iBulk Solutions, together with their subcontractor Hurll Nu-Way is providing energy efficient solutions for sand drying applications.
Sand quarrying companies looking to increase their sand drying capacities often considered investing in a bigger rotary dryer or a fluidised bed dryer.
While rotary dryers can be a cheaper option but more energy-intensive, fluidised bed drying promises a smaller footprint and considerably lower energy consumption. Fluidised bed technology increases the drying surface of the sand by suspending it in heated pressurised gas, helping to achieve significant energy savings.
Quite often, huge amounts of silica need to be dried, with the equipment handling several tons of material per hour.
iBulk has designed a dryer that can operate with huge quantities of sand. iBulk’s standard product, the Vibrating Fluid Bed System for Drying and Cooling, can be modified to suit the customer’s specifications.
For one of their dryers, iBulk needed a 2.7kW gas burner to heat the system. Hurll Nu-Way offered to supply an industrial in-duct burner manufactured by Nu-Way (UK). With Nu-Way product range offering capacities up to 45 MW, the EnergyStream burner head was selected and delivered to Australia. Combustion specialists and technicians from Hurll Nu-Way designed the duct and incorporated the burner into a compact duct package, complete with a gas valve train and a burner management panel, also designed at Hurll.
The average efficiency of fluid bed dryers is 20-40% higher than rotary dryers, which ensures that iBulk's clients achieve considerable savings on the fuel consumption required in the drying process.
