FAST, EASY, SAFE RELINING
Whether your grinding mill is large ball, semi-autogenous or autogenous, PaR Systems mill liner handlers will reline your mill faster, easier, and safer.
PaR offers a range of mill liner handlers to fit your application; the MLH-120 is designed for 36-inch trunnion openings and loads up to 2,000 pounds, the MLH-130 works with 24-inch openings and loads up to 1,000 pounds, and the MLH-320 lifts any shape and weight of liner up to 5,000 pounds. PaR liner handlers are available with full 8-axis liner handling up to 10,000 pounds.
Typically, the handler's boom and operator seat are mounted on a powered trolley, allowing the boom to be positioned perpendicular to the mill. The hydraulic grapple lifts, tilts, and orients a liner for aligning and bolting into position.
PaR Mill liner handlers are delivered fully assembled and operational ready to be positioned to the mill trunion opening. As old liners are freed from the mill, they are hydraulically lifted and placed on the handler's roller conveyor. The conveyor transfers old liners outside and brings new liners inside.
The operator usually relines two or three rows below the horizontal and above the charge level before inching the mill to the next two or three rows to be relined. The knuckled boom and 360-degree boom rotation make it easy to reline both sides of the mill before inching the mill to the next few rows to be relined.
