Silicone caps offer an ideal solution to contain dust during processing. The Hanningfield Uni-Cap is a flexible silicone rubber seal which provides a cost-effective method of the dust-tight transfer or containment of powders.
We’ve outlined some typical applications below, but this really only scratches the surface on the uses of this versatile piece of equipment.
Dust-Tight Milling
Commonly when milling, there will be a receiving drum placed on the outlet of the mill to capture all of the milled product. Rarely will any product not create some amount of dust during the milling process, and without a hermetic connection between the outlet and the receiving drum, the product dust will simply escape into the process room. Using a Hanningfield Uni-Cap can provide a solution to this problem, whereby a Uni-Cap is fitted to the drum lid, and the outlet of the mill pierces through a specified size hole cut into the cap. This creates a quick and easy method of containing dust. Hanningfield can supply a bespoke design lid, including mounting flange for the Uni-Cap, and also breather arrangement to prevent over-pressure within the receiving drum.

Dust-Tight Vacuum Transfer
When using vacuum transfer as a method of transporting material from A to B, the Uni-Vac will always mount above a receiving vessel which receives the sucked powder. Similarly to milling, when the Uni-Vac discharges powder into the receiving container, there is a creation of dust which again can emit into the process room. This can be particularly problematic should the material be hazardous to operators. By using a Uni-Cap on the receiving container, when the Uni-Vac discharges the powder is contained within the drum, with the breather sock preventing over-pressure from the sudden displacement of air from the mass of discharged powder.
Dust-Tight Containers
The Uni-Cap can also act simply as a reliable, FDA compliant and cheap solution to keeping product contained. The Uni-Cap proves particularly useful to safely contain powders during transportation of drums and containers etc.
