Abstract
An attrition mill for reclaiming foundry sand from deposited material having lumps of used foundry sand and included material includes a housing defining a chamber for receiving the lumps of used foundry sand and included material. A base is disposed within the housing and has an elevated end defining a reject outlet adjacent a reject end of the mill and a lower end, and a discharge wall is positioned adjacent the base lower end to define a sand outlet adjacent a sand end of the mill. A resilient support is attached to the housing, and a vibratory drive is attached to the housing and includes first and second eccentrically loaded motors. The vibratory drive is selectively operable in a normal mode, in which the first and second motors 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 is operated to generate a vibratory force in a second direction that advances the deposited material generally toward the reject outlet.
