Philosophy of Tega Mill lining solution

Tega C O I L Programme :

Working with an objective to deliver the following :

C- Capacity Enhancement

O- Optimised grinding

I – Installation time reduction

L- Liner Life Enhancement

Tega Mill liners are designed with the following objectives :

  • Increase mill capacity and throughput.
  • Maximise mill power draw.
  • Improved mill grinding efficiency
  • Uniform and longer mill liner life for reduction in mill down time so as to match plant’s maintenance schedule.
  • Design of mill liners with the aim of reducing mill liner installation time and mill liner removal without compromising on safety of equipment and people
  • Savings in Mill Liner Cost per Tonne of grind contributing positively to the grinding operation

Design Excellence

Engineering solutions are provided through our customized simulation packages used in Tega Mill liner Design.

 

Tega Soft (Discrete Element Method) :Simulate Mill Power draw, Power vs. Impact spectra & 3D-charge motion in a grinding mill. Used for optimizing mill lining design.
Application:
Ball Mill Liner
SAG Mill Liner
AG Mill Liner

Finite Element Analysis : for structural mechanical strength analysis of grate plates, lifter bars & fixing systems of Tega liner. This is used for Rubber Mill Liner, Rubber metal composite mill liners as well as TEGA Combi Liner.

FE Analysis of grate plates :

FE Analysis of lifter bars :

 

 

 

 

FE Analysis of fixing system :

 

 

 

 

Tega’s Mill Traj : Tega’s ball trajectory software to ensure proper grinding with suitable liner selection for a particular milling application. This helps in analyzing the behavior of mill liner inside the mill.
A fair comparison can be made between Steel Mill Lining and Rubber.

 

Tega Liner Wear Simulator

Tega WearSym is used to predict mill liner wear rate, remaining liner life & effect on mill performance. This helps mill operator to plan the changeover schedule & inventory management. Tega WearSym has been customized for Rubber Mill Liner, Rubber metal composite mill liners as well as TEGA Combi Liner.

 

3D Modelling

Modeling of each component to ensure perfect fit of Tega liners and discharger assembly system at the time of installation.

 

Tega FITSYM System :

All components for discharge system are tested for perfect fitment in a mill-end simulator (FITSYM) which ensures that the manufactured product fits easily in the actual application and reduces the time required for installation.

TegaTufSym:

Unique liner testing technology to simulate the real time tough grinding conditions and test components for reliability, mechanical stability and performance.

Services

Continuous evaluation of our Grinding Mill liners during operation is of utmost importance to us. Tega believes in periodic monitoring of liners as well as improvements in mill liner design so as to aid optimization of plant processes. Thus, Tega service personnel frequently visit our customers in order to collect wear measurement of our mill linings.

Data collection of the profile of the liner wear is done through specially designed wear measurement gauge. The data generated is then fed into our proprietary software so as to generate the current profile of the liner with estimated remaining life.

The visual analysis of the same is the true representation of the condition of the liners. We provide our customers with Wear Reports after every site visit.

However, what is not so apparent, but nonetheless given for each case is the advice based on more than thirty years of experience and predicted period of replacement. The liner data also assists us in optimizing the liner design so as to maximize life and improve mill capacity . This is a continuous process which has helped all our customers in maximizing value through their relationship with us.
