6ton per hour

From 2000, we constantly develope our machines in order to satisfy the need of biofuel energy. Now our SZLH-Series pelleting machine are particularly appropriate for products which are difficult to pellet, such as the Wood Waste (Logs, Wood Shavings, Wood Chips, Sawdust), Straw (Miscanthus, Bagasse)and the other Biomasses. Our pelleting machine with a drive power from 15 kw to 160 kw to make different size pellet. We plan and calculate wood/straw pelleting plants according to the requirement of the customer considering the capacity and the local conditions between 0.5-6ton/hour. Till now, we have finished installing whole line for 10 sets turn-key projects on wood pelleting in China with 1-2ton/ hour.

 

Introducing for the line

This line macke the wood pellet with sawdust. collect the material and mix, adjust the quality, make one, small and roundish thing to cool dry, Sift the process of grading to form. The technological process are rational in succession , every unit performance is good, the aircrew structure is compact ,The area of occupation of land little, the energy consumption bottom, it is convenient to operate it and maintain.

It is also used for kinds of grain straw for the pellets.

 

Energy Consumption: Water 40-60kg/1h, Coal 80-120kg / 2ton raw material with 30% moisture

Explanation for the line

l Â Ã‚ Ã‚ Ã‚ Ã‚ Ã‚  Wood Crushing system

 

Use Wood crusher to crush the chips into power alike sawdust . if the size of raw materials is bigger than 5cm,it is necessary for using big chipper,such as drum chipper ,firstly it crush the big branch into small size ,then use wood crusher to crush it into sawdust .

l Â Ã‚ Ã‚ Ã‚ Ã‚ Ã‚  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.

l Â Ã‚ Ã‚ Ã‚ Ã‚ Ã‚   Pelletizing Process:

SZLH Wood Pellet Machine 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.

l Â Ã‚ Ã‚ Ã‚ Ã‚ Ã‚  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, so 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.

l Â Ã‚ Ã‚ Ã‚ Ã‚ Ã‚  Packing Process:

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