Mobile grinding-dust extraction directly at the source
Depending on the material, grinding produces coarse particles, fine dust, and, in some cases, sparks. Mobile systems offer a flexible solution when workstations change or no central extraction system is available. Extraction should take place as close as possible to the tool or workpiece.
Key Selection Criteria
✔ Material and dust type
✔ coarse and fine particle fractions
✔ potential spark generation
✔ Tool connection, hood, or extraction arm
✔ Hose length and diameter
✔ Filter cleaning and dust collection
✔ ATEX requirements, if applicable
On-tool extraction or extraction arm?
Tool-integrated extraction captures dust very close to the source and often operates with a smaller cross-sectional area and higher vacuum pressure. Extraction arms and hoods are more flexible when working with different workpieces and typically require a higher flow rate.
Sparks and coarse particles
Metallic grinding processes can generate incandescent or abrasive particles. Pre-separators or other protective measures can reduce the load on the main filter stage. In the case of combustible dusts, the entire system must be evaluated based on a risk assessment.
FAQ
Can a portable unit handle any abrasive blasting application?
No. The amount of dust, the tool, the material, and the required air flow must be compatible.
Is on-tool extraction better than an extraction arm?
When technically feasible, direct tool attachment is often particularly efficient; an extraction arm is more versatile for this purpose.
When is a pre-separator recommended?
For large volumes of coarse particles or to relieve the main filter stage.
Is ATEX always required for metal dust?
This is not a blanket rule. The specific risk assessment is decisive.
Advice on Grinding Dust Extraction
Material, tool, dust volume, hose length, and desired extraction method are the most important input parameters.
