Key benefits of our flash dryers

Our flash dryers

FLS flash dryers/heaters use gas suspension drying (GSD) technology to various fine materials. Offering throughputs between ≤1.0tph up to ≥750tph, our dryers can operate as stand-alone solutions or as an integrated system with other pyro-equipment, such as rotary kilns, indirectly heated rotary kilns, gas suspension calciners, or multiple heath furnaces, to improve overall efficiency. We can accommodate a wide range of fuels, including hydrogen firing, and can include an optional back mixer to adjust final product moisture.

FAQs for flash dryers and flash heaters

Fine material is introduced above the gas suspension dryer venturi, where it is entrained in hot gases and dries in seconds. A cyclone separates dried particles from the spent gas, which is dedusted in a dust collector. Cyclone and dust collector underflow exit the system as product.

Our flash dryers can handle a wide range of fine materials, such as potash, phosphate, limestone fines, alumina, trona, clays, talc, and other mineral products.

Flash dryers/heaters offer higher thermal efficiency, more compact design, lower maintenance, and greater feed versatility. The rapidity of drying/heating also eliminates overheating, preventing product degradation and maintaining product quality. Flash dryers/heaters are thus a much more cost-effective solution to processing fine materials that alternatives.

Due to its use of gas suspension drying, FLS flash dryers are known for their high energy efficiency.
