Coperion K-Tron

Quick and easy feeding of plastic pellets and granules

Designed for on-machine feeding and mixing, ProRate™ Feeders/Blenders and ProBlend™ Mixers are ideally suited for feeding mixed bulk material in plastics injection or extrusion feeding applications. The volumetric ProRate I and ProRate II Feeders can be combined with a simple Gravity Mixer or the more sophisticated ProBlend Mixer for metering an exact and constant material mix into the processing machine. Where higher accuracy is required, the ProRate Blender offers continuous gravimetric blending by adding a scale to each ProRate Feeder.

Little effort is required for adding or removing feeders to and from the process, making this modular system an asset for applications with a variable number of ingredients.

As the material enters the processing machine, the volumetric ProRate Feeder precisely meters pelletized color concentrates, modifiers or free-flowing additives into the raw material stream. Designed for modular flexibility, ProRates can be added or removed to adapt to changing requirements. If, for example, an operator starts metering one ingredient and wishes to add a second, simply bolt another ProRate Feeder onto the pedestal.

ProRate feeders come in two sizes and can be combined with the Gravity Mixer or the ProBlend Mixer base to deliver a material blend into the process below.

Please note that ProRate feeders are not CE compliant.

FEATURES

  • Selection of five interchangeable auger sizes
  • Cast aluminum housing
  • Modular carbon steel pedestal accommodating up to 4 feeders
  • Easy calibration
  • Quick material change with swing-away motor design
  • Microprocessor controller
  • Choice of 0.04 and 0.07 m3 [1.75 and 2.5 ft3] hoppers

The ProRate II is equipped with larger augers and hopper capacities to deliver the larger feed rates required for some applications. It can be mounted directly to the molding machine, extruder or to one of Coperion K-Tron’s line of mixers. Each ProRate II features a precision-machined, stainless steel housing and auger to maintain exact tolerances for high accuracy feeding.

Please note that ProRate feeders are not CE compliant.

FEATURES

  • Stainless steel housing
  • 6 in. square pedestal handles 2 ProRate II feeders and 2 ProRate I feeders
  • Easy calibration
  • Quick material change
  • Pedestal with sample port
  • Microprocessor-based controller
  • Choice of 0.07 and 0.14 m3 [2.5 and 5.0 ft3] hoppers

ProBlend_Mixer
Three ProRate Feeders on a ProBlend Mixer

Designed for use as an on-machine blender or for central station blending, the ProBlend precisely meters and mixes materials at various blend ratios. Using a compact hopper with an adjustable speed impeller, the ProBlend’s continuous mixing action consistently delivers homogeneous blending. Positions are provided for up to four high-precision ProRate Feeders that can simultaneously meter additives or colorants into the blending hopper. ProRates can be added or removed to accommodate future application requirements.

Please note that ProBlend mixers are not CE compliant.


FEATURES

  • Modular flexibility to add or remove feeders
  • Machine mounted or central station blending
  • Quick release clamps for no-tool cleaning
  • Simultaneous feeder operation

ProRate Gravimetric Blender consisting of four ProRate Feeders

Coperion K-Tron ProRate™ Gravimetric blenders consist of one to six ingredient feeders and a PLC controller. They are designed to continuously meter raw materials accurately into a central station hopper.
Each of the feeders operates in an independent, continuous loss-in-weight scaling mode to insure accuracy of each ingredient. The desired feed rate for each material can be  entered in as pounds (or kg) per hour, as a percent of the total rate, or as a percent of the virgin material.

Please note that ProRate blenders are not CE compliant.

  • One to six ingredient feeders
  • Individual scales per feeder
  • PLC controller
  • Create, store and edit recipes
  • Inventory and alarm history
  • Heavy-duty, DC motor drives
  • Cylindrically designed hoppers for fast material discharge and complete clean-out
  • Clear center station top allows view of feeding material
