Ball Mill Liners
Ball mill liners from Multotec maximise the lifespan and performance of your ball mill, with a selection of rubber and rubber composite liners available. Refined through ongoing design improvements, our ball mill liners maximise uptime and service intervals while providing an improved crushing of the ore.
Features of our ball mill liners
- Low-weight, high-strength designs create less stress on mill bearings and reduced torque requirements
- Excellent sealing properties eliminate mineral lock-up, improving the recovery of valuable products
- Blinding of grate plates is virtually eliminated, increasing throughput
- Low liner weight enables safe installation by hand. No mill liner handler required!
- Low noise levels enhance working conditions

Our ball mill liners are the result of state-of-the-art software-driven designs with industry-leading inspection data, achieving an optimal charge trajectory and rate of wear life for your ball mill. We ensure your ball mill liners are fitted with precise levels of workmanship, facilitating maximum mill uptime for increased production.
Our ball mill liners are available in a wide range of dimensions, designs and profiles. They can be tailored to the specific application requirements of your mineral processing operation, with different rubber formulations and attachment system materials available. With these options, Multotec ensures your ball mill liner can tolerate corrosive levels of acidity and diesel.
Ball Mill Liner components
Our ball mill liners solutions can be fitted with MultoMet composite lifter bars, shell plates and head plates. The MultoMet range utilises Hardox 500 wear-resistant steel, attached to the leading edges of the lifter bar array and embedded within shell plates and head plates, ensuring maximum abrasion and impact resistance.
Shell plate thickness can vary, which helps both in balancing mill capacity as well as extending ball mill liner life. For arduous milling applications, or where drilling patterns produce shell plates that are too wide, thus exposed to high wear, shell plates with Hardox strips can be utilised.
Available in a range of profiles and dimensions, lifter bars increase the efficiency of the milling operation by maximising the agitation of the ore. The impact and abrasion resistance of these bars is maximised by Hardox 500 steel along the leadings edges of these components. With a high-quality attachment system, lifter bars are easy to install to the ball mill liner.
We custom-design head plates according to each ball mill to ensure maximum performance and lifespan. Most commonly, our head plates are built from high-quality, specially-formulated rubber. In arduous ball mill applications, Hardox strips can be fitted to the head plates to increase their operational life.
Grate plates are available in a range of aperture sizes and configurations. Internal frames are designed for different mill loads, and it is possible to use semi-overflow designs in order to control the pulp level in the mill. Different options for extending plate life exist as required by your application, such as built-in MultoMet lifter bars.
Manufactured with a rubber-lined fabricated steel base, our pulp lifters use high-quality designs that ensure a correct volumetric flow of the pulp. Rubber wear plates designed to be bolted onto the high-wear areas of the ball mill liner improve the performance life of your mill.
These components assist in the controlled discharge of the material, maintaining mill capacity across the operation. Cones are provided in segments, which are then assembled inside the mill. This enables easier handling and manageability.
Trunnion and Bell Mouth Liners
Manufactured with a fabricated steel base that is then rubber lined. Loose steel-reinforced rubber liners are also used in larger trunnions.
Filling and Support Segments
Extend the wear liner to the corners of your ball mill and scrubber, enabling a clean, smooth lining across the ball mill liner.
