A conical mill is a type of mill that is used to reduce the size of materials uniformly. It is also referred to as a conical screen machine. It is a hammer mill alternative. As the name implies, the mill varies in its diameters between its opening, in which the feed enters, and where the product leaves. ... The length covered by the mill is ...Web

There was a screen hole diameter hammer tip speed interaction (p < 0.001) for geometric mean particle size dgw (p < 0.001) and composite flow index (CFI) (p < 0.001). When tip speed increased from 3774 to 6176 m/min, the rate of decrease in dgw was greater as screen hole diameter increased from 2.3 to 6.3 mm.Web

Screen/Casing Diameter: Three-inch diameter casing and screen can easily be inserted into a 6-inch borehole, and allows creation of an effective 1.25-in-thick filter pack (especially important where the aquifer is composed of very fine materials).
