old ore wet ball mill wheel foot pedal

The ore from the mine was trammed 4,000 feet from the working face to the mill. There it was dumped into a 150 ton coarse-ore bin that fed to a 12 x 18 inch jaw crusher. A 18-inch belt conveyor carried the rubble to the fine ore bin which fed to another conveyor that carried the ore to a 4.5 x 6 foot Marcy-type ball mill that turned at 28 rpms.
