Conical Mill Grinding Tests
The conical and cylindrical sections were built of cast iron, 1 ¼ in. thick and were lined with chrome steel lifting bars 2 ½ in. high, 3 in. wide and 16 in. long, set on 11-in. centers. The head bearing was adjustable in height, thus allowing the mill to be tilted any desired amount. Fig.1- Hardinge Mill Used in Grinding Tests.
