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.
All kind of powders, crystals, beads, granules, fibers, cakes, chips, for all industries (chemical, food, mineral, etc.).
Drying, cooling, calcining, reaction, reduction, dehydration, solvent removal, granulation, coating, polishing, shake-out, etc.
PILOT TEST LABORATORY:
For determination of rotary tube parameters and possibility to perform semi-industrial tests.
