According to our practical experience, when the new die is installed, first of all, loosen the adjusting bolt of the press roll to adjust the press roll to the state that the outer round surface of the press roll is close to the inner round surface of the ring die; Secondly, adjust the eccentric shaft of the press roller in turn to make the gap between the press roller and the biomass energy wood pellet mill ring die appropriate, pre-tighten the adjusting bolt, pull the pellet press ring die, and gradually adjust the gap, so that the press roller can reach the working state of quasi-rotating non-rotating, and finally tighten the adjusting bolt. When the new mould is installed, it is usually required that the gap between the granulator ring mould and the press roll is slightly larger than what you need, which is conducive to the smooth transition between the fuel pellet machine new ring mould and the old roll. After the new mould and the old roll complete a certain running-in period, the gap can be adjusted to the gap you need.
In use, is to protect the wood straw pellet mill machine ring die and sacrifice the roller, because the price of the ring die is more than ten times or even dozens of times the price of the pelletizier roller, so in use, in the case of reasonable clearance, the hardness of the roller can not be too high, that is to say, the wear resistance of the roller can not be higher than the wear resistance of the ring die.
Finally, the operator in the new installation or replacement of the pellet machine ring die, through the cone assembly of the ring die, the new installation of the die, the requirements to avoid causing the cone and scratch, and the cone and its matching drive flange cone necessary cleaning, oiling assembly. When replacing the pellet making machine ring mold, disassemble, do not touch and scratch the cone surface, coated with oil protection.
For often need to replace the ring die of pellet mill, require regular inspection on the drive wheel rim, prevent the excessive wear and cause mould centering pin fracture, because of excessive wear and tear will influence the ring die and the cooperation between wheel rim, not tight, when the ring die work to mould centering pin shear force caused by fracture, when produce this kind of situation, Do not mistake the strength of the pin for high strength pin, which can only lead to ring die damage and frequent fracture of the safety pin.
Therefore, it is necessary to protect and inspect the matching cone surface of wood alfalfa pellet machine ring die and the matching cone surface of transmission flange regularly. It is also necessary to protect and inspect the assembly surface and its matching components for hoop assembled ring dies. When the press roller used for a period of time, there will be wear phenomenon, affecting the precision of the ring die, thus affecting the production output of the ring die, it should be necessary to repair or replace a wood palm pellet machine new ring die.
