Refined and Robust Control

The dust suppression hopper is simply installed as a loading spout under a feed point. It’s suspended above the target area to reduce dust while transferring dry, granular, free flowing materials. Designed for the loading of ships, trucks, trains, silos and storage containers or bags; it effectively reduces dust hazards, health risks, wastage, cleaning and maintenance. Due to the dust being held within the main material column it also increases the overall storage capacity & saleable material yield. The standard version of the dust suppression hopper requires no power at all, has no internal moving parts and when you need to manage the load-out of a range of different materials from the same conveying system, the more advanced positional feed control model is available. This dust control model includes a built in computerised control to manage the discharge rate for products with different specific gravities. The combination of the surface tension, compression of the material and the vortex generated from the drop means dust is trapped inside the column regardless of the height of the fall leaving a tidy flow that concentrates the output.

The above load-out rates are guidelines only. The hoppers can be configured to suit your requirements depending on the specific gravities of the product being loaded.

You can specify the construction material of each dust control product to suit your requirements. These hoppers are produced in Polyethylene rotational moulded hoppers which cover most applications. They can also be constructed in Steel. 304 stainless steel hoppers can be used for warm or abrasive products or 316 stainless steel hoppers for food grade and corrosive situations. Steel examples are Electro Galvanised, Mild Steel, Corten and Hardox.

The Dust Suppression Hoppers are produced in two models that can be any size or construction material. The standard model requires no utilities and has no internal moving parts. The position feed control model has a computerised discharge rate control system for products with different specific gravities; thus allowing the load-out of various materials on the same conveyor system. All DSH System Ltd models can be configured for position feed control configuration.

In summary

The Dust Suppression Hopper offers you less waste and maintenance with low operating costs. It’s easy to install in a variety of sizes to meet your capacity and material needs and increases your product yield through concentrating and minimising dust. All this for a moderate investment giving you an excellent return.
