ProRate™ PLUS Feeders

Get in touch

A feeder that makes you wonder why we haven't invented it sooner.

Three size options, zero features you don’t need: The all-new ProRate PLUS is a feeder that may seem modest, but it shines when you use it for the first time (and, of course, every time after that). It’s a feeder that is simple to integrate, to fill, to operate, to clean. It is robust and reliable. It gets the job done, no matter what. The all new ProRate PLUS is a lot of things, but most of all, it’s surprisingly powerful.

Reliable feeding of free-flowing bulk materials in plastic processing applications. The ProRate PLUS Continuous Gravimetric Feeder Line has been designed with the specific requirements of the plastics processing industry in mind. The single screw feeders are available in three sizes are designed for free to moderate flowing bulk materials. Due to its compact design, the ProRate PLUS not only works as a single unit but also integrated into a cluster of up to six feeders which can be easily grouped around the same extruder inlet.

Available Models

A_ProRate_PLUS-S-V
ProRate PLUS-S Feeder

The ProRate PLUS-S feeder is designed for gravimetric feeding of free flowing bulk solids that do not require agitation. It is ideal for feeding pellets in the plastics industry. The single screw feeder with extension hopper is suspended on a single-point weighing system in a compact frame. Proven Smart Force Transducer (SFT) weighing technology provides accurate and reliable performance.

ProRate PLUS Technology

ProRate_PLUS_Load_Cells
P-SFT-II-L and P-SFT-II-M load cells

P-SFT Smart Force Transducer load cells, operating under compression, provide accurate, stable and reliable digital weight measurement under a broad range of operating conditions.

The P-SFT exploits the dependency of a vibrating wire’s resonant frequency on its tension to measure applied loads. Through mechanical means the applied load is transmitted to the wire, causing a change in its resonant frequency from which the weight of the applied load is computed by the onboard microprocessor. A fully calibrated (linearized, spanned and temperature compensated) signal is transmitted via RS 485 serial communication to the controller.

Features

  • Direct digital weighing
  • Onboard microcontroller
  • Excellent repeatability and stability
  • High tolerance to vibration and electrical noise
  • Electronic temperature compensation

A_ProRate_PLUS_PCM_models
PCM-KD controller with user interface and PCM-MD motor drive unit

With the ProRate PLUS control system each feeder has its own PCM control module, installed directly at the feeder. In a line setting, up to eight feeders can be controlled from one PCM-KD. Connection between feeders and operator interface is via an industrial network. All setup, diagnostics and operator interface functions are controlled via a the PCM-KD interface. With its tight integration into the feeder, the PCM can be pre-wired and pre-tested in the manufacturing plant.

Two models are available:

  • The PCM-KD features an operator interface with keypad and LCD display in addition to a motor drive for one feeder. The control and motor drive module are combined into one component and are integrated directly into the feeder. The PCM-KD also features simple line control functionality: up to eight feeders can be controlled from one PCM-KD.
  • The PCM-MD is a single feeder motor drive unit with no operator interface. The PCM-MD must be connected to a PCM-KD in order to control the feeder.

Configuration note: A single feeder must have a PCM-KD for feeder control functions. In a group or line setting with up to eight feeders one feeder in the group must be equipped with a PCM-KD, the rest just need the PCM-MD motor drive unit.
