Waste materials are tested for their chemical composition to decide on their suitability and to select a proper mix.
Sun dried materials containing approx. 10-15 % moisture is suitable for Pelletising. However if material has higher moisture content it needs to be dried before use.
Material is screened, chopped and ground to get the desired size and bulk density and is pneumatically transported into storage bins. This helps in separation of the heavier & metallic particles and also unifying the moisture content in the material. Air used is hot or wet as the case may be, for control of moisture.
Material from bin is discharged to the Pelletising machine through extraction and conditioning screw. Binder and steam may be added. Pelletising is achieved at very low speed of pelletising.
Pellets are cooled by pellet cooler or ambient air and packed in bags.
