JK Drop Weight Tester

Developed by JKMRC, 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.

JK Gas Hold-Up Probe

JKTech provides a simple means to measure the amount of air contained in your flotation cell for optimum gas utilisation

Gas hold-up is the volume fraction of air contained within the pulp phase of the flotation cell. Generally increasing the gas content within the cell results in more bubbles per unit volume and hence more available surface area for particle-bubble interactions to occur, producing improved kinetics in the pulp phase. However, there is a maximum value of gas hold-up before the cell capacity is limited, resulting in reduced residence time.

JK Samplers

JKTech understands that effective sampling is the key to accurate characterisation and successful modelling and simulation

JKTech’s range of slurry samplers enables easy and representative sampling of industrial-scale flotation cells and slurry streams for the purposes of comprehensive plant surveys or simple circuit analysis.

The JK Dip Sampler can be extended up to a length of 3 metres to sample inside even the largest of industrial-scale flotation cells. Sample containers of 1L and 2L can be accommodated.
The JK Stream Cutter can be supplied in various sizes and handle lengths to facilitate easy and safe sampling of open slurry streams.
The JK Lip Sampler captures flotation cell overflow from the lip of flotation cells.
