Hydraulic Driven Ball SAG Mill Relining Machine Mill Liner Replacement Manipulator

MRM Mill Reline Machine – Liner Handling Manipulator for Ball & SAG Mills

Product Overview

The Mill Liner Replacement Manipulator is a specialized maintenance device developed for liner dismantling and installation operations inside ball mills and SAG mills at mining concentrators. The equipment assists in completing the full sequence of gripping, transferring, positioning, removing, and installing mill liners, effectively replacing the traditional method of manual work combined with simple lifting rigs. It reduces direct manual involvement and improves the high-risk working conditions inside the confined space of the mill shell.

The machine is hydraulically driven, with a manipulator arm capable of telescopic, rotational, and pitching motions in multiple dimensions. Equipped with dedicated gripping tooling, it can accommodate mill liners of different sizes and weights. The unit is radio remote controlled, allowing operators to control the equipment from a relatively safe position and reducing the need for personnel to be directly exposed to hazardous areas inside the mill shell.

Core Advantages

Full-Process Assistance — Supports the complete liner removal and installation workflow, reducing on-site labor input, helping shorten mill shutdown duration, and safeguarding continuous production.

Radio Remote Control — Operators stay away from high-risk areas inside the mill shell, improving the on-site working environment and reducing safety risks during operation.

Multi-Degree-of-Freedom Manipulator Arm — Flexible telescopic, rotational, and pitching motions enable liner posture adjustment and precise positioning within the confined space inside the mill.

Smooth Hydraulic Transmission — Stable power output with overload and limit protection, suitable for heavy-load, dusty operating environments at mining sites.

Customizable to Working Conditions — Load capacity, arm length, and gripping tooling can be matched to different models of ball mills and SAG mills.

Complete Technical Support — Operation guidance and daily maintenance documentation provided for easy on-site use and servicing.

Structural Features

The equipment features a modular structural design. Structural components undergo multiple processes including blanking, welding, flaw detection, and machining, ensuring stable overall operation. The hydraulic and electrical control systems are equipped with multiple protection mechanisms, including limit and overload protection, reducing risks caused by equipment faults during operation.

Adaptable adjustments can be made according to customer mill specifications, shell inner diameter, individual liner weight, and on-site working conditions to meet the liner replacement needs of different mining projects.

Applications

Widely used in various metal ore dressing mines, suitable for different specifications of ball mills and SAG mills. Applied in liner removal and liner installation operations during routine mill maintenance. Can be combined with hydraulic bolt breakers and other liner replacement tools to form a complete mill liner replacement solution.
