Norcast uses charge motion simulation software to assist in the design of shell liners. For each individual simulation, different lifter configurations (height, style, face angle), mill speeds and charge properties are considered.

Simulations are run to predict the optimum mill liner profile based on operating conditions and to recommend progressive operating practices.

Fig 1 Trajectory Simulation Mill trajectory simulation prevents design decisions that might hurt mill performance while replacing the trial and error usually required to achieve ideal operating conditions.

Fig 2 Operational Recommendations Let Norcast marry your mill operating practices to the liner design.

All liners are designed with parametric 3D Solid Modeling software. Benefits include:

• Interference detection for accurate fit
• Direct input to CNC pattern manufacturing
• Reduced engineering cycles
• Ease of data sharing with 3rd parties such as mill and liner handler manufacturers and hardware suppliers

Fig 1 Wire Frame Ensures integrity of design, component fit and execution of design intent.

Designs are analyzed by our casting solidification simulation software prior to manufacture. This predicts the integrity of castings upon cooling, and has the benefit of:

• Casting integrity
• Process optimization
• Reduced product lead time
• Repeatable casting consistency

Fig 1 AS Cast Analysis The necessary gating into the mold is analyzed along with the casting to ensure the integrity of the entire pour.

Fig 2 Final Part Analysis The target geometry is then analyzed to ensure no unfavourable conditions exist which might impair the strength of the casting.

Compare and report on alternative designs with state of the art software. New designs can be compared to existing worn liners for direct feedback on liner lifecycle analysis.

Fig 1 Engineering Optimization New design data can be quickly compared to current conditions in order to predict the impacts of design changes under consideration.

Fig 2 Reverse Engineering Even worn systems can be examined to provide fast, accurate input to new designs.
