Basic pyro processing

Metso Pyro has a complete line of pyro processing equipment that can be custom designed for special applications. The development of new products and the improvement of existing products and processes are Metso Pyro’s goal.  To achieve this goal, Metso operates the Pyro Research & Test Center (PRTC). The Pyro Research & Test Center is a fully-equipped facility with the capabilities to perform complex material and process testing and evaluations and simulate a complete pilot flow sheet. The Test Center is unique in its ability to generate a complete flow sheet with many different unit operations, which can be assembled to represent a commercial plant. In addition, Metso Minerals process engineers are involved in the test work from batch feasibility studies and interpretation of pilot plant results to commercial equipment sizing, design, supply, installation and start-up.
