A tertiary crusher in a cement plant is a high-efficiency crushing machine that further reduces the size of raw materials after they have been processed by primary and secondary crushers. This crusher uses mostly impact, cone, or roll crushing methods to produce fine and consistent product sizes. Tertiary crushers are essential for ensuring the material is appropriately fine enough for the next phase of the production process, where it’s ground into cement. They help improve the efficiency and throughput of the entire cement production line.
