Up to that time, dry grinding in the sub-sieve range of 625 to 2500 theoretical mesh size range was impractical. In a jet mill, the temperature of the air leaving the jets is cooled to about -200 degs F due to the Joules Thompson effect and the product leaves no warmer than the air used for the grinding.

By the late 1990s the HPGR became standard equipment for processing iron ores. Successful hard rock mining installations followed about a decade later and HPGR applications have been expanding into base and precious metals flowsheets around the globe ever since, as the technology continues to prove itself on more complex and harder ores. There are several motivating factors that contribute to HPGR consideration for minerals processing.

Designed for your needs, the FLSmidth HPGR features Advanced Skew Control ASC via the hydraulic pumping system to the cylinders and monitored by linear variable differential transducers LVDTs. As skewing starts to occur in the floating roll, the ASC system adjusts the press force applied to the hydraulic cylinders, keeping the roll assemblies as near parallel as possible during operation, while at the same time allowing them to adjust to the segregation of feed conditions over the roll width, especially for larger machines.

Rolling Manufacturing Processes

Rolling Manufacturing Processes

In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes.
