500kg/h biomass wood pellet line
It mainly contains crush process,Drying process pellet making process, cooling process, packing process and waste air handing process(optional), The final pellet has good quality and meet the europe standard
The diameter of the pellets can be 6mm,8mm,10mm,12mm, the length can be adjusted according to the requirement of the client, for example 4cm,8cm,12cm
(1) Chipping Process:
Wood chipper can chip the wood logs into small wood chips , Suitable for a wide range of raw materials; the body using high-strength steel welded together, supporting the whole machine. Install two hard alloy knife on the roller, fixed with a special knife bolts. According to different material thickness, the feed roller assembly can fluctuate within a certain range by the hydraulic system. Wood chips of suitable size fall through the screen holes and discharged from the bottom of wood chipper, large pieces will continue cutting in the machine.
(2) Crushing process:
This system is one important system , the hammer mill can crush the wood chips, sunflower husk, rice husk, coffee husk etc into small dust .
(3) Drying Process:
Three-tier structure, the material in the cylinder dry repeatedly three times. low energy consumption, high efficiency, high capacity. Performance is far superior to the ordinary single-drum dryer.Multi-layer structure, improve cylinder insulation effect, increase the heat utilization. Roller speed is adjustable, precise gear drive, smooth operation, low noise. Optimized design stove, the new structure. matched with hot air filtration system of the stove to prevent flames entering the dryer cylinder. suction fan special used in water cooling system, ensure stable operation of air fan under high heat air. Afterheat can be recycled into the dryer and improve the utilization of heat energy.
(4).Pelletizing Process:
MZLH Wood Pellet Machine is the most important equipment, which have the following features:
(1). Driving Gear adopts the high precision gear transmission structure. The wear bearing is made from SKF. The motor use the Siemens Brand .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.
(2). 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.
(5) 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.
(6) 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.
