JK Drop Weight Test
Maximise ore characteristics and increase productivity with our powerful JK Drop Weight Test – proven for nearly two decades.
Developed in the laboratory at the JK Centre in 1992, the JK Drop Weight Test measures impact breakage parameter to maximise ore characterisation and increase productivity.
The JK Drop Weight Test provides ore specific parameters which are used in the JKSimMet Mineral Processing Simulator software to analyse and/or predict AG/SAG mill performance. The same test procedure also provides ore type characterisation for the JKSimMet crusher model.
The JK Drop Weight Test is now an industry standard for use in characterising ore under AG/SAG milling conditions and is available at the JK Centre, various licensed commercial laboratories, and at in-house company laboratories around the world.
Sample Requirements:
1. The minimum quantity of sample required to provide sufficient particles for testing is 100 kg of crushed rock in the -75+12.5 mm size range, or 120 kg of drill core. JKTech can prepare a sample to the specified size range from a larger amount if required. For diamond drill core samples, the core must be un-split and have a diameter of at least 50 mm. Slightly more material is preferred if Bond rod mill and/or ball mill work index testing is also required.
2. Download the Sample Transmission Forms, which include Sample Hazard Advice Form and Quarantine Declaration Forms. A completed Sample Hazard Advice Form must accompany or arrive in advance of every sample shipped to JKTech. In addition, a Quarantine Declaration must be completed for every sample originating from outside Australia.
Key Benefits:
