sawdust-rotary-drum-dryer

Rotary drum dryer is a type of industrial dryer that can be used to used to dry materials such as biomass, sludge, wood chips, sawdust, and other organic materials. It is commonly used in the wood processing industry, as well as in the biomass and biofuel industries. They are efficient and cost-effective, and can handle large volumes of sawdust.

Rotary drum dryers can also be used in the agricultural, chemical, and mineral industries for drying a variety of materials such as grains, fertilizers, and ores. They are also used in the food industry for drying fruits, vegetables, and other food products.

Working Principle

This kind of dryer machine works by feeding sawdust into a rotating drum, which is heated by a burner. As the drum rotates, the sawdust is lifted and cascaded through the hot air, which evaporates the moisture.

Drum

The drum is the main component of the rotary drum dryer. It is a cylindrical shell made of steel or other materials that rotates on its axis. The drum is usually slightly inclined to facilitate the movement of the material through the dryer.

The drum is also equipped with lifting flights or paddles that help to lift and tumble the material as it moves through the dryer, ensuring that it is evenly exposed to the hot air and that it dries uniformly.
