螺旋绞刀是挤泥机的主要磨损部件。尤其是绞刀叶片的推力面和刃部磨损极快。因此,绞刀需频繁更换和修理,既误工,又增加修理成本。我们通过长期的试验,进行不断地改进和革新,利用废旧材料,科学地对螺旋绞刀进行修补和耐磨处理,取得了较好的使用效果与经济效益。具体的修理和处理 Screw cutter is the main wear parts of the mud mill. Especially the cutter blade thrust surface and blade wear extremely fast. Therefore, reamer need frequent replacement and repair, not only work, but also increase the cost of repair. Through long-term tests, we constantly improve and innovate, use scrap materials and scientifically repair and wear-resisting spiral knives, and achieve good results and economic benefits.
