Abstract

249,313. Ketin, T. March12, 1925. Addition to 247,683, [Class 59, Grinding, crushing, &c.]. Magnetic separators.-The apparatus for preparing and treating sand described in the parent Specification is provided with additional means for crushing the sand rejected by the sieves and removing metal bodies such as nails and broken bits of mould. The sand after passing between crushing rollers 88, 89 falls on a rotary magnetic separator 92 which is driven by chain gearing from the spindle 86 of the roller 88, the sand collecting at 111 on one side of a dividing plate 110 and the metal substances at 109. The magnetic separator consists of a drum divided into segments 92<a> - - d electrically insulated and magnetized in turn by currents which are automatically interrupted by a distributing device when the segments have passed the end of the dividing plate 110.
