Abstract
Abstract The liquid processing vessel in a sandmill is provided with lugs which fit over mating posts on a supporting column in a manner to permit the vessel to be readily removed from the support column for replacement, repair or storage. Tension on the belt driving the rotor in the vessel is easily relieved by an idler mechanism so that the rotor together with its drive shaft and pulley may be removed with the vessel as a unit. A heavy bracket at the midsection of the vessel is adapted to receive the tines of a forklift truck for handling the unit.
