Circular Pelletizing

Circular Pelletizing Technology - The next step in efficiency

A new standard for a new flexibility: ultra-compact pelletizing plants from Primetals Technologies stand for maximum flexibility, excellent pellets quality, high energy efficiency as well as low overall investment cost.

Circular Pelletizing Technology from Primetals Technologies is the next step in the evolution of highly efficient, ultra-compact pelletizing plants. It is smaller by half than conventional plants and offers completely new flexibility in integration and pellet production. It frees you from rising costs for pellet supply – with the world‘s most compact pelletizing plant.


​Plant Special Features​

Based on more than 40 years of experience in straight grate pelletizing, Primetals Technologies has combined the best of two worlds – the well-proven travelling grate process with the simple and robust mechanical design of a circular dip rail cooler. The result is a revolutionary technology which reduces the size of a typical pelletizing plant by half: the Primetals Technologies Circular Pelletizing Technology – the world’s most compact plant for pelletizing by far thanks to a low building profile, short process air ducts and completely standardized equipment - is a milestone in the cost-minimized iron production with in-house made pellets.

​Compact design, easily and cost-efficiently integrated

The complete plant is as small as a sinter cooler and can be integrated easily and cost-efficiently within existing steelworks, even in sites where almost no free space is available. In comparison with conventional plants which are built up on a massive construction, the Circular Pelletizing Technology from Primetals Technologies stands out through its ultra-light design and offers maximum flexibility to define the plant location. Our innovative pelletizing technology stands for excellent pellets quality as produced in straight grade induration machines and at the same time high energy efficiency due to intelligent re-use of hot gas. Reduced costs, easy handling and transportation, optimized chemical properties: Experience the new freedom in pelletizing – with Circular Pelletizing Technology.

CPT - The Circle of Flexibility

Circular Pelletizing Technology (CPT) is the world's most compact pellet plant. Thanks to the circular design of the induration furnace, low building profile and small overall footprint, the plant can be easily and cost-efficiently integrated in existing steelworks or mining sites. The process is based on proven travelling-grate pelletizing technology. The output of CPT can be high-quality blast furnace or direct-reduction pellets. The plant is available with pellet production capacities from 800,000 t/a up to 2.5 million t/a.

Main benefits

  • Circular plant design and low, light-weight building structure for low capital expenditures
  • Highly efficient utilization of circular-grate equipment – only 25% of pallet cars not inside the induration furnace
  • 100% recycling loops of all input materials for minimum environmental impact
  • Intelligent re-use of hot process gases for a major reduction in the overall energy consumption
