load, mill speed, grate/pebble port size and pebble crusher activity. There are two drawbacks to the approach of using A*b as the single parameter to describe the impact ... Guidelines for the use of JKSimMet for such simulations were given in Bailey . et al, 2009. Figure 4: A*b vs SAG kWh/t for operating AG/SAG mills (after Veillette and ...

o apertures in the grate are 100 % pebble ports with a nominal aperture of 56 mm Trommel. o Cut Size of 12 mm Pebble Crusher. o Closed Side Setting of 10 mm Feed Size Distribution. o F. 80. from the t. a. relationship given in. Equation 2 . The feed size distribution is taken from the JKTech library of typical feed size distributions and is

These include pebble crusher on vs. off comparisons, assessments of the effect of primary vs. secondary crushed feed, as well as surveys of mills operating fully autogenously and …

pumps, water supply, screens, crusher, cyclones, etc. The predicted plant performance (power draw, kWh/t and operating work index) is also presented a product of for each simulation. For Greenfield design of an AG/SAG-ball mill circuit with JKSimMet, the additional power requirement in the ball mill(s) is determined with the Bond ball mill work

By 2021 JKSimMet (JKMRC) and USIM PAC (CASPEO) had sold 600 and 300 licenses, respectively. ... the replacement of the HP Series pebble crusher with a TC84 crusher; and the addition of a pebble ...

parameter ta and crusher model energy matrices, the SMC Test ® can be used to conduct AG/SAG mill and crusher circuit simulations through the use of JKSimMet. Independent …

The fitted parameters included grinding rates in the SAG and ball mills and operating parameters from the cyclones, screens and …

The process model of CVO Concentrator Two from JKSimMet is presented in Fig. 12. Unlike the approach taken by Toor (2013), this model allowed for independent …

The SAG operates in closed circuit with pebble crusher at an average circulating load of 25%. The SAG production rate is 1,841 tons/hour and the discharge is carried out through grates (3" with approximately 9% aperture area) that feed two vibrating screens with 50% of 13-mm and 50% of 15-mm aperture.

RQD <70 >40 The ore or rock type is considered to be less competent and amenable to semi-autogenous grinding without a pebble crusher. RQD <40 The ore or rock type is considered to be incompetent and amenable to semi-autogenous grinding provided it is blended with more competent ores or is ground with a substantial ball …

Simulation of Comminution and Classification Circuits – integrating all tasks within one package. Latest Release - JKSimMet v6.3.1 - click for further information and to discover the new features JKSimMet is an award-winning, general-purpose computer software package for the analysis and simulation of comminution and classification circuits in …

Maximise ore characteristics and increase productivity with our powerful JK Drop Weight Test - an industry standard for use in characterising ore under AG/SAG milling conditions. The JK Drop Weight Test provides ore specific comminution parameters that are used in the JKSimMet software to analyse and/or predict crusher and AG/SAG mill performance.

Optimise your pebble crushing with HPGR. High Pressure Grinding Rolls offer an energy-efficient way to crush pebbles and alleviate bottlenecks caused by mills struggling to reduce the stubborn particles of hard ore. Whether recirculated through primary milling or separated and sent to a dedicated downstream pebble mill, pebble crushing is an ...

JKSimMet allows the user to: • Build a graphic-based flowsheet of the processing plant • Mass balance mineral processing circuits • Calibrate model parameters for the specific equipment in the circuit • Simulate the effect of changes in operating conditions and flowsheets to predict product flows, size distributions, and

JKSimMet integrates all tasks associated with data analysis, optimisation, design and simulation, including the storage and manipulation of models, data and results, within one package. Mass balancing and model fitting of complete circuits are standard features. It is fully interactive and operates with high resolution colour graphics.

JKSimMet simulations were used to test various operating and design conditions to improve the comminution process. Modifications to the SABC comminution ... The pebble crusher had an over-powered configuration. The installed power draw of 630 kW (actual power draw of 213.5 kW) is over-sized and therefore had a low operation efficiency. ...
