Ball Mill Linings

 

Ball Mill Linings from Multotec provide optimum wear lining solutions for the toughest applications, ensuring optimum grinding and crushing efficiency.

  • Blinding of grate plates is virtually eliminated
  • Reduced weight compared to steel liners
  • Less wear on bearings and reduced torque at start up
  • Excellent sealing properties to eliminate gold lock-up
  • Reduce noise levels for improved working conditions

Our Ball Mill Lining designs are manufactured with rubber or rubber composite materials to meet your specific requirements. Light to medium sized Steel Liners is also available for additional reinforcement.

Multotec’s Ball Mill Liner designs are customisable to your application with the use of our state-of-the-art software, optimising your ball mill machine for efficient performance and increased productivity.

Get to know our Ball Mill Liner Design

Maximise the lifespan and performance of your ball mill machine, with a selection of rubber or rubber composite liners with available steel reinforcements.

Refined through our ongoing Ball Mill design improvements, Multotec’s Ball Mill Liners maximise uptime and service intervals while providing increased process productivity and efficiency to crush the ore.

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 a variety of different rubber formulations and attachment system materials.

With these types of Ball Mill formulations and accessories, Multotec can ensure that your liner will withstand materials with corrosive levels of acidity or diesel.

Multotec offers 3 different design categories that either match customer, OEM, or best practise rules. Our Ball Mill Liners can also be designed to meet any customer requirement or to improve mill efficiency.

MultoMet Components:

Our Ball Mill solutions can be fitted with MultoMet composite Lifter Bars, Shell Plates, and Head Plates to further suit your needs. The MultoMet range utilises Hardox 500 wear-resistant steel, attached to the leading edges of the Lifter Bar array, and is embedded within Shell Plates and Head Plates, ensuring maximum abrasion and impact resistance.

Shell Plates

Shell plate thickness can vary, which helps balance mill capacity and extend liner life. For arduous milling applications, or where drilling patterns produce shell plates that are too wide and are thus exposed to high wear, Multotec’s Shell Plates with Hardox strips can be utilised.

Lifter Bars

Available in a range of profiles and dimensions, Multotec’s 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, our Lifter Bars are easy to install.

Grate Plates

Our 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 a built-in Hardox wear resistant matrix. Our Composite Grate Plate has outperformed a steel grate plate equivalent.

Pulp Lifters

Our design comprises a steel core structure and is covered with a high-density rubber lining. The thickness of the rubber lining is dependent on application. Our Pulp Lifters are designed to ensure the correct volumetric flow of pulp while preventing carry-back.

Central Cones and Goosenecks

These components assist in the controlled discharge of the material, maintaining mill capacity across the operation. Central Cones are provided in segments, which are then assembled inside the mill. This enables easier handling and manageability.

Trunnion and Bell Mouth Liners

Our Trunnion and Bell Mouth Liners are manufactured with a steel base that is then rubber lined. These light to medium sized Steel Liners from Multotec are also available for use 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.

Research & Development at Multotec

The continuous commitment to improve our services and design has resulted in the development of our Ball Mill Liners that delay shutdown and maintenance periods whilst offering improve grind efficiency.

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 machine.

Multotec’s installation expertise is based on over 45 years of experience. We ensure that your ball mill liners are fitted with precise levels of workmanship, facilitating maximum ball mill machine uptime for improved production levels.

Frequently Asked Questions

1. What is a ball mill used for?

Ball mill machines are ideally used for crushing and grinding materials into an extremely fine form or powder. Ball mills are used in mineral processing and pharmaceutical applications.

2. How does a ball mill work?

Ball mill grinders work on the principle of impact and attrition. The ball mill machine contains a hollow cylindrical shell that rotates around its axis, becoming a tumbling ball mill. The impact of the balls that drop from the top of the shell therefore reduce the size of the material at the bottom of the shell. The balls within the ball mill machine are made of stainless steel or rubber to move and crush the material contained within it, therefore acting as grinding mill balls.

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.

3. What is the ball mill method?

High energy ball milling is a grinding method that breaks down materials into extremely fine powders. The collision between balls in a concealed container generates localised high pressure to crush the desired material.

4. What is the liner in a ball mill?

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.

5. What are ball mill liners made of?

Ball mill liners are available in rubber or rubber composite materials that is alloyed casted in steel or wear resistant cast iron.
