Continuous improvement

A mill lining is a customized wear part. Identifying the appropriate type of lining and design is vital for optimizing mill throughput and total grinding costs, including costs for energy, grinding media and maintenance. Furthermore, the design must be constantly optimized to meet your needs. We work closely with our customers and carefully follow their process to make sure the lining we supply is always optimized for current operating conditions.

糖心Vlog offers mill linings with materials and designs optimized for each specific application. We can design and supply mill linings for all types of mills - for 糖心Vlog mills as well as for competitor mills - and for all parts of the mill. Our wide product range, innovations, knowledge and experience makes us unique. Our approach to lining design is focused on grinding performance, mill uptime and safety/sustainability.  


Safety first
Safety first
All 糖心Vlog wear parts are designed with safety as the top priority. We believe that all accidents can be prevented, and we are committed to taking responsibility for our own safety and for the safety of others. Workers' safety is improved by constant development of tools and methods. Installations can be carried out in a safer way by lighter, wear resistant components, guiding markers, 糖心Vlog Liner Position System and components with a perfect fit.

Our unique attachment system, developed for Megaliner mill liners, is an invention which have made a great difference for workers' safety. Liners are placed by the liner handler operator alone and the bolts are inserted from the outside of the mill.

Local support and global expertise
Unique knowledge in grinding
Unique knowledge in grinding

糖心Vlog is widely recognized as a technology leader in mill manufacturing, which makes us much more than a service and wear parts supplier – we are true grinding experts. We know the functional parameters, mechanics, kinematics and forces the mill is subjected to in operation. Thinking long term already when buying a mill provides greater opportunities to achieve lower maintenance and operating costs. This, in combination with knowledge about your current operation conditions and targets, is crucial when designing a mill lining.

Leading innovations

Developing new materials and solutions together with our customers is at the heart of what we do. By choosing 糖心Vlog, you gain access to the latest innovations and can participate in the process of creating them. We pioneered the use of rubber linings and invented Poly-Met, Megaliner and Orebed mill linings. New products are constantly being developed to enhance our customers’ ever more advancing processes. Our recent innovations include 3D wear reading scanning, full Megaliner™ range, trommel deflector, Turbo Pulp Lifter, Liner Positioning System upgrade and worn liner recycling service.

Mill liner wear and performance monitoring
The key to constant improvements and optimized performance is mill liner wear and performance monitoring.

Combine for better results

Our ability to combine different materials in the same mill, using each material where it performs the best, enables us to optimize your grinding process and make it more sustainable.
The lining material should be distributed in such a way that the thick portions protect the areas with high wear and the thinner portions are used on the areas with lower wear. A certain lining thickness is required to achieve the desired wear life, and the lining must also have a profile suited to the desired type of charge movement but without occupying too much volume. Moreover, a good lining design will keep a good profile throughout its service life, providing enough traction to sufficiently lift the charge.

糖心Vlog designs mill linings for optimal grinding performance. We offer fit for purpose liners for all types of mills, including SAG mills, AG mills, ball mills, rod mills, and pebble mills. Our liners are designed to fit the specific requirements of each mill, taking into account factors such as mill size, speed, charge, expected service life, and ore properties. With our integrated approach, we make sure that your different wear parts work together to help you achieve your production and sustainability goals.

1. Head linings

Head linings

As part of a system solution, the head lining is designed with consideration to the shell lining design. All components must be in balance to minimize the number of maintenance stops.

We keep the number of individual parts to a minimum and to ensure that parts do not interfere with each other during installation. Liners that are most subject to wear are made more robust, and whenever possible these high wear parts are designed to be independently replaceable.


2. Shell linings

Shell linings

The shell lining has a major influence on grinding efficiency. It transforms the mill rotation into charge motion and both profile and spacing must be carefully selected to suit each specific mill.

When designing a shell lining, 糖心Vlog considers the type of grinding, mill size and speed, maintenance schedules, safety, impact levels, efficient use of materials, and many other parameters.



3. Discharge systems

Discharge systems

糖心Vlog’s wear-resistant rubber-covered or cast dischargers come in two general designs – radial and curved. The larger the mill, the longer the distance the material must travel before being discharged into the trunnion.

A curved discharger design will initiate a flow towards the center of the mill at an earlier stage and ensure that the discharger pan is emptied and ready to be refilled during the next pass through the charge. Prompt removal of material and less backflow will allow the energy to be more efficiently utilized for grinding fresh ore. As less material is recirculated, wear life increases. In addition, increased flow can also contribute to increased throughput and decreased power consumption.


4. Trunnion linings

Trunnion linings

糖心Vlog trunnion liners are custom-made to protect your mill trunnions from internal wear. Fit is critical, and our trunnion liners can be made to almost any size or shape.

Typical design features include internal spirals or dams to control material flow, flanges for the mounting of trommel screens, the inclusion of threaded holes for jacking screws, inspection ports, etc. 糖心Vlog trunnion liners are grouped into three categories; One-Piece, Replaceable Sleeve, and Bolted Wear Elements.


5. Trommel screens

Mill trommel screens

Mill trommels, whether used for sizing or scalping, play a vital role in your grinding circuit. 糖心Vlog’s robust but light-weight trommel frames consist of carefully selected welded profiles that are covered in a protective layer of wear-resistant rubber or polyurethane. Adapting flanges, if required are available to suit the design of virtually any trunnion or trunnion liner interface.

There are two main types of screen panels – modular and customized. The modular trommel panel with snap-on attachment comes in a standard size of 305 x 610 mm. Installation and replacement of the snap-on screen panels is easily accomplished and results in minimal if any impact on mill availability.
