from an intermediate grinder might pass a 4O mesh screen; most of the product from a fine grinder would pass a 200 mesh screen with a 74 µm opening. An ultrafine grinder accepts feed particles no larger than 6 mm; the product size is typically 1 to 50 µm. Cutters give particles of definite size and shape, 2 to 10 mm in length.
