What to do if fatigue cracks appear on the blades of the wood crusher

We all know that the blade of a Sawdust Machine is its core accessory, because when the wood crusher works, it mainly relies on the blade to slice and crush the raw materials. Without the blade, these tasks will not be carried out, so the blade is usually maintained. Sometimes, we need to check the degree of wear. If the wear is serious, we need to replace the blade with a new one. However, there is another situation where fatigue cracks will appear on the blade. This fatigue crack is different from wear, so if this problem occurs, it is still possible. Solved, no need to replace new blades.

Once fatigue cracks appear on the blade of the Wood Dust Making Machine, we must first observe what type of fatigue crack it is. Fatigue cracks are generally divided into two types, one is perpendicular to the blade surface, and the other is parallel to the blade surface. Fatigue cracks perpendicular to the surface are mainly caused by thermal fatigue effects. At this time, the wood flour machine needs to be filled with coolant to reduce the heat generated by the blade during cutting.

If there are parallel fatigue cracks, this situation is mostly due to insufficient toughness and hardness of the blade, or the hardness of the raw material is too hard. If this happens, pay attention to avoid overly hard raw materials when feeding the wood crusher. Put it into the machine.
