Circular Pelletizing Technology


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.
