layout design for a coal-biomass pellet production facility. This layout is optimized for a production capacity of 4–5 TPH, with coal and biomass as the raw materials.

Key Sections in the Layout

1. Raw Material Handling
   • Coal Storage Hopper: For storing crushed coal.
   • Biomass Storage Hopper: For storing shredded biomass.
   • Feed Conveyors: SS/MS conveyors to transport raw materials to the mixer.
2. Crushing & Shredding
   • Hammer Mill (Coal Crusher): Pulverizes coal to <1mm particle size.
   • Shredder (Biomass): Reduces biomass to <3mm particle size.
3. Drying
   • Rotary Drum Dryer:
     • Input: Moisture up to 25%.
     • Output: Moisture reduced to 8–12%.
     • Heat Source: Biomass, gas, or coal combustion.
   • Includes a hot air generator and exhaust ducting.
4. Mixing
   • Ribbon/Paddle Mixer: For homogenizing coal and biomass in desired ratios (e.g., 70:30).
   • Positioned after drying for a consistent mix.
5. Pelletizing
   • Pellet Mill:
     • Ring die with a 4mm die size.
     • Capacity: 4–5 TPH.
   • Located centrally for easy access to raw material inputs.
6. Cooling
   • Counterflow Cooler:
     • Cools pellets to near ambient temperature.
     • Positioned directly after the pellet mill.
7. Screening
   • Rotary or Vibratory Screener:
     • Removes fines and broken pellets.
     • Returns fines to the mixer for reprocessing.
8. Finished Product Handling
   • Storage Silos: For finished pellets.
   • Bagging Section: Optional, for packaging pellets in bags (50 kg or jumbo bags).
9. Utilities & Ancillary Sections
   • Control Room: For monitoring operations.
   • Dust Collection System: Cyclones or bag filters at crusher, dryer, and pellet mill.
   • Power Supply Unit: Includes transformers and switchgear.
   • Workshop Area: For maintenance and repair.

Proposed Layout Design

Here’s a conceptual flow:

1. Input Section:
   • Coal hopper → Coal crusher → Dried coal storage.
   • Biomass hopper → Shredder → Dried biomass storage.
2. Processing Section:
   • Dried coal + biomass → Mixer → Pellet Mill.
3. Output Section:
   • Pellet mill → Cooler → Screener → Storage silo → Bagging.
