Mill and Scrubber Linings

Multotec mill and scrubber linings are specially designed to increase efficiency, reduce downtime and lower the overall costs of your milling plant.

With a complete range of mill liner components, from lifter bars and shell plates to centre cones and trunnion liners, we use a range of engineering tools including MillTraj modelling software, Inventor 3D and AutoCAD to develop customised mill and scrubber liners to your requirements.

As your specialist in rubber wear linings, Multotec offers full plant audits, installation and maintenance and condition monitoring services for your grinding mill liners.

  • Reduced weight means less wear on bearings; reduced torque requirement at start up; and improved installation safety
  • Excellent sealing properties eliminates particle lock-up
  • Throughput is increased as blinding of grate plates is virtually eliminated
  • Reduced noise levels improves working conditions
  • Real-time MultoScan condition monitoring accurately predicts liner life to maintain constant efficiency
  • Milling circuit audits and analysis are available to optimise your production

Our Mill & Scrubber Components

Test Work Capabilities

Shell Plates

The thickness can vary in order to balance mill capacity and liner life. The width is designed for optimum protection from the lifter bars. MultoMet™ shell plates, incorporating Hardox strips, are for demanding applications or where the drilling                                                                          pattern result in the shell plates being                                                                                          exposed to high wear.


Lifter Bars

Lifter bars are available in a range of widths, heights, and in rubber or composite profiles. Steel reinforced lifter bars are designed to provide maximum impact and abrasion resistance. MultoMet™ lifter bars have Hardox tempered plates whilst heavy-duty                                                                                  MultoMet™ lifter bars have castings for larger ball                                                                      mills and SAG mills. 


Spiral Concentrators

Head Plates

Head Plates are custom designed for each mill or scrubber for ease of installation and handling. Rubber head plates are available in various designs to combat sliding abrasion. Head plates are designed to provide easy installation and handling.                                                                                    MultoMet™ head plates, incorporating Hardox                                                                            strips, are designed for gruelling applications.


Mill Liners

Grate Plates

Heavy-duty grate plate designs are available for larger mills with a range of aperture sizes. The elastic property of rubber allows for smaller slots than steel grates whilst eliminating blinding problems. Internal frames are designed for different mill loads and                                                                          semi-overflow designs control the pulp level in the                                                                      mill.


Magnetic Separation

Pulp Lifters

Manufactured from a fabricated steel base, which is then rubber lined, Multotec’s pulp lifters ensure the correct volumetric flow. Rubber lined pulp lifters provide optimum discharge of pulp through the mill in order to minimise ‘bottle-necks’. Rubber wear plates,                                                                  bolted onto the high wear areas, achieve an                                                                                improved life.

Filter Press

Trunnion & Bell Mouth Liners

Trunnion liners feature a rubber-lined fabricated steel base, which is then rubber lined. Loose steel-backed rubber liners are also used in larger trunnion and bell mouth linings.


Filter Press

Centre Cones

Central cones are designed to assist the discharge of the material to increase capacity. These are supplied in segments that are assembled inside the mill for ease of installation. The centre cone section should be directly underneath the pulp lifters section.

Filter Press

Filling & Corner Segments

Filling, support and corner segments fit into the corners of the mills and scrubbers to provide a clean interface between the head and shell liners. Multotec’s design locks the head plates and grate plates into position and stop material collecting in the                                                                  corners of your mill.

Multotec is your turnkey specialist in rubber mill linings for Scrubber, Ball, SAG and AG Mills.

Rubber developed for your requirements

Multotec’s rubber mill and scrubber linings are designed by combining the results of computer simulations and inspection data in order to optimise charge trajectory and wear life.  Multotec can provide the correct rubber formulation and attachment systems such as stainless steel T-tracks to suit highly acidic, high pH and even diesel operating environments.

Mill/Scrubber Linings versus Steel:

  • Longer life due to less wear results in substantial cost savings.
  • Lower product weight reduces downtime during installation and replacement, improving production while eliminating the need for a liner handler.
  • Resilient material enables easy and safe installation as well as trouble free handling which reduces risk of injuries.
  • Excellent sealing properties that reduce the risk of flushing behind lining and minimise gold lock up.
  • Reduced blinding of Grate Plates resulting in increased throughput.

Our lining components are available in a wide range of designs, dimensions and profiles. In addition to the standard rubber components, we also supply MultoMet composite lifter bars, shell plates and head plates.

Multotec installation teams supervise, assist and undertake complete lining installations. Stock control assistance and condition monitoring are also provided.

Mill Trajectory Modelling

Multotec utilises MillTraj software to analyse wear requirements to ensure customised mill liner profile designs that consistently deliver an optimum trajectory of material in your milling plant.

This specialised trajectory modelling measures the variable speed to demonstrate the impact of mill speed. The display features all representative wear resistant liners and mill charge with a clear Perspex screen on either side in order to assess the trajectory pattern of mill charge during operation.

Our mill trajectory modelling

  • Informs selection of lifter angles and heights related to: mill application, mill size, mill speed, filling and ball size
  • Assesses current comminution circuit parameters
  • Monitors the condition of comminution and other equipment
  • Indicates design improvements
  • Is simple to use, with known mill parameters

Mill Liner Design

Multotec uses computer simulation to provide optimum liner configuration that extends liner life and increases mill productivity.

hydraulic separation is achieved via a hydrocyclone sand separator, a water cyclone separator or cyclonic sand separator

Hydrocyclone manufacturers manufacture hydro cyclones as well as the dewatering cyclone and classification cyclone

Track liner wear in real time with Multoscan

Achieving the desired grind efficiency in mills is a critical focus for mines seeking to optimise the operating costs of their mineral processing operations.

As gradual wear on the mill liner profile affects the material trajectory inside the mill, resulting in decreased impact grinding or attrition grinding efficiency, operators need to ensure an optimum wear mill liner profile is constantly maintained.

Introducing MultoScan: the most affordable mill liner profile condition monitoring system. Where traditional mill liner monitoring and inspection is unreliable and time-consuming, MultoScan accurately tracks your milling plant’s liner wear in real time and notifies you when it begins to reduce efficiency.
