Robust HRC™ high pressure grinding rolls (HPGR) 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 ...
5. Increase in Tensile Strength. Cold working increases tensile strength at least 30% more than cut threads, which increases the strength of the thread. Additionally, rolled threads improve fatigue strength by 50% to 75%. Threads show no loss of fatigue strength, even when heated up to 500° F for several hours.
Roll ThreadingCapabilities and Approvals. Thread types: 60º thread form/machine screw type threads, Safety Critical Threads. Forms: UNR, UNF, UNC, UNJ, UNJF, UNJC (classes 1A, 2A, 3A, 5A) Metric forms: ISO and DIN (classes 6g and 4g6g) Sizes: .078 inch (2mm) to 2.500 inch (63mm) Material Hardness: Up to Rc45 depending on material type and size.
Grinding uses extremely fine micronized abrasives, and the machine tool, grinding tool, and workpiece are in an elastic floating working state. Under the action of low speed and low pressure, the convex points of the processed surface are successively ground, and the processing accuracy can reach 0. 1μm～0.01μm.
Rolls with a weight of up to 260 t, a length of 18 m and a diameter of 3 m can be processed to the highest quality standards. Thanks to a modular system and a wide range of optional equipment available, the grinding …
