Rotary Sawdust Dryer

Sawdust dryer is important and indispensable drying equipment in the process of production mechanism charcoal. The materials of the timber which have been crushed can be produced to the fashioned mechanism stick through the sawdust dryer and the rod making machine.

Sawdust dryer is important and indispensable drying equipment in the process of production mechanism charcoal. The materials of the timber which have been crushed can be produced to the fashioned mechanism stick through the sawdust dryer and the rod making machine. Then the fashioned mechanism sticks are made into the mechanism charcoal by the coking furnace.

Sawdust dryer mainly has two types. One is rotary sawdust dryer, one is airflow sawdust dryer. Rotary sawdust dryer is for the big processing capacity, and the airflow sawdust dryer is for small processing capacity.

Sawdust Rotary Dryer Heating Method

1.By gas: it means use the gas as the fuel to provide hot air for the rotary drier, then gas burner is necessary.

2.By coal or wood and others: It means use the coal, wood or other material as the fuel to provide hot air for the rotary drier, then the hot air furnace or generator is suitable.

Generally speaking, when the customer choose the fuel need to consideration the investment, according to the local situation choose the most economical materials for heat source

Sawdust Rotary Dryer Features

1. Easy to transport and install.
2. High self-insulation thermal efficiency of 70% inside the drum.
3.Moisture content requirements is adjustable, depending on clients’demand.
4. Guaranteed dry effect (≤ 10% after drying)

The Component of sawdust rotary dryer:

Rotary drum dryer is composed of cylinder, feeding and discharging device, roller ring, small gear and big gear, carrier roller,lifting plate,reducer,motor, feed chute,dust collector, fan.
In addition, we can design the corresponding heat source system according to customer requirements, such as coal gasifier, biomass furnace and burner, etc. The rotary drum dryer also can be equipped with the corresponding auxiliary equipment, for example: dosing feeder machine, belt conveyor or bucket elevator, cyclone, draft fan and so on.

The Working Principle of sawdust rotary dryer

1.Wet materials are sent to the hopper by belt conveyor or bucket elevator.
2.Through the feeding hole set that in the spiral guide plate, the wet material get into drying cylinder.
3.Materials in drying cylinder will be raising by the equally distributed lifting plate and fully contacted with the hot air.To achieve the heat transfer,mass transfer drying purpose.
4.Dried materials discharged at the end of the cylinder, transported out by the conveyor, finished the drying process.
