As a solution to this, Espey designed the Espey WD500 Special with 8 seal rings, and with connections for injecting water and air from stationary supply lines for a shaft diameter of 610 millimetres (24.02 “), a pressure of 6 bar (87.02 PSI), a temperature of 60 °C (140 °F) and a rotation speed of 60 rpm. The floating arrangement of the seal rings easily compensates for the radial movements of the shaft that arise from the heavy loading found in ball mills. Unlimited axial shaft movements can be absorbed by the Espey sealing system. The split construction of the housing allows the seal to be fitted without dismantling any of the ball mill's components or its drive, and is therefore extremely easy to service even when repairs are needed. Because the drive shaft of the ball mill does not have suitable wear protection, Espey designed a two-piece shaft sleeve with a suitable coating to protect the shaft. The sealing system has been used without failure or repair since 2007.
