Feed machinery in the production process, the material requirements for the processing of the necessary clean-up, avoid mixed with chunks of gravel, sand, iron, bolts and iron and other inclusions of hard particles wear ring die, if a large number of large hard Inclusion will likely result in a ring die many times by force, to produce fatigue, when a second force exceeds its specified ultimate strength, burst mode phenomenon will appear.
In addition, the operator at the time of the newly installed or replaced ring die of the pellet machine, if you installed a new cone assembly through a ring mold, to prevent bumps and scratches cone, and the necessary clean up its rim with the drive cone to oiled assembly needs to be replaced, not bumps and scratches after the demolition of the cone, and oiled protection. Often need to replace the ring die particles machine, between the ring die and the rim should be checked regularly drive rim, avoid excessive wear and tear caused by breaking the mold centering pin, after excessive wear will affect with, if the fit is not tight, easy to mold centering pin shear forces caused by the ring mold work breaks, when this happens, do not blindly think that this is enough and replaced the strength of the pin high strength pin, so that can only ultimately lead to the ring die damage and safety pins regular breaks.
Therefore, the ring die of the pellet machine with the cone and mating cone gear rim protection and regular maintenance check is essential. If the hoop-style assembly of the ring mold, its protection and check the mounting surface and mating element is also necessary, there will be a period of time after the press roller wear, and then with precision the impact of the ring mold and the corresponding small particles feed processing unit of production output, they should carry out the necessary repairs or replacement of the ring mold.
