🏭 What Machinery Is Essential for Setting Up a Biomass Pellet Plant?
Setting up a biomass pellet plant involves a series of processes to convert raw biomass into uniform, high-density pellets used for fuel, heating, or industrial energy. Below is a detailed breakdown of essential machinery required, along with how PelletIndia, a division of Servoday Plants & Equipments Limited, can support you throughout the journey.
🔧 Essential Machinery for a Biomass Pellet Plant
1. 🌾 Raw Material Handling Equipment
Hydraulic Moving Floor / Belt Conveyor / Screw Conveyor For smooth transportation of raw materials like wood chips, Napier grass, rice husk, etc., to the initial processing units.
Feeding Hopper with Level Sensors Ensures regulated and controlled feeding to prevent blockages.
2. 💧 Dewatering System (For Wet Biomass like Napier Grass)
Napier Grass Press Roll / Squeezer Removes up to 30–35% moisture before drying. Reduces drying energy load.
3. 🔥 Drying System
Flash Dryer or Rotary Dryer Essential to reduce the moisture content of raw material to below 12–15% for pelletizing.
Flash Dryer: Suitable for finely ground material.
Rotary Dryer: Suitable for bulky or fibrous materials.
4. 🔩 Grinding System
Tear Drop Hammer Mill with Pneumatic Vacuum System Converts dried biomass into a uniform powder, increasing surface area for pellet binding.
5. 🧲 Magnetic Separator
Removes iron and metal particles to protect downstream equipment, especially the pellet mill.
6. 🔁 Mixing and Conditioning
Ribbon Mixer Homogenizes the powdered material and prepares it for uniform pelletizing.
Dosing Feeder System Precisely feeds material into the pellet mill, ensuring consistent pellet quality.
7. ⚙️ Pelletizing Unit
Ring Die Pellet Mill (2–5 TPH capacity) The heart of the plant. Compresses material into high-density pellets. Features include:
Gear-driven transmission
Pressurized lubrication
Automatic grease system
8. 🌬️ Cooling System
Counterflow Pellet Cooler Reduces pellet temperature from ~90°C to near ambient, increasing durability and shelf life.
9. 🧹 Screening System
Vibrating Sieve Removes fines and broken pellets, recirculating them for reprocessing.
10. 🏷️ Packaging and Storage
Jumbo Bag Filling Station / Automatic Bagger For bulk packaging.
Silo Storage System For larger storage and feeding into boilers or for transport.
11. 🎛️ Control Panel & Automation
PLC-Based Centralized Control System For automated operations, real-time monitoring, and fault detection. Improves productivity and reduces manpower needs.
