High Pressure Grinding Roller (HPGR) Remains One Of The Key Devices In Mines As It Offers Significant Energy Savings

 

High pressure grinding roller (HPR) is used for large-scale size reduction of rocks and ores. They use a combination of abrasive materials. The main advantage of HPR is that they have the ability to grind very hard and thick materials and generate very little heat. They also can be used to remove small particles from slag. They have the ability to grind on the flat top of the material or at the base, depending upon the type of material being processed.

High pressure grinding roller (HPGR) work can be used for cutting rough materials such as limestone, dolomite, granite, limestone, sandstone, quartzite, etc. They can also be used for coining and other abrasive finishes on slabs. They can be used on any kind of substrates including cement, rocks, gravel, etc. The applications of high pressure grinding rollers are numerous in nature. Some of the common applications include pre-cast concrete forms, countertops, flooring options, slabs, pipelines, pipe fittings, roof trusses, floor tiles, handrails, railway couplings, etc.

The technology behind the operation of HPGR and its applications depends on the specification of the application. If the anticipated applications demand high pressure grinding rollers with diamond grinding wheels, then the specification has to be specific. One of the most essential aspects of the application of the high pressure grinding roller (HPGR) is the specification of the expected operating conditions. During the initial stage of comminuting, the operating conditions need to be optimized to ensure the fastest and lowest possible speed. The expected conditions need to be recovered after each commuting cycle and the speed at which the abrasive material is released should be analyzed. This will ensure the optimized use of the machine in the future. Another aspect of the operating conditions is the type of material used and its suitability for the anticipated conditions. Recently, in August 2020, ThyssenKrupp introduced new HPGR Pro grinding roll.
