Background
Our Canada customer sends normal manganese jaw plates to his Nicaragua customer. its span life 7 days for fixed jaw plate,14 days for movable jaw plate. However, Nicaragua customers need more wear parts.
Challenges
We designed a set of TIC insert jaw plates that featured titanium carbide (TiC)inserts in the high wear areas of the manganese alloy jaws. Upon analysis, the fixed jaw showed wear in areas without TiC inserts, indicating that the highly abrasive material made contact with the entire surface of the plate. The movable jaw also showed excessive wear in the wedge.
Our engineers decided on TiC inserts throughout the entire impact surface of the 2 jaws to further increase wear life. The addition of a full length curved plate in the movable jaw further increased wear life.
Performance & Results
The final design of the fixed jaw plate solved a critical wear issue for Nicaragua customers. Our customer certified the wear life of the TIC inserts jaws operated for 726 hours or just over 30 days of 24-hour continuous operation. This dramatic improvement of over 8.57 times the wear life of the original manganese jaws was met with extreme satisfaction. The engineers expressed confidence in the movable jaw and do not feel the need to test its wear life as they “expect exceptional functioning knowing the performance of the fixed jaw”.
