Volumetric Feeder

Volumetric coal feeder is basically a drag-chain en-masse conveyer with an externally adjustable bed height controller. The cross-section area at the bed height controller and the speed of the bed of material gives the volumetric measurement of the coal. The variation in coal flow is achieved by either adjusting the coal bed or varying the chain speed using variable frequency drive.These feeders always have a horizontal profile with capacities upto 120 TH and lengths of even 25 meters.The other construction is similar to Chain Feeders with additional safety features as per the requirements of customer. The chains used by DEMECH are Drop forged chains, with single strand or double strand construction as per the capacity requirements.
