De-dusters

De-dusting is used to prepare foam materials from granulation/grinding - to ensure that it was possible to mix with new beads before the moulding process.

KBM has supplied these solutions since 1978 and has developed different equipment to refine this process ever since to obtain the optimal de-dusting quality.

Today, it is often necessary to de-dust in other locations in the moulding process. The raw material (virgin beads) is often full of small particles and fine dust, and it is very important that these particles are removed before the moulding process.

Why you should be de-dusting

De-dusting must be done to:

• Increase the quality of the moulded pieces (shape moulded or block moulded)
• Avoid production stops caused by dust sticking to the moulds and with a lot of maintenance work as the result.
• Increase the rate of recycled material that can be added and re-used.
  
  

KBM has for many years been manufacturing the MINI, MAXI, and JUMBO recycling systems with vacuum dedusters. These products have capacities like 10 m3/h, 18-20 m3/h, and 35-40 m3/h. Lately a larger version JUMBO+ was developed to give 50-60 m3/h. This unit has now been developed further into the GIANT 120 and GIANT 240 with capacities of 100-120 m3/h and 200-240 m3/h for the large block moulds.

With the variety in capacity from 10 m3/h up to 240 m3/h KBM is able to supply for all purposes of de-dusting: recycled or virgin - or after it is mixed.

To keep the quality and efficiency high and maintenance of the de-dusting systems on a minimum, KBM has developed a cyclone venting system for the extracted dust. The cyclone removes the dust form the de-dusting air. The collected dust is compacted to avoid large volumes of waste. The air is returned in a “closed loop” and reused in the system instead of venting it through filter bags which require a lot of maintenance.
