Abstract
A grit washer is disclosed having a bearing assembly which supports a conveyor and which is removably mounted to the exterior of the grit washer tank. With the bearing assembly being mounted to the exterior of the tank, the bearing assembly is easily accessible without the need to drain the tank or lift the screw conveyor out of the tank. The bearing assembly can therefore be easily inspected, repaired and/or replaced as necessary. The external placement of the bearing assembly also isolates the bearing assembly from the abrasive grit in the tank thereby minimizing the damage to the bearing assembly caused by the grit.
