Process Design

NCP utilize modified Bond Theory incl proven Service factors established from our extensive experience for Ball Mill Sizing.
SAG/AG mills are sized using a hybrid model including published information from Barrett, Austen & Morrell.
NCP has recently implemented a Specific Energy / Breakage Distribution model for SAG Mill sizing.
This model offers more circuit detail (e.g. PFD’s, PSDs, Mass Balance, Stream products) & covers the full comminution plant (crushing,/screening/milling/classification).

FEA completed with a 3-dimensional Structural Finite Element package integrated to our 3D Modeling Package.
Mill structures are sufficiently designed for max load in accordance with AAC323001
Design incorporates Casting Simulations Fatigue Analysis in accordance with BS7608 Fluid Film Analysis with outputs integrated into FEA stress predictions
