Proxipel: The Mobile Pelletizing Solution (video)

Producing pellets as close as possible to the deposit: that is exactly what this video from thePROXIPEL mobile pelletizing unit . It showcases PROXIFLEX, a mobile, integrated pelletizing unit mounted on a semi-trailer, designed to perform all key stages of production, from biomass feeding to pellet output. The goal: to process biomass—which is often bulky and moist—on-site, reduce upstream and downstream transportation, and ensure local utilization.

What You’ll Actually See in the Video

  • The “factory” semi-trailer and its on-site setup (the “local production” approach).

  • The end-to-end processing line: feeding, size reduction, drying, pressing, cooling, and then conveying/blowing the pellets into an external container (dump truck, trailer, silo, etc.).

  • Typical internal components of a miniaturized pellet production line: hopper, conveyor/screw, grinders, dryer, press, and control via an interface (settings/controls).

The Process Presented (Step by Step)

  1. Feedstock: Pre-shredded biomass is poured into a large hopper (particle size: ≤ 5 cm).
  2. Particle size reduction: The material is then conveyed through two grinding stages until it reaches a fine particle size (1 to 3 mm) suitable for the press.
  3. Drying: The biomass passes through a dryer (drum-type/hot-air), designed to significantly reduce the moisture content from 50% to 10% in a matter of minutes, depending on conditions and the moisture content of the incoming material.
  4. Processing: Pass through a mixer to adjust the moisture content to the target level (~13%); additives may be added as needed, depending on the material and the desired quality.
  5. Compression/pelletizing: The press compacts the material to form the pellet.
  6. Cooling & Discharge: The pellets are cooled and then blown into the selected container (dump truck, trailer, silo, etc.).
