    The most critical tolerances are rotor-stator concentricity, controllable and repeatable gap setting, and stable rotor speed under load. Small deviations cause inconsistent particle size distribution and higher coarse residue, leading to sieve failures and poor storage stability. Seal integrity and shaft runout matter because leakage and air entrainment destabilize emulsions. Material tolerances and surface finish affect wear rate, which changes effective gap over time. For reliability, mills should allow precise gap calibration, vibration monitoring, and predictable wear parts replacement intervals.
