Granulate deduster for injection moulding
HELIO®Clean Pro

Plastic granulate and regrind dedusting before processing

HELIO®Clean Pro 10

Granulate cleaning before processing in plastic injection moulding

The new HELIO®Clean Pro 10 conveying and dedusting device was specially developed for injection moulding and is characterised by particularly gentle conveying and dedusting with an ion shower.

An integrated conveyor system sucks resin/regrind into the dedusting chamber and gently dedusted by means of air-floating with an ion shower.

  • maximum dedusting degree
  • gentle dedusting
  • control stand with cleaning aid
  • compact or split construction
  • 1- or 2-component version
  • air- floating with ion-cleaning
  • 2x ionizer integrated
  • 4-stage dedusting process
  • material throughput up to 35 kg/h*

Dedusting technology

Perfect granulate cleaning with the HELIO®Clean Pro dedusting technology

An integrated conveyor system sucks resin/regrind into the dedusting chamber. The conveying speed can be preselected steplessly and new dust formation due to abrasion can be avoided. A portion of exactly the same amount is gently dedusted by means of air-floating with an ion shower. The resin/regrind is sucked only as high that it does not touch the sieve disc at the dust outlet or leave the separator when the sieve disc is removed. Light parts such as dust or lint leave the separator at the top through the sieve disc and are separated into the dust collection container. HELIO®Clean Pro - devices without a sieve disc are even able to remove angel hair safely, which is produced when conveying plastic granulate.

4-stage dedusting technology


Conveying

Pre-dedusting during filling by slow vacuum conveying.

Loosening

Staged soft start with loosening.

Air floating + ion shower

Gentle air- floating with ionizedair. Adjustable Fountain with laminar air flow and dust removal.

Cleaning

Automatic cleaning and neutralization of the separator glass by ionized air betweentwo dedusting cycles and dust removal.

 

 

Material fountain

A laminar air stream with ionized air carries the material to be dedusted adjustable up to the upper third of the separator, where it reverses by gravity and returns to the starting point at the glass wall without leaving the open dedusting chamber (separator) at the bottom. This process is time-controlled, freely adjustable and repeats itself several times. Only after switching off the vacuum the dedusted portion is transferred to the intermediate container below.

Ion shower

While the granulate is whirled up and circulated in the deduster, a continuous stream of ionized air is blown 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-floating. 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 chamber 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 versions Pro 10

Split construction type-b

Split construction for mounting on drying container

Conveying and dedusting of the material on drying containers with following drying. The valve box can be easily disassembled and attached to the desired position, e.g. hooked up to the container handle.

Compact version type-m

Compact version for mounting on processing machine

Conveying and dedusting of the material directly on the feeding zone.

HELIO®Clean Pro 20

Granulate cleaning before processing in plastic injection moulding

The new HELIO®Clean Pro 20 is the most powerful HELIOS conveying and dedusting unit and was specially developed for injection moulding. It is characterized by particularly gentle conveying and dedusting with an ion shower and is suitable for the most difficult dedusting tasks.

  • high material throughput
  • gentle dedusting
  • control stand with cleaning aid
  • special glass construction
  • or 2-component version
  • air- floating with ion-cleaning
  • 2x ionizer integrated

Practical example: HELIO®CLEAN Pro 20 deduster on processing machine

 

Version A

Conveying and dedusting of the material directly on the feeding zone.

Version B

Material drying via stand alone dryer with subsequent conveying and dedusting of the material on the feeding zone.

Control stand with dust collecting container - Pro 10 / 20

Equipment

  • 5-stage vacuum generator
  • dust collecting container
  • automatic filter cleaning
  • integrated cleaning aid
  • system pressure regulator
  • quick coupling for control line

Operation

The basic setting and the possible settings for the four functional areas are visible at the control stand. Each function key has several sub-levels which can be called up by pressing the key. Detailed operating instructions allow you to optimize the process steps for each application.

Dust collecting container

The dust collection container can be simply pulled out and emptied.

Integrated cleaning aid - easy handling - Pro 10 / 20

Use as cleaning aid

To clean the dust extractor, the control stand can be used as a classic vacuum cleaner. Instead of the dust discharge hose, the vacuum cleaner hose is plugged on and used together with one of the supplied cleaning attachments.

The dedusting chamber can be hinged down / swivelled out

The dedusting chamber can be hinged down for cleaning (Pro 10) / The upper part of the deduster can be released and swivelled out (Pro 20).
