1. the use of grooved rollers, material while squeezing bias on both sides. Different materials should be using different roller shell.
2. the roller surface not in place. This is why manufacturers, it is best to return repaired, it would accelerate wear.
3. use a ring mold there is no taper to suppress. Ring mould taper repression can ensure the smooth material extrusion.
Second, biomass pellet mill rollers in the bearing life is too short.
1. bearing their own reasons. Rollers must be used very good bearing, such as Harbin and Luoyang.
2. no quantitative adding grease to the roller on a regular basis. Only after sufficient lubrication of roller bearings can achieve the ideal State, Henan sanli machine is automatic lubrication grease system, effective solution to the operator because of laziness and lack of timely biomass pellet feeder sticks bearing lubrication problems.
3. Add roller grease quality is too poor. Qualified assured grease should be used.
4. roll the ends of the seal wear. Replacement of the sealing cover.
5. the eccentric shaft cannot be turned. Fixed multi-roller front panel bolts are not released, it should release the pressure roller device; administration another reason is because long time no open roller, rollers plate and spindle front rusted, so increasing friction, which is the application of waste engine-oil lubrication, turn to try again. Third, the particle size is too large.
Material should be too high causing biomass Pellet Press Club, wear large. Recommended 1-5 mm of raw materials.
