Greater productivity, more resistance and less wear

Tega innovated with the Dynaprime composite liner, joining plates and lifters in one piece at SAG mills, resulting in reduced assembly times and increased equipment availability.

Application:

The solution incorporates composite materials and integrates various manufacturing technologies to create a product that is lighter, more durable, and has an extended shelf life.

  • Tailored solutions designed to meet each client's specific needs.
  • Utilizes advanced polymers and steels with high fracture toughness.
  • Strong adhesion exceeding 200 Kg/cm2.
  • Large dimensions and low weights streamline assembly by reducing the number of parts and external bolting, thus minimizing assembly times and associated risks.
  • Tega's bolted-from-the-outside fastening systems effectively isolate dynamic loads on bolts, reducing the likelihood of release and fatigue shear.
Problems at a glance:
  • Enhanced product durability and shelf life.
  • Streamlined assembly process leading to reduced operational costs.
  • Significant energy savings in larger mills, contributing to sustainability goals and financial savings for customers.
Results:
  • Tega's unique design establishes a new standard for SAG coatings globally, boasting an extended lifespan and facilitating quicker assembly. This results in lower operational costs for customers.
  • Studies reveal significant energy savings attributed to Tega's solution. In Ball Mills larger than 25 feet, energy savings of up to 7000 MWh/year are attainable due to its reduced weight. Similarly, in 34-foot SAG Mills, savings exceeding 2MUSD per year are demonstrated, primarily due to increased availability.

"Dynaprime in SAG mills allows: install coatings up to 40% more lightweight, reduce assembly time by 30% and rule out the occurrence of fractures or detachments, which increases the availability of the equipment. Customers get used to the fact that the product does not fail", he says
