The MRS® (Magaldi Mill Rejects System) is a new process concept designed to mechanically handle rejects from coal mills, in a dry way. Rejects are a mixture of different materials (pyrites, stones, tramp iron, etc.) with pulverized coal, requiring a reliable and safe removal system.
The situation is further complicated by the ‘mill reject’ streams that reject undesirable material (tramp metal and non-coal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •
