Large-Scale Plant for Drying and Processing Plastic Pellets

A large processing and drying plant supplied by VIBRA SCHULTHEIS was successfully commissioned at an international manufacturer’s facility.

At the heart of this plant are four vibrating and static fluid-bed dryers. Each dryer is assigned to a different production line and rated for a maximum product throughput of 8000 kg per hour of plastic pellets. The fluidizing plate areas, between 2 and 8 square meters in size, are adapted to the production quantities of the various plastic qualities. Special silos are installed downstream of the fluid-bed dryers for the long-term product treatment that is also required.

The plant has several outstanding features:

• High flexibility enables fluctuations in production to be cushioned
• Optimal energy efficiency due to the circulating gas system and insulated dryer design
• Easy operation and maintenance
  

The scope of supply for the drying plant included the complete air handling equipment for air conditioning and dust removal as well as all instrumentation and control technology, the pneumatic conveyors and the silos.
