THE MECHANICS OF TENSION CONTROL - Converter Accessory

The web must be "in traction" with all machine idler rolls and driven rolls to ensure proper web handling and control. • The web handling principal states a web will seek to align itself perpendicular to an idler or driven roll. This web handling principal is applied to route webs through processes with parallel idler rolls and driven rolls.

High pressure grinding rolls (HPGR) - Outotec

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
