  4. 4. For removing tramp iron piecesLocation - discharge of Conv. 42A/B, 31A/BEfficient cost-saving recovery of harmfultramp iron in free-flowing materialsThey are simple to install and have nomaintenanceInstalled over conveyor . .
  5. 5. To detect non-magnetic metallic materials presentLocation - 32A/B head, 38 A/B
  6. 6. Removing left tramp iron piecesLocation - discharge of 32A/B in crusher – to remove any tramp iron piece present in coal before entering crusher - TP 21 – to avoid entry of the same in bunker - TP 27 – to eliminate the same from the coal coming from stockyardInstalled at discharge of conveyors near pulleyILMS includes belt, pulleys, magnet etc.

EQUIPMENTS FUNCTIONS Conveyors Auto /manual operation of gates/ Dust suppression system valves/ dampers, pumps, drives, Paddle feeders Local / remote selection of Mobile trippers over bunkers operation, Belt weighers Status indication, annunciation, interlo Metal Detectors ck and protection of pumps/drives Inline Magnetic separators Suspended Magnets Coal sampling Units Hydraulic scoop Coupling
  13. 13. It consists of a series of overlapping Heavy Duty Pans (or Flights) thatcarry the material.Used for handling more abrasive, heavy and lumpy material. Thematerial is carried on an overlapping metal plate called pans, which ismounted between strands of the conveyor chain.Apron feeders are placed under storage bin for regulating the feedmaterial
  14. 14. An Apron Feeder can regulate the flow of material based onvolume. The pan speed and the gate cut off height can be regulated toprovide an even volumetric feed down stream. .
  15. 15. A short belt conveyor. The belt is flat and supported on closely spacedidlers or on a smooth slide plate.Belt feeders are used for handling fine / free flowing / abrasivematerials. Even properly designed belt feeders are used for handlinglumpy material.Increased redundancy and flexibility
  16. 16. Used when only one outlet is used to feed two different belts2 in no. in stage 3Location - Crusher house
