Ball Mill Linings
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 improved ore crushing.
- Blinding of grate plates is virtually eliminated increasing throughput
- Reduced weight compared to steel liners, enabling hand installations: no mill liner handler required
- High-strength designs create less stress and wear on mill bearings, reducing required torque at startup
- Excellent sealing properties to eliminate mineral lock-up
- Reduced noise levels for improved 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 using precise levels of workmanship, facilitating maximum mill uptime for increased production.
Ball mill liner materials in which liners are manufactured include rubber or rubber composite materials to meet your specific dimensions, designs and profiles. Light to medium-sized steel ball mill liners are also available for additional reinforcement.
Multotec’s ball mill liner designs are customisable to your application requirements with the use of our state-of-the-art software, optimising your ball mill machine for efficient performance and increased productivity. Multotec additionally ensures that your ball mill liner can tolerate corrosive levels of acidity and diesel, best serving your application.

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 Plates
Shell plate thickness can vary, which helps in both balancing mill capacity and 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.
Lifter Bars
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 leading edges of these components. With a high-quality attachment system, lifter bars are easy to install on the ball mill liner.
Head Plates
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
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.
Pulp Lifters
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.
Central Cones and Goosenecks
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, enabling easier handling and manageability.
Trunnion and Bell Mouth Liners
Manufactured with a fabricated steel base which is subsequently 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.

Frequently Asked Questions
The balls within the ball mill machine are lifted by side panels in a circular motion in order to be dropped by gravity to crush the desired material. These panels are known as ball mill linings that wear out over time and need to be replaced.
