Sawdust Dryer

Sawdust Dryer

We also called the sawdust dryer as vertical dryer, it is air-flow type dryer, with stable performance and top quality

Type capacity(kg/h) power package size weight(kg)
QHJ-4 300-400 4kw 1.5X1.22X0.98+2.3×1.4×1.5m 1500
QHJ-6 400-500 5.5kw 1.45×1.2×1.0+2.5×1.9×1.5m 1800


Sawdust Dryer
Sawdust Dryer for drying raw materials with less humility, such as sawdust powder, staw powder and so on, the drying scope normally from 20%-40%. the final humility will get from 8-14%.

Main features of Sawdust Dryer

1. The usage for sawdust dryer machine
A: it needs to dry sawdust before making briquettes
B: other indusctry usage

2.The raw materials  of vertical dryer should be less than 5mm,
low consumption, high capacity, easy operation and maintenance, etc. In addition, the round places of pipes can be changed to any angle which can save space and solve plant dimension limitation.

3. Regarding QHJ-4 and QHJ-6 Type Dryer,it is suitable to process materials which moisture content between 20%-40%.It can reduce the humility to 8%-12% one drying time.

4.Heat resourse: by gas or wood biomass, it needs to burn the wood biomass waste as around 30-40kg/h

Working process of Sawdust dryer

The dryer is equipped with two fuel boilers, inlet, steel pipe, exhaust blower (fan),  cyclone. Wet materials are put into the hopper. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air is flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock. This wood dryer reduces the moisture to 8~12% with the advantages of low cost consumption and high efficiency.

Rotary Dryer

Rotary Dryer

Rotary Dryer is with the following parts

Burner, rotary body, necessary pipes, rotary body fans, and so on

Rotary dryer
Rotary dryer with suitable thickness of rotary body, also famouse brand fan and bearing. could drying the raw materials moisture 20-70% into less than 14%

We are doing the special design for rotary body inside, it is suitable for sawdust with hot air contact evenly, also improve rotary dryer capacity


Rotary dryer body with good design
Rotary body special design inside, it is mainly for improving the capacity and working performance

Rotary dryer drying sawdust in worksite

Rotary Dryer in worksite
Rotary dryer in worksite place, this is in our Malaysia clients place, it is the line for making wood briquettes and pellets. Rotary dryer is as first process

Main feature of Rotary dryer

1. We could match sawdust conveyor for sending sawdust into the dryer machine
2) It includes the burner, rotary body, fan, base, gear, necessary pipes and so on
3. it is suitable for raw materials humility as 20-70%, final humility is as 8-14%
Rotary type dryer shows the features of perfect drying effect, easy operation, high efficiency and easy control of drying. It takes advantage of the stability of roller and homogeneity of air.

The following question maybe you are considering when you choosing Rotary Dryer

. What the rotary dryer mainly usage scope

This dryer can dry many kinds of materials which contain moisture, such as sawdust, biomass, coal, coal slurry, slag, industrial waste, and clay stone. They are widely used in building materials, metallurgy, and chemical industry.


2. what the rotary dryer made of?


The dryer is madeof rotary body, lifting blade, driving device,

supporting device and sealing ring.


3. Can I use the coal or gas as the heating source?


Yea, you can use coal, gas, electricity, oil and wind power to heat the dryer machine.


4. How the rotary dryer to work process


The raw material plate is arranged conveniently to allow adjustable angle positions.

The material to be dried is inserted to the rotary cylinder through the raw material

plate. Hot air flows within the cylinder causing the separation of water from the material

by converting it into vapor which is discharged into the atmosphere.

At this point, the material becomes dry.




Wood Dryer

Wood Dryer

Wood Dryer machine is divided into two types, the vertical dryer and rotary dryer

Vertical dryer is for smaller capacity, Rotary Dryer is for having bigger capacity

Wood Dryer is first process to get the drying wood sawdust to make pellets or briquettes, or making charcoal powder

Wood Dryer
Wood Dryer machine mainly drying the sawdust into smaller humility

We also have another model wood dryer machine for drying wood chips. the structure is a little different

the discharge port is doing the sepcial design for loading wood chips out, read the picture,pls

wood chips dryer
Wood Chips dryer is mainly for bigger size wood chips, after drying the wood chips, it could be crushing directly

Wood Dryer Main Usage Scope

Wood Dryer main is the first process to drying the sawdust as less moisture, it is ready to make wood pellet fuel, straw briquette fuel, charcoal machinery, sawdust briquettes, and agricultural engineering industries. For example, the drying of agricultural fiber materials such as corn straw, soybean straw, cotton stalks, wheat straw, sorghum stalks, sawdust , wood shavings, ginkgo leaves, mulberry leaves
