Chain Bucket Unloader for Coal Fired Power Plant

Chain bucket unloader applied to coal-fired power plant  1. generalThe chain bucket unloader is specifically designed to unload bulk material from a railroad car. It`s mainly used to unload bulk materials like limestone, coal, and wood pellets. The portal Chain Bucket Unloader is crossed over the wagon and unloads the coal by means of chain bucket drawing and belt conveyor conveying coal outward. Its advantages are no need to open the door of the wagon and has high work efficiency and good economic benefits; It can unload coal several meters away from the track, which is conducive to continuous unloading; The traveling speed and conveying capacity are relatively stable, which is convenient for joint operation with other machinery to complete the conveying and stacking task at one time. 2. Specification of chain bucket limestone unloaderWork duty:3 shift heavy-duty,365days per yearUnloading capacity: 100t/hRail distance: 6000mmPower supply: cable reel(power), less than 200Power: 380-400VFrequency: 50HzUnloading rate: ≥95%Consumption power: 100KW3.
