Sawdust particles machine mould quality not only mould don't wear this one disadvantage, mould easily burst mode, change the frequency increase, increase the intensity of labor, so choose qualified sawdust particles machine mold, is to increase the production efficiency, cost saving is the most effective way.
Sawdust particles machine ring die are usually made of carbon steel or stainless steel material by forging, cutting, drilling, such as heat treatment process is made.
A, materials used in the ring die and each processing procedure for its using life and granulating quality, output has a direct impact.
Therefore, when the choose and buy ring die, must choose superior skills, some have planning manufacturers. If small plant of optional choose skills, poor equipment, will appear in the process of producing this or that questions (for example loop die not discharging, commodity grain surface is rough, detonation mode, etc.). Secondly, die grinding is also very important, the small manufacturer skills constraints due to equipment, mainly by manual polishing, often appear behind appearances, leakage may not meet the requirements of finish. Therefore the ring die, will not be in the actual production process, even if the material, will constitute a rough surface particles and machine surface. So users should be in the straw quality of ring die pellet machine, the better off.
Right to choose the suitable thickness of mould is to ensure the quality and output of an important link, it involves a question of compression ratio (compression ratio = die useful length/die hole diameter). Compression ratio of ring die, its form grain density is big, the surface is bright and clean. Otherwise, particle appearance from the lax, straw particle high powder content. If the compression ratio is too big, can make ring die hard to discharge, so that the die hole plug. To produce fiber material than high, ring die compression ratio should be relatively small, or use the old mould produce.
If press roller and the ring die gap adjustment is reasonable, directly affect the sawdust pellet machine operation condition. Spacing is too large, because the ring die and roller pressure between the extrusion pressure is not enough to overcome the friction material through the die and cause clogging. The small ring die and roller is easy to damage. So if you want to grasp the reasonable spacing, need to rely on grain work after a long time production practice and explore to make the correct adjustment. Here are some ring die and roller to adapt to experience and share, namely the new roller is matched by a new mould, a pair of roller fixed using a ring die cooperation. In this way, can avoid the mold with old roller, perhaps the old mould with the new roller surface, so as not to cause new roller or new mould wear and tear. Indirect progress and extension ring mold, the use of the roller life and reduce the cost of production.
A ring die use effect is good or bad, in addition to their own technological quality resolution, certainly cannot leave the ring die protection. Because in the process of produce, to have a ring die block, wear phenomenon, so the ring die, if you are not necessary protection protection, necessarily constitute output drop, increase of energy consumption, and not discharging, rendering machine. Therefore, there is the surface occurs, it is necessary to ring die the protection of a series of operations.
Sawdust particles forming die and roller skin to make sacrifices, because sawdust particles molding difficult, must have a powerful force to make particles forming, so inevitably cause mould wear and tear. Based on past experience, we do not support manufacturer for mold repair. Because the repair mold, is nothing but increase the taper hole. But also can cause the quenching hardness in repair damaged, that within a very short time after repair will wear into the flour extraction rate is high, not forming, small density, low temperature of the state. Costs of repair will justify the cost of producing negative is the problem we need to carefully consider. So manufacturers, in the case of a mold damage, it is best to add the new mold, in order to avoid problems in the subsequent production.
