Production machine automation system EAPR

processfor process control

Overview
The EAPR automation control system is designed for automatic control of KAHL flat die pellet mills. It consists of a local control cabinet with a graphic touch panel (TP) and a PLC with Step 7 CPU as central components. The system monitors and regulates all critical process parameters. Optionally, the DISTAMAT module provides continuous roller-gap adjustment and regulation to maintain constant pellet quality. EAPR and DISTAMAT enable optimal press operation with reduced operator intervention.

Applications and advantages

• Single control platform adaptable to all press types and sizes
• Intuitive visualization using pictograms for rapid interpretation
• Fully automatic operation based on preselected process recipes and parameters
• Reduced unplanned downtime through system diagnostics and alarm management
• Storage and display of process data, error logs and alarm messages
• Integrated control and monitoring of pellet mill, proportioning screw, mixer, auxiliary units, cooler, and conveyors
• Load‑dependent pellet mill control and throughput regulation (t/h)
• Steam and liquid dosing control; up to four additional liquids can be dosed into the mixer
• Simple operator interface via the graphic touch panel
• Remote maintenance access for PLC and support from the KAHL Service Team
• Optional video monitoring for machine supervision
