Pelletizing is the process of making Agro-Forestry into solid fuel. The objects are used for burning purposes.
Pelletizing is the process of making waste materials into solid fuel. The objects are used for burning purposes. Wood Pellet can be made from any types of Agro-Forestry waste: Groundnut-shell, Sugarcane Biogas Caster Shells/Stalk, Saw dust, Coffee husk, Paddy Straw, Sunflower Stalk, Cotton Stalk, 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 materials, we fit out the suitable Crushing machines. The BX-Series Combined Chipping and Crushing Machine are used for the raw Log with diameter <200mm; SFSP-series Hammer Mill is widely used to crush each kinds of straw, wood chip, tree branch, bark and the leftover bits from agricultural wastes. The best moisture content in the Crushing Process is less than 20%, and the thickness of the wood chip is less than 5mm.

2. Drying Process:Biomass Pelleting Plant

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 reduce the moisture from 50% to 10%, saving about 30% energy consumption by comparing with the old Rotary Dryer. Our burning stove is fueled by coal and wood materials, which can save electricity consumption largely. If the users want to use other fuels, 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, features as the following:


(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 one, the microcomputer will start the round closed Auto-Lubrication System to lubricate the bearings, which completely 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 the biggest bearing manufacturer of China, according to our special requests. The ring die adopts the hoop fastening method, which increases the speed of discharge by 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. Our heating treatment is also different from the other domestic manufacturer, our carburizing treatment makes the depth of hard facing to 2mm, which improves the anti-abrasion of the ring die and roller more than 10 times, it can save the cost of the production 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 to use Cooler to reduce about 3-4% moisture, such wood pellet is easy to store.

Noticing the feedback from some foreign clients, we were reminded that the local climate is very humidity; they hope to cool the wood pellet with moisture 7-8%. In order to satisfy the different needs from different clients, we developed one new kind of Stabilizer Combined Cooler.

5. Packing Process:

After cooling, the wood pellet will not directly enter the fuel process, avoiding the wood pellet which was affected with damp. The packing process is necessary. In this process, we assemble our domestic best Semi-Auto Packing Machine to you.
