Abstract
A sandmill outlet screen is formed by a stack of rings which have projections and corresponding recesses stamped into them. The projections provide a gap between rings whereby flow passages between the rings are created. These passages permit the liquid being processed by the sandmill to flow out of the sandmill, but keep a grinding media in the mill. With the projections of one ring nested in the recesses of an adjacent ring, a small gap is provided. With the rings oriented to prevent nesting, a larger gap is provided. With the rings arranged so that the projections of adjacent rings abut each other, a still larger gap is obtained. This variable flow passage capability is further enhanced by varying the height of the projections.
