ProRate™ PURE Feeders/Blenders and ProBlend™ Mixers

As the material enters the processing machine, the volumetric ProRate PURE Feeder precisely meters pelletized color concentrates, modifiers or free-flowing additives into the raw material stream. Designed for modular flexibility, ProRate PURE feeders 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 PURE Feeder onto the pedestal.

ProRate PURE 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 PURE feeders are not CE compliant.

The ProRate PURE 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 PURE II features a precision-machined, stainless steel housing and auger to maintain exact tolerances for high accuracy feeding.

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

Coperion K-Tron ProRate™ PURE 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 ensure 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 PURE blenders are not CE compliant.
