Precision Heavy Duty Mill Relining Machine MRM Hydraulic Control Mill Liner Handler

The MRM Mill Liner Handler is a specialized hydraulic liner handling machine designed for modern mining and mineral processing operations. It is primarily used for liner replacement and maintenance on ball mills, SAG mills, and AG mills.

By replacing high-risk manual work with full hydraulic mechanical operation, the machine enables automatic gripping, transporting, precise positioning, and installation/removal of mill liners. It effectively shortens mill downtime, reduces on-site safety risks, and improves overall maintenance efficiency and installation accuracy.

It is a core piece of equipment for large concentrators seeking standardized, safer, and more efficient mill maintenance.

Traditional mill liner replacement relies heavily on manual work combined with lifting operations. It faces four major problems:

Confined and narrow working space: difficult access and limited movement for personnel

Dusty and harsh environment: low visibility and high health risks

Heavy liner handling: frequent misalignment, poor fit, and bolt hole mismatch

High safety risk: crushing, impact, and fall hazards

At the same time, manual liner replacement has unpredictable schedules and long downtime, directly reducing mine output, increasing maintenance costs, and damaging production efficiency.

The MRM Mill Liner Handler replaces manual operation with hydraulic mechanical handling:

1.Greatly reduces the number of personnel entering the mill

2.Eliminates safety hazards at the source

3.Keeps liner replacement schedules under control

4.Helps mining companies significantly reduce downtime losses and maintenance risks

The machine operates fully mechanically. No personnel are required to enter the mill to carry or lift heavy liners. This greatly reduces confined-space, high-risk operations and effectively prevents crushing, falling, and liner impact accidents, raising the safety standard of mine maintenance.

Compared with traditional manual liner replacement, the machine offers faster installation and more efficient positioning. It significantly reduces mill downtime, increases mill availability and ore throughput, reduces economic losses caused by production stoppage, and helps mines cut costs and improve efficiency.

Equipped with a precision multi-axis hydraulic linkage system, the machine supports lifting, extending, rotating, and fine adjustment from multiple angles. It runs smoothly and positions accurately, ensuring tight liner fit and standard bolt hole alignment. This improves mill assembly quality and operating stability while extending equipment service life.

The entire machine is made of thickened, high-strength steel with integrated welding. It has undergone multiple load tests and stress reinforcement, offering strong impact resistance, wear resistance, and load capacity. It can operate stably over the long term in high-dust, high-load, and high-intensity continuous mining environments, with low failure rates, strong durability, and easy maintenance.

It can adapt to most ball mills, SAG mills, and AG mills on the market. Customization is available based on mill inner diameter, shell structure, liner weight, and on-site working conditions. It is suitable for maintenance upgrades and retrofits of both new and existing mineral processing lines.

Widely used in gold, copper, iron, lead-zinc, molybdenum, and non-metallic mineral processing plants.

Suitable for ball mills, SAG mills, and AG mills in:

1.Routine liner replacement

2.Periodic shutdown maintenance

3.Annual overhaul

4.Upgrades and retrofits of older production lines

It meets the standardized, regulated, and safe maintenance needs of medium and large mining operations.
