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.

Intelligent process optimization for pelletizing plants
The ultimate aim in pelletizing is to produce consistently high pellet quality at high productivity rates and low conversion costs—while at the same time fulfilling the emission limits imposed on operation. Owing to the mutual interdependence of the different pelletizing process steps, precise simulation is essential to reliable process optimization.
Different shift operators tend to operate the machine in different ways. Equalizing to optimized operational decisions over all shifts will lead to maximum production of quality pellets at minimal production costs.
Primetals Technologies has developed an Expert System for pelletizing plants, which is supported by advanced process models that provide additional insight into the process and support operational decisions. The pellets on the surface, the bottom, the walls, and the center face different process conditions, so the process models predict, evaluate, and track these conditions on a fine-meshed grid in all cross sections throughout the whole process chain. Extended simulation capabilities support the identification of optimal operational points—in order, for example, to optimize the trade-off between the energy supply to the different process steps in the drying and induration zones.
- High productivity and reduced energy consumption – Pelletizing plant is running at peak performance while minimizing consumption of fuel gas and electrical energy for waste gas fans
- Product quality - Chemical and physical properties of the sinter product maintained at the desired levels
- Stable and shift-independent operation - Best-practice pelletizing plant operation 24 hours a day to ensure efficient production
- Return on investment - The standard period is expected to be less than one year
