Abstract
A mill liner element is structured with an elongated elastomer member having a non-elastomeric backing plate and a plurality of non-elastomeric inserts formed into the elastomer member to provide a liner element that provides a lifter bar element and a wear element that is less prone to cracking compared to conventional all-metal mill lining elements, and which provides ease of handling and replacement when worn. A multiplicity of mill liner elements are positionable in a grinding mill shell, and are suitable for use in a variety of types of grinding mill structures, including ball mills and AG and SAG mills.
Claims14
A mill liner element, comprising;
- an elongated elastomer liner member having a base surface for positioning along the inner wall of a grinding mill shell;
- a non-elastomeric base plate member positioned along said base surface of said elongated elastomer liner member;
- a plurality of non-elastomeric inserts embedded in said elongated elastomer liner member;
- and
- wherein, said elongated liner member has a first section that extends a length of the elongated liner member and has a height, and said elongated liner member has a second section that extends a length of the elongated liner member, said second section having a height which is greater than said height of said first section.
A grinding mill, comprising:
- a mill shell having a continuous cylindrical wall encircling a rotational axis;
- a plurality of mill liner elements positioned adjacent each other along said wall of said mill shell, each said mill liner further comprising,
- an elongated elastomer liner member having a base surface for positioning along and inner surface of the wall of said mill shell;
- a non-elastomeric backing plate member formed in said base surface of said elongated elastomer liner member;
- a plurality of non-elastomeric inserts embedded in said elongated elastomer liner member;
- and
- wherein, said elongated liner member has a first section that extends a length of the elongated liner member and has a height, and said elongated liner member has a second section that extends a length of the elongated liner member, said second section having a height which is greater than said height of said first section.
