Granulate deduster for injection molding and extrusion
HELIO®Clean Pro
Plastic granulate and regrind dedusting before processing
Perfect degree of dedusting
at throughputs of up to 150 kg/h*
by 5-stage dedusting process.
- Control stand with intuitive operator guidance
- Separate sifter for mounting on processing machine or container
- Smallest possible energy consumption
- 2× ioniser integrated
- Air sifting with ION-flushing
- SUPERCLEAN function**
* depending on the material and the required degree of dedusting;
example based on PMMA/PC/COC/COP
** Extra long cleaning of the sifter using ionised air
and optical monitoring of ion generation
Dedusting process
Via the integrated, steppless conveying technology resin/regrind is gently sucked into the dedusting chamber (sifter) in portions of 0.5 to 2.0 liters. These dedusting portions, which are always the same, are passed through the dedusting device several times as material fountain, ionised air flows throuh it several times removing dust in the process. After transfer of the dedusted portion to the downstream process, the special glass sifter is cleaned and a new cycle is started.
5-stage dedusting technology
- Conveying
Pre-dedusting during filling by slow vacuum conveying.
- Loosening
Stepped soft start with loosening.
- Air sifting + ion shower
Gentle air sifting with ionised air. Adjustable fountain with laminar air flow and dust removal.
- Discharge
Transfer of the dedusted portion to the downstream process.
- Cleaning with SUPERCLEAN
Automatic cleaning and neutralization of the sifter glass with optical display between dedusting cycles.
Material fountain
An adjustable, laminar air flow of ionised air carries the material to be dedusted up to the upper third of the sifter.
In the reversal zone the force of gravity outweighs the wind sifting force, the material flows along the glass wall back to the starting point without leaving the open bottom dedusting chamber (sifter). This process is time-controlled, freely adjustable and is repeated several times.
Only when the vacuum is switched off, the dedusted portion falls into the intermediate container below.
Ion shower while air sifting in the material fountain
While the granulate is circulated in the deduster, a continuous stream of ionised air is sucked through the portion to be dedusted.
In this way, the binding forces between dust particles and granules are reduced to such an extent that the dust loosens and can be separated by air sifting.
Due to the special glass construction, the ions are particularly „long-lasting“ and therefore lead to a high efficiency of the ion shower.
Special glass construction
The dedusting sifter is made of abrasion-resistant special glass. This allows efficient cleaning with the aid of ions, as these are not neutralized immediately when they hit the separator wall, but can release the binding forces between dust and material over a longer period of time.
This design also enables the conveying and cleaning process to be viewed from all sides.
Assembly variants
Type-M version for direct mounting on the processing machine.
Example: HELIO®Clean Pro on processing machine
Example A
Conveying from a day container with subsequent dedusting of the material directly on the feeding zone.
Example B
Conveying from an octabin or Big Bag by means of an OKTOMAT® discharge station with subsequent dedusting directly on the feeding zone
Example C
Integration into an existing conveying line by means of the HELIOS dedusting adapter with subsequent dedusting directly on the feeding zone of the processing machine or on a day container.
