The Dust Suppression Hopper (DSH) prevents the formation of dust clouds during the transfer of bulk solids.
DSH operating in the exact same environment as the telescopic bellows, demonstrating its performance.
Originally developed to tackle dust emissions at a fertilizer plant, the DSH is now used for a range
of materials including:
• Foodstuffs – salt, sugar
• Minerals and quarry products – bauxite, gravel, kaolin, sands, soda ash
• Grains and stock foods – corn, barley, sorghum, soya beans, wheat
• Fertilisers– superphosphates, lime, potash
This list is far from exhaustive and recent additions include compressed wood pellets and other pelleted products for the biomass industry. In general suitable materials are dry, granular and free flowing, as fine, sticky powders do not perform so well.
The design of the DSH marks a radical departure from conventional telescopic bellows and produces a denser, less aerated flowing material phase.
A conical outer hopper is suspended from the top frame of the unit by a Patented Suspension system. Within the hopper is Patented Device designed to control the flow through the hopper. As material flows into the DSH its weight causes action on the suspension system and the outer hopper lowers relative to the Flow Control Device. The continuous oscillation up and down during discharge maintains the characteristic solid-looking stream of product.
