Wood Pellet Machine/ Wood Pellet Making Machine/ Wood Pellet Mill XGJ850

This is our 8th generation centrifugal highly efficient pellet machine, which is our patented product, we are its inventors and creators. Please look at the picture, it showed us the development of our pellet machine. From the advent of the first generation of machines in 2009 to the 8th generation in 2021. We are upgrading based on how to improve the stability of the equipment and how to extend the life of the work-piece. It is the crystallization of the wisdom of all our Yulong people.
Other similar products on the market are imitating us.
Next,  let me tell you the advantages and features of the 8th pellet machine
The pellet machine is mainly composed of four parts: the pellet mill, the lubricating oil pump, the dust removal and the electric control cabinet.
1、The power is 250KW, capacity is 3-4tons/hr. The motor is directly connected to
the gear box to increase the conversion rate of kinetic energy and improve production efficiency.
2、The gear box adopts three-stage gear deceleration, the carrying capacity is 5 times
larger than the old model, and the service life is super long.The bearings of gear shafts are adjustable structure.The bearing can be adjusted without unloading the machine after long-term running of wear.The gearbox comes with a lubricating cooling system, it can cool down the lubricating oil without stopping the machine to ensure long-term operation.
The gearbox lubrication system is equipped with flow detection and over-pressure protection, which can prevent equipment failures caused by poor lubrication effectively.
3、New feed system. The external setting of the material dial completely solves the
problem that the dial material system is easily corroded by high temperature steam. It is a major innovation of the eighth generation pellet machine. In the material shifting cover, except for the material shifting turntable, other non-moving parts in contact with materials and steam are all made of stainless steel, which solves the corrosion problem of metal materials fundamentally.
4、Core component-ring die: It is made of wear-resistant stainless steel material,
quenched in a vacuum furnace, and the die has uniform hardness, no breakage, and super wear-resistant; the die holes are processed by high-speed gun drilling, the holes are evenly arranged, and the inside of the holes is smooth.
5、The core component-roller: the roller adopts super wear-resistant alloy welding process, instead of the past surface carburizing treatment. Long life span, while realizing the protection of the ring die.

This is our main equipment-pellet machine. This is our XGJ850 model. Power supply is 250KW, the capacity is 3-4ton/hr. We also have XGJ560 model .Power supply is 132KW, the capacity is 1.5-2ton/hr. You can choose one model according to your needs.

Yulong Wood Pellet Machine Features

The main gear box

The main gear box is precisely cast by HT500 casting gray iron. Its casing and cover are processed separately by ”NEWAY” CNC gantry processing center. The boring and milling process of its 8 bearing positions can be completed in once clamping by SNK CNC five-axis gantry processing center,which is a world-class Japanese CNC gantry processing center valued RMB 12 million. The concentricity tolerance and positional tolerance of its quad-gear shaft bearing position can be controlled within 0.02mm. Its gear wheels and gear shafts ,which is made of forging alloy steel, are conducted the carburizing and quenching process after rough machining, then precisely ground by German NILES gear cutting machine, so they are running stable,noiseless,in long service life. The main gear box is coupled with motor through a combination of coupling and quincunx elastomer; which is easily maintenance, low cost,running in noiseless and with long life span vulnerable spareparts.

The ring die and Rollers

Ring Die

1. The ring die is made of forging stainless steel. It`s processed by CNC high speed four-spindle drilling machines. The holes of the ring die are burnished and arrayed evenly.  It makes the discharging smoothly .

2.  It`a made the quenching process by vacuum quenching furnace,uniform in hardness, minute in deformation and without oxide coating on its surface.


The rollers are made of forging alloy steel. They are welded the special wear-resistant materials on surface by welding robots after the teeth milling. Their wear-resistant layer is 8mm in thickness and 62 degree in hardness. They are higher in hardness, thicker about their wear-resistant layers, more effective on taking materials and longer service lives than both kinds of rollers hardened through 20CrMnTi hardening technology and hardened bearing steel rollers.

General questions to design the production line for you?
1. What is your raw materials? (to confirm mould pressure ratio of machines )   2. What is the moisture content of your raw material?3. How many output capacity do you want per hour / month/ year? Note: If the moisture is high, you need a dryer, becuase the suitable moisture content to enter pellet machine is 13-15%. Andplease provide us above detailed information, then we would design the most suitable production line with reasonble offers.
