Screen House ACE is an advanced process control solution for mineral processing screen house operations, applying model predictive control to optimize screen feed distribution, deck utilization, and product size classification in crushing and screening circuits.
Screen House ACE applies ANDRITZ's Advanced Control Expert (ACE) platform to the optimization of screen house operations in mineral processing facilities. A screen house contains multiple vibrating screens that classify crushed ore by particle size, separating oversize material for recirculation to the crusher from correctly sized product for downstream processing.
Effective screen house control requires coordinating feed rate distribution across parallel screen decks, managing water addition for wet screening, maintaining optimal deck loading to prevent blinding or material bypass, and balancing throughput against product size specification compliance. Disturbances in feed rate, ore hardness, or moisture content can quickly cause off-specification product or reduced throughput.
Screen House ACE applies model predictive control to manage these variables as a coordinated system, maximizing throughput while maintaining product size specifications and protecting screen decks from overloading. The solution integrates with the plant DCS and existing instrumentation, supporting advisory or closed-loop operation.
