High Pressure Grinding Roll Test
Is the HPGR grinding alternative right for your application?
High Pressure Grinding Rolls (HPGR) are increasingly becoming a part of hard rock processing due to their energy efficiency, ability to induce micro-cracks and preferential liberation, coupled with high throughput and high reduction ratio.
JKTech offers two different High Pressure Grinding Rolls tests which are conducted at the JKTech pilot plant using a laboratory-scale Krupp Polysius machine:
Type A test: Ore energy response to HPGR – During this testwork, the best comminution to energy response is targeted and a minimum of six tests is normally carried out to achieve an effective characterization of an ore under different HPGR operating pressures.
Type B test: Ore variability response to HPGR – Ore variability tests are carried out on as many ore types as can be provided, to test the relative response of the ore to the same HPGR process settings.
We provide the test results in a detailed report where all data is interpreted and the behaviour of the test ores in the HPGR summarized.
Sample Requirements:
The recommended sample size for each HPGR ‘pass’ is between 20 and 30 kg. This is the minimum amount considered necessary to obtain an assessment under steady state processing conditions.
Download the Sample Transmission Forms, which include Sample Hazard Advice Form, and Quarantine Declaration Form. A completed Sample Hazard Advice Form must accompany every sample shipped to JKTech. In addition, a Quarantine Declaration Form must be completed for every sample originating from outside Australia.
Key Benefits:
- Reliably determine the HPGR suitability for your milling application
- Quantify any potential energy efficiencies of HPGR with your ore
- Determine any potential downstream effects of HPGR
