A full range of custom-built technologies

For more than 100 years, COMESSA has developed a wide range of technologies, including all kinds of fluidized beds, rotary tubes, band dryers, flash dryers, rapid dryers.
With its full range of equipment and solutions, COMESSA is able to meet all your requirements in thermal processing of divided solids (powders, crystals, beads, granules, pellets, etc.).

Fluidized beds

Fluidization confers to a divided solid the properties of a fluid. This technology is particularly suitable for products with a narrow particle size distribution.

Rotary tubes

This technology can handle heterogeneous products with a large range of shapes, sizes and densities.

High temperature
(up to 950 °C)

This equipment enables processing of divided solids by indirect heating and can be operated under controlled atmosphere.

Band dryers

It is the most appropriate equipment for fragile, sticky, pasty products or products requiring long and accurate residence time.

Flash dryers
Rapid dryers

Flash drying works on the principle of pneumatic transport using hot air. This process is particularly suitable for fine products or filter cakes.

Double shaft paddle
granulators

This equipment is used for
pre-granulation of fertilizers.
