Factory price flash type drier for sawdust with high performance
1. introduction:
Drying is important for the proper preparation of materials prior to their briquetting. To make good quality briquette with high density, it is very important to control the moisture content of raw material to 8-12% before loading them into biomass briquette machine, so sawdust and other kinds of biomass need to be dried first.
Flash dryer ( airflow type dryer) is a pneumatic drying system used to dry products requiring the removal of free moisture. Flash dryers are using the heat from the airsteam.
2.Typical Applications of Flash Dryer:
(1) Dryer Model HGJ-I, HGJ-II, HGJ-III for biomass materials with lower moisture content 12-25%
In the biomass briquetting plant ,the moisture reducing rate of the dryer HGJ-I, HGJ-II, HGJ-III is 8-12%. This series of flash dryers are equipped with one hot air boiler, suitable for drying raw material with moisture content less than 20-25% for biomass briquetting.If the moisture content of the raw material for biomass briquetting is higher than that, it will need two or three times to dry to achieve the requested moisture content for biomass briquetting plant.

Working Principle of Flash Dryer
Wet material is input into the hopper. The dryer is equipped with two fuel boilers, inlet, steel pipe, exhaust blower (fan), air lock and cyclone. Wet materials are input 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.
Structure Of the flash dryer
thisdrier is widely used to dry the sawdust likesize grain. It is made up of heat stove,tube,impulse jar,function tube,fan,sperator.
Heat Stove: it’s made up of armor plate,firebricks,and stove chain. It’s used to supply the heat to the drier.
Channel Tube:It’s the passway to transport the material to the rotary body and the impulse jar.
Impulse jar and fuction tube: Used to mix the material with heat thoroughly to reduce the water.
Fan is made up of fan wheel made of the 400 model armor plate,4kw fan. It’s used to supply power to transport material into seperator.
4,Cautions of operation the dryer
1,The speed of the charging material mainly base on the primary moisture. The charging speed is high when moistuer is low. When the moisture is high the charging speed is low.
2,Every 10 days add lubricating oil to the bearing.
3,Check the tube often, remove the ash blocking the dust removal hole
4,To make sure the material is the sawdust size less than 5*5mm. Commonly before drying the material need separated by the screen to remove big size material.
5,If the impulse jar is blocked open the hole underside to lease the block.
6,The high temparture is prohibited.
7,Discharging material with high temperature is prohibited in case of the fire disaster.
8,Before the production please check if the electrocircuit is correct
