What is the fuel pellet machine prone to?

                 In the straw pellet machine molding process, the problem of problems stopping production in the middle of the problem analysis, the bending of the rod: raw material moisture is too large. Anti-gas: manifested in the production of gas sprayed outward from the mouth of the lower material, mainly due to insufficient material supply. It is mainly due to insufficient material supply. It may also be due to excessive moisture in the raw material and insufficient heating temperature. Bright surface: the section of the bar has a bright light, although the density is good, but the hardness is not good. This is the first spiral at the beginning of the first channel is too steep, it should be smoothed.

                The center of the rod is less dense, or contains scattered sawdust: this is due to the wear of the root diameter of the propeller shaft tip, to be welded and thickened. The incorrect tip of the shaft can also lead to the above problems and should be corrected at high temperature. Surface cracks: too much moisture in the raw material is likely to cause transverse cracks on the bar, too little moisture is more likely to lead to the emergence of longitudinal cracks. In addition, too high a heating temperature will cause excessive softening of the raw material, thus causing insufficient material supply. This will also lead to cracks. The general solution to insufficient material supply is to appropriately increase the diameter of the spiral, or grind the spiral wall, increase the pitch between the spiral.
