Maximise the lifespan and performance of your mill, with a selection of rubber and rubber composite liners available.
Refined through ongoing design improvements, our liners maximise uptime and service intervals while providing an improved crushing of the ore.
These 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 liner can tolerate corrosive levels of acidity and diesel.
Our 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 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, which is found along the leading’s edges of these components. With a high-quality attachment system, lifter bars are easy to install.
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 the correct volumetric flow of the pulp. Rubber wear plates are designed to be bolted onto the high-wear areas of the liner to 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 mill and scrubber, enabling a clean, smooth lining across the liner.
Our commitment to ongoing design improvements and high service offerings has resulted in the development of ball mill liners that extended periods between shutdowns and improve grind efficiency.
Our 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 machine.
We ensure that your liners are fitted with precise levels of workmanship, facilitating maximum mill uptime for increased production.
Multotec’s expert installation and fitment is based on over 45 years of experience.
Ball mill machines are ideally used for crushing and grinding materials into an extremely fine form or powder.
Ball mill grinders work on the principle of impact and attrition, where impact creates size reduction as the balls drop from the top of the shell.
It contains a hollow cylindrical shell that rotates around its axis. This shell is filled with balls that are made of stainless steel or rubber – which move and crush to the material contained within it.
High energy ball milling is a grinding method that breaks down materials into extremely fine powders. The collision between balls in a concealed container will generate localised high pressure.
The role of a liner is to give the mill head protection against wear and tear, thus increasing their lifetime and creating optimal grinding efficiency.
Liners can be made of rubber, alloyed cast steel or wear resistant cast iron.
