Volumetric Feeders, AccuRate Series
.. Volumetric feeding of bulk solids
.. Feeding without internal agitation
.. Gentle material conditioning
.. Economical and simple integration
.. Compact design
Application
Feeders of the AccuRate series are a special economical solution for volu-metric feeding of bulk solids.
With a feed rate range of 0.1 l/h to 8,000 l/h, these feed systems can be used for:
.. continuous feeding
.. batching and
.. blending
of materials with up to 10 mm grain size.
No matter whether materials or addi-tives are fed into the process, extrud-ers or compounders, or a blend re-quires to be formed, feeders of the AccuRate series offer the right solu-tion for almost any application.
Their simple, compact design does not only ensure easy service and main- tenance but also economical integration into existing production plants.
Features
The AccuRate basic feeder comes with the following features:
.. Housing (rugged welded struc-ture) of stainless steel, with easily removable side panels
.. Flexible hopper of (FDA-approved) TUFLEX vinyl
.. “Massaging” paddle system
.. Discharge unit (helix and nozzle in stainless steel)
.. Vertical discharge head
.. Protective grid
.. DC or AC drive for helix and pad-dle (joint or separate)
For DC-drives, a wide choice of con-trollers is available.
Feed rate and agitation setpoints can be entered via potentiometer, with or without display, for continuous or batch mode. External presetting via analog signal input is also possible.
For optimum adaption of the feed system to the application, beside the basic feeder, a wide choice of feed equipment and accessories is avail-able.
Function
Volumetric AccuRate feeders operate according to the “flexible-wall princi-ple” introduced by Schenck-AccuRate more than 30 years ago.
Instead of the usual internal agitators, all feeders are fitted with two external paddles that gently massage the molded hopper. This ensures a con-tinuous, even flow of material into the helix with a uniform bulk density.
This avoids bridging and material build-up. Additionally, the flexible-wall principle ensures a constantly high filling degree of the helix.
