air filter / gravity / dust
AKW Apparate + Verfahren GmbH
In a world of limited water resources and rising costs to meet environmental requirements, the demand for new technologies to reduce outlay on the separation processes is increasing.
The two major problems facing the industry are:
• limited water availability in arid areas
• environmental restrictions of both water supply and disposal of slurries
In response to this, AKW A+V developed a new kind of dry gravity separator for fines. The recent breakthrough arose from the air fluidised bed, in combination with a specially developed sifter. Latest trials have confirmed its outstanding efficiency.
The optimum working range is for grains less than 3mm. Trials have also shown good results are achievable with differences in density less than 0.3 g/cm3, e.g. feldspar and quartz. Capacities between 5–25 t/h can be attained with units of 1,200 mm width.
