Jesilix developed an automated control system for a column flotation process, focusing on precise liquid level regulation to ensure optimal separation efficiency and operational stability. The solution integrates sensor-based feedback, PWM-controlled actuation, and a PID control algorithm to maintain consistent column performance.
Problem Statement
Reduced separation efficiency from level deviations
Loss of valuable material
Increased operational instability
Manual/coarse control lacks precision under process disturbances
Objective
Maintain a stable liquid level within the flotation column
Dynamically adjust outflow based on real-time feedback
Ensure minimal oscillation and high responsiveness
Key Features Delivered
Non-contact Sensing
Improves reliability in chemically aggressive or particulate-rich environments.
PWM-based Flow Control
Precise modulation using standard solenoid valves, avoiding costly proportional valves.
Closed-loop PID Control
Ensures stability, responsiveness, and minimal overshoot.
