Nip Pressure Measurement. The Nip Pressure Alignment Tool™ (NPAT™) is a complete nip pressure and force measurement tool that takes the guesswork out of machine set-up. By using real-time data, the NPAT verifies uniform pressure and nip contact. The tool measures and displays, in real-time, nip widths between 6.35 mm (.25") and 215.9 mm (8.5").

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.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.
