The provence of Hidalgo in Mexico has a large cement plant with a ball mill that had developed cracks through both sides of the trunnion. ECRS/Metalock was brought in to install our Metalace and Mini-Keylock mechanical repair components along the crack to seal and hold pressure against the journal bearing. Two work locations were used with one crew inside the trunnion and the other on the outside. The crack repair was laid out and the components installed. Once completed the repair was then brought back to a machined finish on the working surface of the trunnion end.
