The GEA Potash Conditioning System features a condition drum and fluid bed for glazing , polishing and drying of granular Potash which significantly improves product quality and operating efficiency. The lifters, drum angle, spray pattern, rotation speed and residence time can be adjusted meet the required product specification.
Significantly improving Potash quality and process efficiency.
The product potash feed from the client's upstream process is introduced to the conditioning drum at a continuous and stable feed rate with consistent moisture content and temperature. As the particles travel through the drum, spray water nozzles glaze and condition the potash with a fine misting of water for uniform product coating, while the drum promotes rapid product tumbling for optimal polishing.
The wetted product is subsequently discharged directly into a fluid bed dryer via a discharge chute. The material is distributed across a sloped directional fluidizing bed plate which propels the material towards the discharge end of the fluid bed. The plate is dimensioned to provide plug flow, allowing an optimal degree of fluidization while upward airflow prevents material from falling through to the lower plenum. An adjustable underflow discharge gate valve controls the material bed depth which varies the retention time and enables rapid and complete emptying of the unit.
Process fluidization air is supplied by a forced draft fan and exhaust gases are passed through a baghouse for dust collection before discharge to atmosphere via an exhaust fan. Slightly sub-atmospheric conditions are maintained above the bed by means of a balanced system of forced and induced draught fans which eliminate the need for air seals at the feed and discharge points.
GEA Static Fluid Beds are widely used throughout the process industries for drying, cooling and calcining of powders, crystals and granules.
The GEA Rotary Dryer is extensively used throughout the process industries and is highly reliable under the most arduous operating conditions.
