A Closer Look at Vertical and Horizontal Milling Machines

When you buy a horizontal milling machine, the spindle is pointing horizontally, and the table is horizontal but it is designed for threaded mounting holes or key slots, where a fixture or base is mounted, called a tombstone. The tombstone points vertically and presents the workpiece on another axis, explains Juras. In this instance, the workpiece is perpendicular to the spindle.

Optimizing your SAG mill operation International Mining

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at

Addition of pebbles to a ball mill to improve grinding

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19 75 181m). Batch tests in a pilot scale mill (0.57 m diameter) were used to compare ball milling to various ball/pebble mixtures. The mill power was measured online by monitoring lateral torque on a freely suspended motor
