Abstract
A dispersing and grinding apparatus has a vessel for receiving a material to be processed and a grinding medium. A rotationally driven rotary shaft extends into the vessel and carries an agitator for dispersing, grinding and agitating the material within the vessel by the cooperative actions of the rotating agitator and the grinding medium. A separator removably installed at the discharge end of the vessel separates the processed material from the grinding medium so that the processed material is discharged from the vessel while the grinding medium is retained in the vessel for re-use. A mounting structures removably attached to the apparatus rotatably supports the rotary shaft and the separator. The mounting structure includes a sleeve removably slidably inserted onto a portion of the rotary shaft which extends out of the vessel. The sleeve is rotatably mounted on the mounting structure and releasably connected to the rotary shaft to rotate therewith. By detaching the mounting structure from the apparatus and disconnecting the sleeve from the rotary shaft, the mounting structure together with the sleeve and separator can be removed as a unit from the apparatus for service and repair without extracting the rotary shaft and agitator from the vessel.
