  • application of analytical hierarchy process to selection of primary Crusher
    International journal of mining science and technology, 2014
    Co-Authors: Mohammad Javad Rahimdel, Mohammad Ataei
    Abstract:

    Abstract Selection of Crusher required a great deal of design based on the mining plan and operation input. Selection of the best primary Crusher from all of available primary Crushers is a Multi-Criterion Decision Making (MCDM) problem. In this paper, the Analytical Hierarchy Process (AHP) method was used to selection of the best primary Crusher for Golegohar Iron Mine in Iran. For this reason, Gyratory, double toggle jaw, single toggle jaw, high speed roll Crusher, low speed sizer, impactor, hammer mill and feeder breaker Crushers were considered as alternatives and capacity, feed size, product size, rock compressive strength, abrasion index and mobility of Crusher were considered as criteria. As a result of our study, the Gyratory Crusher was offered as the best primary Crusher for the studied mine.

  • simulation and optimization of Gyratory Crusher performance based on the discrete element method
    Powder Technology, 2020
    Co-Authors: Zere Che, Guoqiang Wang, Duomei Xue, Qiushi I
    Abstract:

    Abstract To study and optimize the Gyratory Crusher performance, taking the process of crushing iron ore by the Gyratory Crusher as the specific analysis object in this paper. First, the discrete element method (DEM) analysis model of the iron ore based on the bonded-particle model (BPM) is established. On this basis, the impacts of the mantle shaft angle, the concave angle, the eccentric angle, and the mantle shaft speed on the Gyratory Crusher performance are explored by the method of combination of DEM simulation and response surface methodology (RSM), and the performance prediction model of Gyratory Crusher is obtained. Finally, taking productivity as the main optimization goal and crushing force as the auxiliary optimization goal, multi-objective optimization is carried out through Design-Expert software, and the corresponding optimized values are 13°, 14°, 0.29°, and 129.63 rpm. The feasibility of the optimization results is verified, the productivity and the crushing force can be increased by 8.4% and 2.25 times, respectively. Meanwhile, the effective crushing distance of the ore particles in the crushing chamber is increased, which is beneficial for the ore particles to be better crushed.

  • The effect of different parameters on the power draw of miduk copper concentrator sag mill
    National Metallurgical Laboratory, 2010
    Co-Authors: Moaveni A Kamali, Noaparas M
    Abstract:

    The aim of this paper was to investigate on the effect of different parameters such as rotational speed, hold-up and load solid percent on the power draw of Miduk SAG mill. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one Gyratory Crusher which feeds one SAG mill (9.75 dia.(m) * 3.88 length(m)) following two parallel ball mills (5 dia.(m) × 7 lenght(m)). After SAG mill, a trommel screen produces two over and under size materials which the oversize part is circulated into SAG mill and undersize reports to hydrocyclone for further process. An experimental design was implemented in this work using d × 7 software for the above three mentioned parameters. As there is of course some effective factors which are significant on the mills performance such as feed hardness (grindability), liners conditions, but due to the existing variation in feed distribution and grind ability of feed, this decision was made to work on these two factors and accordingly the sampling and necessary analysis were performed. Due to similar technical reasons, it was not possible to change the ball load in SAG mill, as well. The results obtained from this work showed that optimized conditions for mill speed, hold-up and solid percent would be %68.05 of critical speed, 80 ton and %75, respectively
