Recycling

Since the 1950s, COMESSA has specialized in the design, manufacturing, erection and commissioning of a wide range of equipment for drying, calcining and cooling adapted to the requirements of its customers, in environment and recycling fields.

More stringent requirements in terms of respect for the environment have resulted in COMESSA developing and supplying a number of plants for processing of recycled products and waste.

Services we provide range from supplying individual equipment to complete plants, including:

  • Air preparation assemblies (filtration, ventilation, heating systems, exhaust gases recycling from drying operation…)
  • Dedusting assemblies (cyclones, scrubbers, bag filters or post-combustion)
  • Ancillaries equipment (electrical panels, automation, conveyors, etc.)
  • Field supervision services (supervision of erection, start up, performance tests, etc.)

Depending on the product to be treated, COMESSA offers a number of  solutions:

  • Rotary tube dryers, directly or indirectly heated to minimise gas volumes
  • Indirect rotary kilns for calcining in a specific controlled atmosphere
  • Static fluid beds
  • Vibrating fluid beds
  • High temperature fluid beds (up to 950 °C)

Choosing the most appropriate equipment depends on the nature and type of product to be processed.
To validate solutions, COMESSA has a its own test laboratory in which all the technologies can be tested.
