Dust Suppression Systems for Industrial Production Lines

Fogging a vegetable packing line

A MicronFog™ dust suppression system quickly suppresses dust at transfer points between conveyors and other machinery. These areas are a common source of airborne dust, which arises as material drops from one belt to another or into the inlet point of processing machinery.

By suppressing dust at these points, this system will keep the work area, workforce and machinery clean and the air dust-free.

Dust can be controlled by fitting a small number of nozzles close to the point where dust is generated. By capturing dust at its source and keeping it in the process, a MicronFog™ dust suppression system minimises the need for general dust suppression in the building or expensive dust collectors or extractors.

Nozzles can be fitted in chutes, and open transfer points can be fogged, but will require an increased amount of fog.

Example Applications : Trommels, Open Conveyors and Chutes

Fogging a TrommelTrommel Screens

Trommels are often used to screen waste and other bulky materials , while breaking it up, and transferring it onto another part of the process. This is an obvious application for MicronFog™.

Fog is Fitted to the inlet and outlet of the trommel, keeping dust in this area


Fogging Transfer Points to Control DustConveyor transfer points

Open conveyors transporting dry materials, such as these potatoes , are prone to generating dust, especially as material transfers from one conveyor to another or from one conveying method to another.

Fogging a conveyor line at the transfer points suppresses the dust immediately. In this application, there was no further need for dust suppression in the packing line.

Chute transfer points

Chute with Fog nozzles

Dust is generated as material falls from a conveyor into a chute.

Two fogging nozzles were fitted into the transfer chute without damaging the integrity of the chute. The dust problem was solved.

Demonstration Video – Transfer Point Fogging

This video demonstrates fogging being used effectively at transfer points.

Even very small height differences can allow dust to be generated. Positioning nozzles by the transfer point itself, allows the fog to prevent the dust becoming airborne.

If this is the only area where dust is being generated, a few nozzles could easily solve the dust problems.

Would it wet the product?

Most of the fog which does not combine with the dust will flash evaporate as the droplets are so small. All of the customers we have supplied previously where the product is highly sensitive to moisture have been entirely satisfied that the fog does not wet the product or the production area floor.

Fundamentally, it is all about droplet size, experience and skilled system design.  That is why it simply has to be a Renby system as we have the skill and experience to make it work for your process.
