Abstract

1332020 Vibratory rod mills KLOCKNERHUMDOLDT-DEUTZ AG 1 Oct 1971 [10 Oct 1970] 45874/71 Heading B2A A vibratory mill comprises a casing earthed at one or both ends and charged with rods which are slightly shorter, e.g. 20 mm shorter, than the casing. This permits grinding of substances liable to electrostatic charging; e.g. thermoplastics material which has been first embuttled with liquid nitrogen.
