SELF-PRODUCED PELLETS ARE CHEAPER BECAUSE THE RAW MATERIAL IS OBTAINED FROM PROCESSING REMNANTS AND THEREFORE WITHOUT COST. IN ADDITION, THE ADDITIONAL COSTS OF PACKAGING AND TRANSPORTATION ARE AVOIDED, SAVING US ANOTHER PART OF THE EXPENSE. USING IT AS FUEL WE WILL HAVE A THIRD SAVINGS, THIS TIME ON THE UTILITY BILL. LAST BUT NOT LEAST, YOU CAN ALSO SELL IT; THIS WAY IT WILL ONLY TAKE A SHORT TIME TO PAY BACK THE INVESTMENT OF THE MACHINERY.

ALMOST ALL MATERIALS: MAINLY BIOMASS WASTES (E.G. SHAVINGS, SAWDUST, MICRO-CHIPS, AGRICULTURAL WASTE, PRUNINGS, ANIMAL DUNG, ETC. PREVIOUSLY REFINED WITH A GRAIN SIZE < 10 MM.

THE MOISTURE CONTENT SHOULD BE ABOUT 10%, IF THE RAW MATERIAL HAS A HIGHER MOISTURE CONTENT IT IS NECESSARY TO UNDERGO A DRYING PROCESS

TO THE RAW MATERIAL IT IS RECOMMENDED TO ADD AMENDANTS (STARCHES OF VEGETABLE ORIGIN e.g., OF MAIS, OF FRUMENTO) AT A PERCENTAGE OF ABOUT 2%.

DURING THE PROCESS, THERMOFORMING OF THE MATERIAL OCCURS DUE TO THE FRICTION OF THE RAW MATERIAL INSIDE THE COMPRESSION CYLINDER, IN WHICH THE MATERIAL IS SUBJECTED TO OVERHEATING GIVING RISE TO THE COMPACT CYLINDER (PELLET).

THE CENTRAL BODY OF OUR PELLET MILLS IS A THICK STEEL CYLINDER FULLY TURNED AND GALVANIZED, WHICH IS ESSENTIAL TO ENSURE EFFICIENCY AND DURABILITY.

COMPRESSION IS THE PERMANENCE TIME OF THE FIRST MATERIAL INSIDE THE TRAFILE VARIABLE ACCORDING TO THE TYPE OF MATERIAL e.g., FOR HARD WOODS (BEECH, OAK, CHESTNUT, ASH) LOW COMPRESSIONS, FOR RESINOUS WOODS (PINE, FIR, LARCH) HIGHER COMPRESSIONS.

THE WEAR PARTS IN A PELLET MILL ARE: THE DIE, THE PRESS ROLLERS AND THE BEARINGS. WE ADD GREASE AS A CONSUMABLE FOR GREASING THE BEARINGS.
