Our rotary dryers

We offer a standard range of rotary dryers with diameters between 3m and 6m and throughput of  ≤5.0tph to ≥1,000tph in a single dryer. For applications that fall outside of these specifications, we provide custom solutions. Our rotary dryers can operate as stand-alone equipment or can be integrated with other equipment, such as mills, for a complete flowsheet solution.

Frequently asked questions

FAQs for rotary dryers

A rotary dryer is used to reduce moisture content of materials by bringing them into contact with heated gas.

Material is fed into one end of a rotating drum. When inside, material is lifted by internal fins as the drum rotates, and then cascades down through a hot gas steam. This removes excess moisture and delivers a dried final product.

FLS rotary dryers can handle throughputs of more than 1000tph.

FLS rotary dryers fuel options include natural gas, light or heavy fuel oils, coal, petroleum coke, and hydrogen.

FLS rotary dryers can process a wide range of materials, including bauxite, carbon, catalyst, clays, copper concentrate, dolomite, fertilizer, gypsum, iron ore, limestone, lithium carbonate, mineral sands, nickel ore, phosphates, polyhalite, pozzolan, magnetite, sand, soda ash, sodium monohydrate, trona, and zinc.
