Abstract— Scraper Assembly is a prime component of a coal mill, which is considered as the reject handling component, to take out the ungrinded material from the mill which gets collected in the pyrite box.
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.
unit came with a special headbox and modified spray system to handle a sludge flow of 700 GPM with 1% to 2% solids. Results The Rotoshear® screen with " openings solved the problem and the irrigation system worked fine. No more nuisance clogging! In 1989, when production levels reached 1,400 tons per day, the mill expanded again.
Removed periodically. Any material having. a bulk density tonnes/m3 should be. rejected (for coal it is tonnes/m3). However sometimes the material to be. ground is also rejected. Farakka. Introduction. Each mill has one Inlet one Outlet Reject.
