JK Drop Weight Tester

Developed at the JK Centre in 1992 and now a global industry standard, the JK Drop Weight Tester is a reliable tool for measuring impact breakage parameters for use in modelling and simulation using JKSimMet.

The JK Drop Weight Tester is the authorised specialist equipment required to conduct the JK Drop Weight Test, SMC Test® and the Integrated JK Drop Weight/SMC Test, all three tests are both proven global industry standards for ore breakage characterisation.

The JK Drop Weight Test provides ore specific breakage parameters which are used in the JKSimMet Mineral Processing Simulator software to design comminution circuits and analyse and/or predict AG/SAG mill performance. The same test procedure also provides ore type characterisation for the JKSimMet crusher model.

The device is enclosed in perspex and incorporates a variety of features to ensure operator safety. By varying the height from which the drop weight is released and the mass of the drop weight, a wide range of energy inputs can be generated.
