摘要： An attrition mill (10) for reclaiming foundry sand from deposited material having lumps of used foundry sand and included material includes a housing (12) defining a chamber (14) for receiving the lumps of used foundry sand and included material. A base (20) is disposed within the housing (12) and has an elevated end (22) defining a reject outlet adjacent a reject end of the mill (10) and a lower end (24), and a discharge wall (26) is positioned adjacent the base lower end (24) to define a sand outlet adjacent a sand end of the mill. A resilient support (32) is attached to the housing, and a vibratory drive (34) is attached to the housing (12) and includes first and second eccentrically loaded motors (36, 38). The vibratory drive (34) is selectively operable in a normal mode, in which the first and second motors (36, 38) are rotated to generate a vibratory force in a first direction that advances the deposited material generally toward the sand outlet, and a reject mode, in which at least one of the first and second motors (36, 38) is operated to generate a vibratory force in a second direction that advances the deposited material generally toward the reject outlet.
