1. Structural Leg Positioning & Anti-Overturning Bracing
Elevate mixer legs (clearance 3.8m or 4.5m for batch transfer hopper) with verticality deviation $\le$ 1/1000.
Perimeter weld leg footplates to embedded steel plates with full-penetration welds ($h_f \ge 10$ mm) and cross diagonal sway bracings.
2. Pneumatic Discharge Gate Calibration
Install one-way flow throttle valves on pneumatic cylinders to calibrate opening duration (1.5–2.0s) and closing duration (2.0–2.5s), eliminating impact slamming.
Adjust door seal compression to 3–5 mm; perform hydrostatic leak check to verify zero slurry dripping.
3. Centralized Auto-Grease Pump Priming
Purge all air from lines leading to the four shaft-end mechanical seals using manual bleeder screws.
Fill reservoir with NLGI 0/00 extreme-pressure lithium grease; perform continuous manual jog cycle until fresh grease beads evenly around all 4 outer seals.
