Sawdust dryer machine is specially designed for Drying Saw Powder which can get rid of the water from the wet saw powder as need. The moisture content of the wet saw powder can be reduced from about 40-50% to be about 15% or as need.
The resource of saw powder can be from saw mill, waste of paper plant, etc. Here we takes the waste of paper plant as sample.
The waste of paper plant mainly is wet material like saw powder, but its moisture content can be up to 70%. Even you use your hand to squeeze the wet sawdust, the water will come out.
As the waste sawdust from paper plant is too wet, in order to use it to produce biomass pellet, we have to use reduce the moisture content of wet saw dust to be about 18%.
Here please note that both of too wet and too dry saw dust are not suitable for producing the biomass pellet and briquette.
Drying Saw Powder Machine have the features as follows:
◆ High drying intensity: since the material is highly dispersed in the gas stream. The entire surface area of the particles is entire effective area of the particles for drying.
◆ Short drying time.
◆ Simple and compact structure, small floor area needed, convenient installation and maintenance.
◆ Large drying capacity, high heat efficiency can be more than 70% when it is free water.
Drying Saw Powder plant mainly consist of hot air furnace, feeder, air duct tube, cyclone dust separator, the induced draft fan. The sawdust rotary dryer, rods machine and carbonization furnace are generally combined to form the configuration, chimney, electric control box, etc.
