How does the PSi Pellet Mill compare to other products on the market?
The PSi Pellet Mill’s innovative technology provides a substantial change in the way wood mass is formed into pellets, resulting in a substantial reduction in production power demand compared to traditional methods. The benefits of the PSi Pellet Mill are:
- Higher tolerance for moisture content (between 18% - 25% compared to traditional mills at 6% - 10%) means in some cases drying can be eliminated.
- No cooling tower required with the PSi Pellet Mill, lower capital costs up front and energy savings year after year.
- Produces the highest density pellet on the market (up to 93lbs/ft³ vs. traditional mills at 82 lbs/ft³)!
- Interlocked particle layers create a denser pellet, vs. flat particle layers of traditional pellet mills.
- Variable die speed for adjusting pellet process for optimum quality vs. fixed die speed on traditional pellet mills.
- No additives or binders required during pellet process.
- Dies engineered for 4000 hours vs. 2000 hours with traditional pellet mills.
- Pellet removal from dies by air suction with fines vs. traditional mills that require pellet removal by conveyors to cooling tower.

Can pellets be made of any other materials?
Yes, there are Agricultural pellets that are used for industrial operations. The PSi Pellet Mill can produce Agricultural pellets can from many types of materials, for example: hay, straw, spoiled grain, canola sludge, switch grass, willow and even peat moss. BioEnergy crops are also becoming increasingly popular (switch grass, willow, elephant grass).
