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.

Rollers

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.
