Recens® Dust Suppression Hopper
Dust suppression hopper that stops dust at source when loading bulk material into trucks or bins. A standing column of material prevents the falling stream entraining air, with no fan, no filter and no power supply required.
Applications
The Recens® Dust Suppression Hopper stops dust being made in the first place. Most dust at a loading point is not caused by the material itself but by the air that the falling stream drags down with it. The hopper works by keeping a standing column of material inside the body: the incoming product falls onto material, not into empty air, so it never gets a chance to entrain air and throw off a dust cloud. The result is a clean loading point with no dust collector, no fan and no power supply — which is why this unit is normally installed under the discharge of a belt conveyor or bucket elevator feeding trucks, rail cars or a silo.
Key Features
• Material-on-material flow keeps a seal column inside the hopper, so the falling product does not generate a dust cloud
• No power, no fan and no filter needed for normal loading duties — nothing to run and almost nothing to maintain
• Fitted with a flexible dust skirt at the outlet that follows the loading height and closes the gap to the truck or bin opening
• Fabricated body with wear liners at the impact zone, so abrasive grain, fertilizer and clinker do not cut through it
• Flange connection to suit the discharge of a belt conveyor, bucket elevator or silo outlet; installation height set to the vehicle being loaded
• Optional level indicator so the operator knows when the vehicle is full and stops the feed
• Optional telescopic version for variable vehicle heights, and an inspection door for cleaning and liner replacement
• Can be supplied with a connection to a central dust extraction system where local regulations ask for it
Applications
Grain terminals and depots — loading wheat, maize, rice and soymeal into trucks
Fertilizer loading bays — urea, NPK and ammonium sulphate
Cement, clinker and fly ash loading points
Chemical and mineral powder transfer stations
Coal and power station bulk loading
Sugar, starch and salt loading
Technical Specifications
Working principle: passive gravity type; material seal column suppresses dust at source
Power supply: none required for the standard passive unit
Handling capacity: sized to the feeding conveyor; typically up to 1,000 t/h depending on material
Inlet: flanged to suit the conveyor, elevator or silo outlet
Outlet: with flexible dust skirt; outlet size matched to the material and loading rate
Construction: welded carbon steel body with wear liners; stainless steel on request
Options: level indicator, telescopic body, inspection door, dust extraction connection
Because the hopper is built around the loading point, the size, the outlet and the height all depend on your vehicle and your conveyor. Send us those details and we will size it for you.
Why Recens
Recens has spent more than two decades building conveying and bulk handling equipment for grain, port, fertilizer and chemical operations. A dust suppression hopper is a simple piece of steel, and it only works when it is sized correctly for the material and the fall height — so we size each one against the actual loading point rather than shipping a standard box.

Overview
Features
Dust is suppressed at source rather than collected afterwards — the hopper holds a standing column of material so the incoming product falls onto material and never entrains air
No power supply, no fan and no filter needed for normal loading duties, so there is nothing to run, no filter to change and almost no maintenance
Flexible dust skirt at the outlet follows the loading height and closes the gap to the truck body or bin opening, keeping the dust inside the hopper
Welded carbon steel body with wear liners at the impact zone, so abrasive grain, fertilizer and clinker do not cut through the structure
Flanged inlet to suit the discharge of a belt conveyor, bucket elevator or silo outlet; installation height set to the vehicles being loaded
Optional level indicator tells the operator when the vehicle is full and the feed can be stopped, avoiding overfilling and spillage
Optional telescopic body for sites that load more than one vehicle height, and an inspection door for cleaning and liner replacement
Can be supplied with a connection to a central dust extraction system where local environmental regulations ask for it
Suitable for free-flowing granular and powdery materials — grain, soymeal, fertilizer, cement, fly ash, coal, sugar, starch and salt
