Rotary drum dryer

spiral

Rotary tube is composed of one slightly sloped shell, fitted with two riding rings supported by four rollers and driven by a chain drive or a girth gear assembly. Internal spiral flights and lifters allow conveying of product from the inlet to the outlet of the shell and insure a proper and efficient thermal exchange between product and process gas. Rotary tubes can be used in various configurations : co-current, counter current, indirectly heated through the shell or by means of internal tubular exchanger. They are dedicated to a large range of divided solids from fine powders to large particles. ADVANTAGES OF THIS TECHNOLOGY Handling of heterogeneous products with a large range of shape size and density Proven technology Heavy duty High drying / calcining temperature High flexibility High evaporation Large capacity MAIN APPLICATIONS All kind of powders, crystals, beads, granules, f ibers, cakes, chips, for all industries (chemical, food, mineral, etc.) MAIN PROCESSES Drying, cooling, calcining, reaction, reduction, dehydration, solvant removal, granulation, coating, polishing, shake-out, etc. PILOT TEST LABORATORY For determination of rotary tube parameters and possibility to perform semi industrial tests.
