Output requirements: Select models according to daily/annual ,
output (small household 0.5-1 tons/hour, medium 3-5 tons/hour, large 10 tons/hour or more).
Uses: household heating (small flat die), commercial heating (ring die), industrial power generation (large ring die or stamping type).
Specification: Common diameter 6-10mm.
Critical component quality:
Mold material: preferred alloy steel (such as 20CrMnTi), heat treatment hardness, life ≥500 hours.
Roller durability: Tungsten carbide coated roller can extend the service life by more than 30%.
Transmission system: Gear box needs IP54 protection grade, bearing brand recommended SKF or NSK.
Applicable material classification:
Typical ingredients:
wooden materials wood chips, sawdust, wood shavings, twigs, bark, wood processing waste.
Features: High lignin content (natural adhesive), easy to form, high particle calorific value (4200-4800 kcal/kg). Adaptation model: ring die particles machine (high pressure molding effect is good.
agricultural wastes
Straw: corn straw, wheat straw, rice straw.
Shelly: rice husk, peanut shell, coconut shell, palm shell. Other, bagasse, cotton stalk, haulm.
Others: bagasse, cotton stalk, bean straw.
Features: High fiber content, some raw materials need to be crushed to 3-5mm, may need to add adhesives (such as 1-3% starch or lignin).
Suitable model: high pressure ring die or stamping pellet machine (for high fiber raw materials).
Energy plant
Energy plant
Typical ingredients: switchgrass, Miscanthus, sweet sorghum, fast-growing forest (e.g. eucalyptus).
Features: Specially planted for energy production, need to control the harvest moisture (≤20%).
Other organic waste
(various types according to the actual material, Shinread engineers do selection)
Preprocessing requirements crushing: particles machine feed size usually < 5 mm (straw classes need to use hammer type crusher).
Pretreatment :
Drying: Roller dryer or natural drying to the target water content.
Mixing: Mixing a variety of raw materials can improve the molding rate (such as wood chips + straw by 7:3 ratio).
