Through a scientific process flow and specialized equipment configuration, various biomass raw materials such as sawdust, straw, and rice husks can be converted into high-density, high-calorific-value, and easily stored and transported clean energy pellets.

  • Technological procedure: Raw Material Collection → Raw Material Screening → Crushing → Drying → Mixing → Granulation → Cooling → Screening → Conveying → Packaging
  • Equipment needed process: Raw Material Storage Silo → Vibrating Screener → Hammer Mill Crusher → Rotary Dryer → Mixer → Biomass Pellets Making Machine → Counter-flow Cooler → Vibrating Screen → Screw Conveyor & Bucket Elevator → Automatic Packing Machine
Raw Material Collection

01

Raw Material Collection

Collect various biomass raw materials, including sawdust, wood chips, bark, straw, rice husks, peanut shells, corn cobs, and other agricultural and forestry waste, and perform preliminary classification and quality inspection.

Raw Material Screening

02

Raw Material Screening

Perform preliminary screening and cleaning of the collected raw materials, removing oversized materials, stones, soil, metal foreign objects, and other impurities to ensure uniform material size.

Crushing Process

03

Crushing Process

Crush the screened raw materials to a suitable pelleting size (usually 3-5mm). For wood materials, use a wood chipper and hammer mill; for straw materials, use a straw crusher.

Drying Process

04

Drying Process

Dry the raw materials to the optimal moisture content for pelleting. Excess moisture is quickly removed using hot air to ensure effective pelleting.

Mixing Process

05

Mixing Process

Mix the different raw materials evenly. If necessary, adjust the moisture and temperature using a conditioner to create ideal conditions for pelleting.

Pelletizing Process

06

Pelletizing Process

The core process. The conditioned material is extruded under high pressure in a pelletizer to form dense cylindrical pellets, typically 6-12mm in diameter and 15-30mm in length.

Cooling Process

07

Cooling Process

The pellets exiting the pellet mill are 80-90℃ hot and must be rapidly cooled to room temperature to harden and set.

Screening Process

08

Screening Process

The cooled pellets are graded and screened to remove oversized, undersized, broken, or powdery particles, ensuring consistent finished product quality.

Conveying Process

09

Conveying Process

Materials are efficiently conveyed between the various equipment. Powdered materials are conveyed using screw conveyors, while granular materials are conveyed using bucket elevators and belt conveyors.

Packing Process

10

Packing Process

Qualified biomass pellets are weighed according to standard specifications using an automatic packaging scale, bagged, sealed, and then printed with the production date and batch number.
