Abstract

The upper portion of the liquid processing vessel of a sandmill is provided with a large diameter tubular outlet. A cup-shaped filter to retain the grinding media in the vessel is placed in the outlet, and a cover having an outlet port is placed over the end of the tubular outlet. The filter can be easily removed for cleaning and selectively located in different rotational positions to even wear of the filter.
