Description of the case

The draglines are feeding crushers in quarries and cement plants. The buckets are perforated because they are under water. We used the SSAB branded products-"DUROXITE"- 201 (Hardox 450 fabricated weld on LIP SHROUDS - JAW SHROUDS and OUTSIDE BOTTOM HEEL PADS with a multiple-pass complex carbide overlay on a Hardox 450 backing plate.) Our DUROXITE 201 shrouds and heel pads wear min 2X longer than the ESCO/CAT casting shrouds. In Miami where all draglines are feeding crushing plants, our weld on shrouds will reduce the downtime significantly.
