After the working process of sawdust pellet mill, you should use the oil material with 20% grease to clean the die hole for about 5 times or 10 times. To make oil materials take the place of raw material in ring die, you can make the discharging work much easier for the next run of sawdust pellet mill.
For ring dies with low opening rate, you can use the drill to make materials for blocking holes out. If this way is useless, you can immerse the ring die in hot oil for several minutes. When the die holes inflate, you can clean the materials for blocking holes out. In terms of the new ring dies without being polished, you should ensure them qualified in the degree of finish.
If not being removed out, metal dust and oxides in the holes of new ring die can increase the resistance of raw materials to pass through the die holes. What’s worse, the biomass pellets produced by sawdust pellet mill of FTM China Machinery would be very coarse in surface, easy to fracture and poor in quality. Therefore, holes of ring die should be polished.
Known as the NO.1 brand of sawdust pellet machine, FTM China Machinery has enough strong technological support. With three state-level machinery research institutions and more than 50 national patents, FTM has established favorable relationship with department of science and technology as well as key universities and colleges.
