Specifications

1:Complete wood pellet plant for 1000-8000kgs/h
2:CE approved
3: Main spare parts: Ring die

Complete wood pellet plant is the process of making waste materials into solid fuel. The objects are used for burning purposes. Wood Pellet can be made from any type of Agro-Forestry waste: Groundnut-shell • Sugarcane Biogases • Caster Shells/Stalk • Saw dust • Coffee Husk • Paddy Straw • Sunflower Stalk • Cotton Stalks • Tobacco waste Mustard Stalk • Jute waste • Bamboo Dust • Tea waste • Wheat Straw • Palm husk • Soybeans husk • Coir Pitch Barks/Straws • Rice Husks • Forestry wastes • Wood Chips and many other Agro wastes.

1. Crushing Process:

Depending on the different input material, we fit out the suitable Crushing machines. The BX-Series Combined Chipping and Crushing Machine is used for the raw Log with diameter <200mm; SFSP-series Hammer Mill is widely used to crush each kind of straw, wood chip, tree branch, bark and leftover bits from agricultural wastes. The best moisture content in the Crushing Process is less 20%, and the thickness of the wood chip is less 5mm.

 

2. Drying Process:

The best moisture content to pelletizing is about 14-16%. Our new Air-Current Rotary Dryer is made up of Burning Stove and Main Rotary Dryer, which can realize to reduce the moisture from 50% to 10%,and save about 30% energy consumption comparing the old Rotary Dryer. Our burning stove is fueled by coal and wood material, which can save electricity consumption largely. If the users want to use the other fuel such as gas and electricity, one Burner is necessary, but the extra cost will be charged.

 

3. Pelletizing Process:

MZLH Wood Pellet Mill is the most important equipment, which have the following features:

(1). The lubrication system for wood pellet mill adopts the tracing and inspecting system controlled by the microcomputer. When the temperature of the bearing is over the normal temperature, the microcomputer will start the round closed Auto-Lubrication System to lubricate the bearings, which complete solved the trouble of lubricating roller depending on the operation experience. The Lubrication System is made up of the tracing and inspecting system controlled by the microcomputer, auto-lubricating system on time and compelled lubricating system by hand.

(2). Driving Gear adopts the high precision gear transmission structure. The wear bearing is made from China Biggest Bearing Manufacturer according to our special requests. The ring die adopts the hoop fastening method, which is increasing the speed of discharge comparing with the past bolt fastening method. As a result, the capacity is 10-15% higher than the belt transmission structure. 

(3). As per the ring die and roller of the wood pellet mill, we have the fine machining with the alloyed steel, such as 20 CrMnTi and 40Cr; and stainless steel, such as 4 Cr13 and 3 Cr13. And our heating treatment is also different from the other domestic manufacturer, our carburizing treatment make the depth of hard facing to 2mm, which improve the anti-abrasion of the ring die and roller more than 10 times, it can save the production cost heavily.

 

4. Cooling Process:

After the pelletizing process, the temperature of the wood pellet is about 60-80 degree, and the moisture content of the wood pellet is about 15%, so we need use Cooler to reduce about 3-4% moisture, such this the wood pellet is easy to store.

But considering the feedback from some foreign clients, the local climate is very humidity; they hope to cool the wood pellet with moisture 7-8%. In order to satisfy the different need from different clients, we develop one kind of new Stabilizer Combined Cooler.

Wood pellet production line has sold to lots European countres, like Turkey, Swden ,Hungary, Spain,Bosnia,Romania, Bulgaria,etc!
