Sawdust drying machine is drying equipment specially produced by our company for wood processing plants. According to the characteristics of wood chips, our company has produced a wood chip rotary dryer specially designed for drying wood chips on the basis of the original rotary dryer. This sawdust drum dryer can fully remove the moisture in the sawdust without damaging the quality of the sawdust. The dried wood chips can be used as raw materials and processed into other products. This sawdust drying machine has the advantages of large output, easy operation, and wide application range. It is widely used in the wood industry.
Why do you need to dry sawdust with a Sawdust drying machine
Sawdust is very common in life, and a large amount of sawdust will be produced when the wood is processed. Sawdust can be reused, and as long as it is handled well, the waste from production and processing can be used well. wood chip can be obtained in various ways and will contain a certain amount of moisture. Usually, we use wood shredders to pulverize wood products such as branches, leaves, waste furniture, planks, etc., which can produce a large number of wood chips. When wood is processed into different shapes and sizes, a large amount of sawdust will also be produced. These wood chips contain a lot of moisture. If processed directly into products, these products are prone to mildew due to moisture, which affects the toughness and strength of the product and reduces the service life.
Structure of Sawdust drum dryer
The drum dryer is large-scale drying equipment that handles various wet materials. Its operation is feasible and the unit processing capacity is large. Our company re-improves the original machine based on the characteristics of high water content, flammability, and lightweight of wood chips, and produces a wood chip dryer specially designed for drying wood chips. We can also customize sawdust dryers with different capacities according to customer requirements. The main structure of the sawdust drum dryer is a slightly inclined rotating cylinder with a reasonable structural layout. It is mainly composed of cylinder, front roller ring, rear roller ring, gear, Hot air stove, discharge part, lifting plate, reducer, motor, hot air duct, furnace body, and other parts. We can also design gas burners or supporting hoists, belt conveyors, cyclones, induced draft fans, and other auxiliary equipment according to the needs of users.
The working principle of the rotary drum dryer
When the drum drying machine is working, the drum is in a rotating state. The wood chips and the hot air heated by the heat source enter from one end of the drum and exhaust from the other end of the drum. When the drum rotates, the lifter in the drum lifts the wood chips, and the wood chips can be fully mixed with the hot air. The hot airflow passes through the wood chips and takes away the moisture in the wood chips. There is a partition layer in the drum, which can disperse the material and fully contact the hot airflow. At the same time, the partition layer can increase the residence time of the material in the drum.
The capacity of the material entering the drum is about 5-20% of the drum capacity. After the wood chips are dried in the drum, they enter the cooler for cooling, and finally, the wood chips are discharged from the outlet of the cooler. The waste heat and some sundries in the materials are sucked out by the exhaust fan.
Application range of Sawdust drying machine
- Suitable for processing large amounts of wood chips. Because the wood chip drum dryer has a large production capacity, it is not suitable for household small output and is suitable for some wood processing plants.
2. It is suitable for granular and massive sawdust and can handle wet and poorly fluid sawdust. Usually, sawdust has a lot of impurities and high humidity, and the effect of using a drum dryer is good.
3. Some other materials similar to wood chips have good drying effects, such as chicken manure, bagasse, and some granular chemical raw materials.
4. Generally, the sawdust dryer can be used in the wooden pallet block production line and the molded wood pallet production line. When producing wooden pallet block and sawdust pallets, the raw materials contain moisture and the sawdust needs to be dried.
Advantages of wood chip drum drying machine
- The drum drying machine produced by our company has a sealed structure, which can reduce heat loss and improve thermal efficiency.
2. The drum dryer has a good drying effect. Because the wood chips are highly dispersed in the airflow, the entire surface area of the particles can be in contact with the hot air.
3. The drum dryer has a simple structure, a small footprint, and is easy to install and maintain.
4. Large processing capacity and high thermal efficiency. The thermal efficiency can reach 60%.
