Rejects discharged from coal mills are a mixture of different materials (iron pyrites, rocks, tramp metal, etc.) with pulverized coal. Magaldi engineered the MRS ® system to ensure their dry removal and mechanical transport from coal pulverizing mills to bunkers, safely and reliably.. Temporarily stored in pyrite boxes, coal mill rejects are extracted by MRS ® extractors and dosed onto the ...
