Abstract
Abstract Apparatus for feeding mineral ore or other objects to a point of use comprises a drum having a plurality of parallel, circumferentially extending grooves, and a driven endless belt which contacts or is disposed closely adjacent to the drum and which has a vertically extending and a horizontally extending run upstream and downstream respectively of the drum, objects which have been fed to the said vertically extending run entering the said grooves and being carried onto the said horizontally extending run to form parallel lines of objects thereon which travel towards the point of use.
