When grinding mills age, the location of the liner bolt nuts in the shell can become worn. This can cause slurry leakage. Slurry leakage is a real problem. It cuts through the shell and makes the leak grow and grow: a vicious cycle. Using our Pitbull™ Torque Liner Washer can mitigate any more damage from happening until there can be a complete repair of the hole created by a bolt boring around.
Our Pitbull™ Torque Liner Washer grips and holds like no other washer can. This sealing washer with teeth is one of our most popular washers because it holds like a “pitbull’s bite”, and provides that stable platform needed in worn areas. In addition, for bolt diameters of 1 ¼”, 1 ½”, 2″ (M48 and M52), we even have an Oversized Pitbull™ made to cover a badly worn bolt hole area, on the shell.
Our newest creation, in this respect, is a Double Sided Pitbull™ Liner Washer. This washer with teeth was developed because, often times, a liner bolt is not initially manufactured long enough to allow for both the Pitbull™ Torque Liner Washer and the Two Piece Sealing System to fit. Then, when an enlarged shell hole occurs as the mill ages, and needs a Pitbull™, the liner bolt must be replaced with a new, longer bolt to accommodate both systems. Now there is another option. The Double Sided Pitbull™ is the solution to accommodate both systems without requiring an entirely new, longer bolt.
