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 main MRS® conveyor, collecting the rejects produced by all coal mills. The MRS® system is designed to easily accommodate any increase in rejects and coal rate.
Unlike conventional systems (hydraulic, pneumatic, or closed mechanical conveying systems), responsible for fire/explosion risks, low dependability due to chain damages or plugging, and premature wear, the MRS® system delivers a reliable, continuous operation, avoiding production losses and heavy maintenance and replacement costs.
