high capacity best selling wood waste dryer ( flash type)

specifictaion of the flash dryer HJ-7

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.

Features of sawdust dryer:

1.high degree of mechanization, large production capacity, continuous operation

2..Simple structure, excellent resistance, stores running smoothly through the cylinder, operating convenience.

3.low power consumption and low maintenance costs.

4.Applicable to a wide range of dry, product, good uniformity

Sawdust dryer machine is widely used in building materials, metallurgy, chemical industry, cement industry and drying of limestone slag, coal, slag, clay and other materials. Mainly by the rotary machine, Yang plate, transmission, seals and other support devices and components. In structure, produced, high output, low energy consumption and easy operation.

2.Typical Applications of Flash Dryer:

Ideal for removal of moisture from free flowing materials which is light and small like sawdust, rice hull, milled stalks etc.; suitable for small production scales below 700kgs per hour.
Comparing with rotary dryer, the flash dryer has the advantages of low energy consumption and low cost. It is in simple design but have good effect as well.

Suitable fuels for the boiler are wood waste, coal etc. The failed biomass charcoal can be fed into the boiler, too.

(1) Dryer Model BHGJ-I, BHGJ-II, BHGJ-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.

(2) Twin boiler dryer model NHGJ-I, NHGJ-II, NHGJ-III for higher moisture content 20-50%

In the biomass briquette plant ,twin boiler dryer is a newly developed dryer with two hot air boilers, it is suitable for drying raw material with moisture content of 20% -50% for biomass briquetting. It can reduce moisture from 20%-50% to 8-12% for biomass briquetting only one passage or one time. PS: For raw material of moisture 20-35%, only fire and use the first boiler, no need to use the both.

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
