HGM Ultrafine Grinding Mill Installation Guide
Step-by-step HGM ultrafine grinding mill installation guide. Foundation preparation, main unit assembly, classifier installation, electrical wiring, commissioning procedures for LIMING mills.
This case study presents a detailed account of a real-world grinding mill installation project by LIMING, including project background, equipment selection rationale, installation process, commissioning results, and ongoing operational performance. The information is based on actual project data and customer feedback, providing valuable reference for similar projects.
Site Preparation and Foundation
Before the HGM ultrafine grinding mill arrives, the installation site must be properly prepared. A reinforced concrete foundation of 200-300mm thickness is required, sized according to the mill model. The foundation must cure for at least 14 days before equipment placement. Ensure adequate space around the mill for maintenance access, material handling, and dust collection system installation.
Main Unit Assembly
The main grinding unit is the heaviest component. Use a crane rated for at least 1.5x the unit weight. Align the main shaft vertically using precision levels. The grinding ring must be seated flush against the base plate with no gaps. Install rollers and verify free rotation before connecting the drive system.
Classifier and Air System
The classifier sits atop the main unit. Install the classifier drive motor and connect the variable-frequency drive. The air blower must be positioned to minimize pipe bends. All air ducts should be sealed with high-temperature silicone gasket to prevent powder leakage and pressure loss.
Electrical and Control System
Wire the main motor, classifier motor, blower motor, and feeder motor to their respective variable-frequency drives. Install sensors for bearing temperature, vibration, and air pressure. Connect the PLC control panel and verify all interlocks function correctly before power-on.
Commissioning and Trial Run
After assembly, perform a dry run without material for 2-4 hours. Check for abnormal vibration, noise, and bearing temperature. Then conduct a load test with 30% capacity for 1 hour, gradually increasing to 50% and 80%. Monitor output fineness and adjust classifier speed as needed.
