The Arrangement Of The Mold Holes Of The Wood Chip Pellet Mill?

                The ring die of biomass fuel pellet machine is a porous ring piece with poor working conditions. It is subjected to cyclic extrusion and material friction of the pressure roller for a long time, which produces cyclic bending stress and contact compressive stress. Its main form of damage is fatigue damage.

                The structural parameters affecting the fatigue failure of the ring die mainly include the hole diameter, length-to-diameter ratio, die hole arrangement and the number of holes. The arrangement of the ring die hole structure has an important influence on the overall strength of the ring die, material extrusion pressure, particle molding quality and pelleting energy consumption. The arrangement of the die holes of the biomass fuel pellet mill is an important factor in the design of the ring die. The size of pellets also varies according to different pelletizing objects.
