Met Dynamics Models · SysCAD
Dynamic Simulation
Time-dependent mineral processing simulation from equipment residence time and process control through to material movement, inventory and production.
Met Dynamics Models includes dynamic formulations for grinding and flotation, together with three-dimensional bulk solids storage. These operate within SysCAD’s wider materials handling, hydraulic and process control environment.
Investigate equipment response and control over minutes or shifts, or assess changing ore, material movement, inventory, availability and production over longer operating periods.
Applications
Two complementary scales of simulation
Weeks, months or years
Operational and production simulation
Track changing ore plans, material movements, inventories and equipment availability over an extended operating period. Maintenance schedules, interruptions and operating rules can be assessed against storage requirements and production targets.
Applications include production forecasting, surge and storage sizing, ore and blend planning, availability studies and evaluation of production constraints.
Minutes, hours or shifts
Process and control simulation
Represent equipment holdup, transport delays and control response during feed disturbances, setpoint changes, start-ups and stops. Evaluate how mills, flotation cells, bins, conveyors, pumps and valves interact.
Applications include control strategy development, assessment of operating transitions and investigation of transient process behaviour.
Process models
Dynamic detail where it affects the result
Detailed dynamic formulations represent process units where residence time and internal inventory materially affect performance, including AG/SAG, ball and stirred mills and flotation cells. The wider Met Dynamics Models library can be used alongside these formulations, allowing complete mineral processing flowsheets to participate in both short-horizon process studies and longer-horizon production simulations.

Bulk solids storage
Stockpiles and bins with particle size segregation
A stockpile changes the material delivered to the plant, not just the amount available for reclaim. Stacking, surface flow, segregation and withdrawal can alter the particle size and grade distribution in the discharge.
Met Dynamics’ three-dimensional storage model tracks full particle size distributions and species-by-size material properties through filling and reclaim. Conical stockpiles, chevron or windrow stockpiles and compartmented bins can be represented.
Connect storage behaviour to the process
Evaluate how stacking and reclaiming practices affect downstream feed variability, how different feeders draw material from the inventory, and how upstream or downstream interruptions alter storage behaviour.
The storage model operates within the wider SysCAD flowsheet, allowing its discharge to feed crushing, grinding and beneficiation models.
