Pitbull™ Liner Washer

The Pitbull™ Liner Washer is designed with special teeth to span and grip enlarged shell holes. The neoprene seal is on the outside of the teeth, so that it does not interfere with joint efficiency. We designed the Pitbull™ sealing washer to complement the extended surface area provided by the Ridgeback™ Liner Bolts.

VFB pitbull-34036When Grinding Mills age, the location in the shell for liner bolt nuts 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 viscous cycle. By using our Pitbull™, this can mitigate any more damage from happening until there can be a complete repair of the hole created from a bolt boring around.

Our Pitbull™ Liner Washer grips and holds like no other washer can. The Pitbull™ Liner Washer is one of our most popular washers because they hold 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 was developed because, often times, a liner bolt is not initially manufactured long enough to allow for both the Pitbull™ 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.
