1. Transverse crack of rod body. Excessive moisture of raw material is easy to cause transverse crack on rod body.
2. Causes of longitudinal cracks in rod body: A. Excessive temperature. B. Excessive screw inclination Angle; C. Abrasives are damaged. Solutions to longitudinal cracks: A. Reduce temperature; B. Repair the dip Angle as perpendicular to the axis direction as possible; C. Replace or repair.
3. Reasons for too small rod density: A. High temperature; B. Low screw pressure. The heating temperature is too high or too low, the forming sleeve is badly worn, the propeller Angle is not consistent, the raw material is too wet. Solutions to low rod density: A. Cooling; B. Reduce the thread lift Angle and increase the screw pressure.
4, the rod center density is small, or there are scattered sawdust reasons: propeller shaft tip diameter wear, to repair welding and thickening. Shaft tip deviation can also cause the above problems, it needs to be corrected at high temperature.
5, the biomass briquette machine anti-gas: the performance in the production from the feed outlet to the outside of the gas, mainly because of the lack of feed. Also may be due to the raw material moisture, heating temperature is not enough.
6, straw charcoal making machine "stuffy car" : the raw materials mixed with large particles and hard impurities. Low voltage or low heating temperature, or may not be raw materials, the former need to shut down, remove impurities. The latter should continue to warm to soften the raw material, or re-drying.
7. Reasons for firing of the biomass briquette machine for sale: A. Too damp material; B. Stick a dead eye. Improper temperature control, excessive moisture in raw materials, propeller wear, shaft tip is not straight, vent plug, propeller head spiral is too large or too small, sleeve wear serious. Encounter this kind of circumstance to want to compare one by one according to afore-mentioned reasons, make adjustment accordingly after finding out the reason. A. Adjust the drying temperature and dry the materials; B. The solution of seeing the stick and the dead eye.
8. Reason for bar bending: uneven heating and excessive moisture in raw materials. Solution to bar bending: raise the temperature.
9. Cause of flower rod: A. Screw is not repaired; B. Mold wear; C. Low lignin of raw materials. The solution of flower rod: A. Reduce the thread raising Angle and increase the screw pressure; B. Replace or repair; C. Add heavy raw materials, or replace the raw materials until they are fermented for one or two months before use.
