A seal assembly is provided for use to seal the drive shaft entry opening on the stationary end plate of a bead mill, wherein the stationary and rotary faces of a mechanical seal are preferably held in operative contact by a bellows which acts as a spring biasing means. Use of the bellows inside of the bead mill allows the rotary and stationary faces of the mechanical seal to remain in constant contact, and thus acts to prevent loss of grinding material and/or the slurry to be ground through either the mechanical seal surface, or the spring biasing means. An improved bead mill sealing structure is obtained.
