Abstract: The log washer with staggered paddles is a device for washing and separating aggregates, such as sand, gravel, ores, etc., from waste material. The log washer has a water tank or trough having one end inclined or raised relative to horizontal. A pair of shafts are mounted for rotation in bearings in the end walls of the tank, and connected to a driver by appropriate gearing so that the shafts rotate in opposite directions. Each shaft has a plurality of paddles mounted thereon, each paddle being mounted at an angle to the shaft to raise washed aggregates up the inclined trough to a discharge hopper or conveyor belt. Further, the paddles on each shaft are grouped in sections, the radial angle formed by adjacent sections with the shaft being staggered, the paddles on adjacent shafts being offset so that the aggregate material is ground between the paddles.
