDifferencePneumatic conveying represents the core of a Premier Pneumaticsbulk material handling system. Whether it’s a simple system orachieving great performance with difficult materials, our applicationknowledge and ability to effectively handle a large variety of materialshave earned us the trust of our customers.Bulk Unloadingand StorageSystemsA bulk unloading and storage system can increase production and plant efficiency while decreasing labor,material and energy costs. Premier has time-proven capability to tailor an unloading and storage systemto meet specific applications. Consideration to plant layout, how material is received, the material’scharacteristics and conveying distance and rate are taken to ensure maximum system performance tohandle materials such as wood flour, PVC compound, cocoa, dextrose, titanium dioxide, soda ash, calciumcarbonate, sodium benzoate and many more hard to handle materials.Bag UnloadingPremier’s sack dump station traps dust generatedfrom the unloading of material received in bags. Inaddition to the vacuum system, the sack dump stationcan introduce material into pressure systemsor directly into a screw conveyor or mixer.Truck UnloadingThe PD truck unloading system includes a truck fillalarm panel located at the storage tank. A manualhose switch station lets the operator select thedestination.Railcar UnloadingThe PD railcar unloading system includes a blower packageand PLC controls to monitor the system’s operation.A single-blower system conveys material from the railcar tothe storage tank. One blower powers both sides of the system,minimizing cost. It is ideal for applications where the vacuumside of the system is a short distance.Dual-blower systems unload material from the railcar at higherconveying rates and for longer conveying distances.2

Weighing andScaling SystemsA continuous vacuum or pressure system can improve the accuracy and efficiency of your major, minorand micro ingredient handling. Maximum system performance is achieved by taking into considerationfactors such as plant layout, material delivery, material characteristics, batch size and the required conveyingrates. System controls can include recipe, formula and inventory capabilities. Materials of constructioninclude stainless steel for sensitive or sanitary applications as well as epoxy-coated carbon steelor aluminum for general applications.Loss-in-Weight Feeder RefillSeries 2400 and P-Series vacuum receivers andloaders can be used to refill feeders used incontinuous or batch applications. A number ofoutlet designs and discharge valves are availabledepending on the application.Batch WeighingA receiver is mounted on load cells to allow eachbatch to be “check-weighed” before processing,minimizing material waste and “off-spec” products.Self-cleaning filter media eliminates product carryoverand provides a cleaner process area.Scale Hoppers (Vacuum or Pressure)Material can be delivered to the scale hoppers bya closed-loop Aeropass system, filter receivers,cyclones or screw feeders. When a receiver is used,an Aerolock meters material into the scale hopperuntil the set point is reached.Filter Receiver Scaling (Vacuum or Pressure)Material is conveyed to a filter receiver mountedon load cells. The receiver’s self-cleaning filtermedia separates the material from the conveyingair, eliminating product carryover and providing acleaner process area.3
