Process: The wet raw material is fed into the drum dryer with the help of in-feed screw conveyor. The raw-material in the rotating drum gets in direct contact with heat generated from furnace. The moisture from raw-material gets evaporated and further sucked by Id Fan(s). The dried material gets discharged from the discharge screw conveyor.

Use: Rotary Drum Dryer is used for drying the moisture content from the raw material which is having the moisture up-to 50%. The dried material can be used as a Biomass for heat generation, making Biomass Pellets & Biomass Briquettes or for other purposes.

In-put raw materials: It possesses the ability to process material having considerable variation in size and composition because this dryer is less sensitive to particle size as compared to other dryers, thus it can be used for a wide variety of raw materials. Any agricultural or forest waste (in chipped or shredded form) such as: sawdust, press mud, bagasse, paddy straw, sugarcane straw, coir pith, soybean husk, mustard straw, wood chips, veneer waste, tree barks, wood peeling, municipal solid waste, rdf( refuse derived fuel ) etc, can be dried using this dryer.
