Fluid bed dryers save fuel in mortar
production
Ventilex fluid bed dryers from Orthos have been developed to bring improved fuel economy and other operational benefits in sand processing for the expanding dry silo mortar market
Many major companies, including RMC, CPI and Tarmac, are adopting this technique Compared to traditional rotary drum plant, the fluid bed dryer/cooler reduces moisture content and offers large throughputs over relatively small bed areas so that machines can be smaller and less expensive for a given granular mineral drying capacity

New "Ventura" dryer from Ventilex
The Dutch company, Ventilex, known internationally for its high-efficiency, continuous fluid bed dryers, has recently introduced a new version, the Ventura 2-stage drying system
The Ventilex plant dries between 50 and 60 tonnes/hour of sand containing 6 to 15% moisture and achieves a final moisture content of less than 0.5% with a plant exit temperature of approximately 50C.
Efficiency is enhanced by the ability to heat the drying air to 550C and by the plug-flow and sub-fluidisation behaviour generated in the bed of product.
Smaller plant size also allows installation inside a building, away from the effects of changing weather conditions.
Operational versatility is ensured by the ease with which fluidisation and speed of product movement through the plant can be adjusted as required.
Evaporative cooling is another benefit, giving more rapid cooling and removing 1 to 2% of moisture in the cooler.
This means that the dryer can operate at increased capacity, as the target moisture content does not need to be achieved solely in that section. Request a free brochure from Orthos (Engineering) ...
