(Italiano) PERCHE’ DOVREI PRODURRE IL PELLET DA SOLO?
WHAT MATERIALS CAN BE PELLETIZED?
ALMOST ANY MATERIAL: MAINLY BIOMASS WASTES (FOR EXAMPLE: SHAVINGS, SAWDUST, MICRO-WOODCHIP, AGRICULTURAL WASTES, PRUNING, ANIMAL MANURE, ETC.). THE MATERIAL MUST BE REFINED BEFORE ENTERING OUR MACHINES AND ITS SIZE SHOULD BE < 10 MM.
WHAT MOISTURE CONTENT IS REQUIRED?
10% MOISTURE CONTENT IS REQUIRED. IF THE PERCENTAGE IS HIGHER, THE MATERIAL MUST BE DRIED BECAUSE WATER CANNOT BE COMPRESSED.
WHAT SHOULD BE ADDED TO THE RAW MATERIAL?
THE ADDITION OF CONDITIONER (STARCH OF VEGETABLE ORIGIN SUCH AS CORN OR WHEAT STARCH) TO THE RAW MATERIAL IS RECOMMENDED (ABOUT 2%).
WHAT HAPPENS INSIDE A PELLETIZING BODY?
IN THE PELLETIZING BODY THE THERMOFORMING OF THE MATERIAL OCCURS, THIS PROCESS IS ORIGINATED FROM THE FRICTION OF THE RAW MATERIAL INSIDE THE CYLINDER OF COMPRESSION, WHERE THE MATERIAL IS SUBJECT TO OVERHEATING AND AS A RESULT COMPACT CYLINDERS (PELLET) ARE ORIGINATED.
WHAT IS A PELLETIZING BODY?
THE MAIN BODY OF OUR PELLET MILLS IS A THICK STEEL CYLINDER, WHICH IS TURNED AND ZINC-COATED. IT ENSURES STRENGTH AND DURABILITY.
WHAT IS COMPRESSION?
THE COMPRESSION IS THE DWELL TIME OF THE RAW MATERIAL INSIDE THE DIE. THIS DURATION VARIES ACCORDING TO THE MATERIAL, FOR EXAMPLE HARD WOODS (SUCH AS: BEECH, DURMAST, CHESTNUT OR ASH) REQUIRE LOW COMPRESSIONS, WHILE HIGH COMPRESSIONS ARE REQUIRED FOR RESINOUS WOODS (SUCH AS: PINE, FIR OR LARCH).
WHAT ARE THE FAST-WEARY COMPONENTS OF A PELLET MILL?
THE FAST-WEARY COMPONENTS OF A PELLET MILL ARE: THE DIE, THE PRESSURE ROLLERS AND THE BEARINGS. ANOTHER CONSUMABLE IS THE GREASE THAT IS REQUIRED FOR THE LUBRICATION OF THE BEARINGS.
