This PELLET Plant can make the pellets from the rice husk, sunflower husk, wood chips, coffee husk,wood shaving, sawdust,etc.
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
The pellet plant mainly contains
crush the big wood into small wood chips
grind the wood chips, rice husk, etc into smaller size below 5mm
dry raw material to proper moisture before making pellets
press raw material into pellets
cool down pellets and remove some moisture
remove dust, and broken pellets
pack pellets into bags of required weight, like 15kg/bag
all kinds of conveyor
transfer material among each section
PLC control cabinet
control all the pellet plant working
The detail of pellet plant:
(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 important system in the pellet pant,the hammer mill can crush the wood chips, sunflower husk, rice husk, coffee husk etc into small dust.
(3) Drying Process:
During pellet production,drying step plays high role,it is important to keep raw material in right moisture,it will make ready for next steps.In a pellet plant when moisture higher than 35%,we suggest choose Three-tier structure design, the material in the cylinder dry repeatedly three times.low energy consumption,high efficiency,high capacity. 3layer dryer’s performance is far superior to the ordinary single-drum dryer.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.
MZLH Wood Pellet Machine is the most important equipment in the pellet production plant,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.
This type pellet machine can work 24hrs in the pellet plant.
(5) Cooling Process:
After the pelletizing process in pellet plant, 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.
(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.
(7) Waste air process system (optional in whole pellet line) Dust collector :
Pluse Bag Dust Filter:
1.An unique jet device,which is equipped with a dismountable cabinet and built-in envelops,easy for maintenance.
2.Up to 1 m2 filtration area Of each bag enables its installation in a small space.
3.Compact design and high dusting efficiency(up to 99.5%),etc.
4.Widely applied for unit-machine dusting at a dump pit,a grinde,the inlet or for central dust control as well as for fines recovery in a pneumatic conveying system in grain milling and feed manufacturing industries.
5.AdditionaI applications for dust control in light industry,chemical industry,mines etc.
