Problems solved by technology

In the case of only cast liners, the profile takes care of both the riser and the plate in a single expense, resulting in a heavy individual liner weight
As the cast liner is heavy and has little deflection during a crash, the fixing hardware is also larger in size and takes longer to fix and disassemble
Other than cast steel liners, there is currently no other form of liner in the industry that is capable of initiating effective grinding during bi-directional rotation of the shell

Embodiment Construction

[0030] According to the present invention, disclosed as figure 1 Symmetrically distributed soft rubber backing of the composite lining system shown. The inner wall of the housing of the mill 1 was retrofitted with a rubber-lined composite mill liner 3 . The liner has an upper layer made of cast steel. An example of a liner of the present invention is a layer of chromium molybdenum cast steel combined with a rubber backing layer. Natural rubber may be used to manufacture the rubber layer. These two layers form an integrated system of rubber backing and composite lining. The two layers are bonded together by heat vulcanization during transfer moulding.

[0031] The liner of the present invention does away with the existing thinking of securing the lifting rod to the shell. Instead, the liner of the present invention is a single profile of rod and plate. Thus, independent of any number of holes available in a row, individual profiles can be designed depending only on the n...

Abstract

The invention discloses a composite liner for ball mills comprising an upper layer of alloy cast steel bonded on a symmetrically distributed lower rubber surface, said cast steel layer is prefabricated so as to form the desired profile on the upper surface of the said liner required for specific grinding operations. The present invention also discloses a method of manufacturing composite mill liner.

Description

technical field [0001] The present invention relates to an efficient tool for grinding minerals, stones, and other materials. In particular, the present invention relates to a liner for use in grinding mills in mineral processing operations. More specifically, the present invention relates to a composite steel clad mill lining for AG and SAG mills. Background technique [0002] As mentioned above, grinding mills are typical equipment used in mineral processing. A standard grinder generally has a drum shell connected to a conical / upright mill head with an integral or bolted trunnion, and the assembly is mounted in a On its rotating journal pad bearings. A Self-Autogenous Grinding Mill or SAG is a typical mill, as opposed to a ball mill, that uses steel balls along with the stone feed material as media in the grinding operation to break the stones. The rotating drum continuously throws stones and steel balls in the cataract movement, mainly breaking larger stones through c...
