ROTARY TUBES


PRINCIPLE

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
