The YULONG series vertical efficient centrifugal pellet mill incorporated the distinguishing features of all kinds of pellet mill at home and abroad. It has unique design, reasonable structure, lower energy consumption, higher efficiency, more stable in motion and much longer service life. It is a YULONG`S patent product which filled a gap of vertical pellet mill.
It is wide applicability to the materials which is hard to molding and adhesive: ex. Palm fruit fibre and shell, rice husk, peanut shell, sunflower seed shell, agro-residues, timber processing residues, industrial residues .
XGJ series pellet mill has a variety of applications in feed plants, woodworking factories, biomass fuel plants, fertilizer plants, and chemical plant etc. It is an ideal dense compression molding equipment.
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
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.
