After the relocation of a grinding room orthopaedic technology, RUWAC provided an updated individual extraction solution over the previous central system for highly reactive titanium dust.
An orthopaedic technology company were relocating their grinding/ polishing room. With the extraction of titanium dust, an Atex-rated solution is required. The room previously used a centralised vacuum system with a wet separator, however with the new room location on site, there is a large concern around the distance the material will have to travel within the thepipeline, Titanium dust is highly reactive plus it has large ignition risk whilst in the pipeline.
RUWAC’s approach for the company was to introduce individual wet separators placed directly to the grinding machines and the drives, this was achieved by means of piping to the outside in an air-conditioned container. The solution was a RUWAC NA 250 type III-S-RF-D with drive unit Zone 22, identified according to AtexII3D, housing anti-static throughout made of glass fibre reinforced polyester, no friction and impact sparks.
The systems run at approximately 110mbar, which means approximately 570m³/h according to the current characteristic curve. (However, for grinding machines it could be more.)
The system has a remote control with overrun and level monitoring (minimum). If the level is too low, the system switches off and the fault is indicated by a red signal light. The fault must be acknowledged at the control cabinet before the system can be put back into operation. providing high safety levels.
The drives are equipped with 100% exhaust air and were connected to a pipe to the outside (however, quite loud in the blow-out area). For safety reasons, the drives were additionally provided with residual dust filters.
