Data driven particle size estimation of hematite grinding

2019125As a production quality index of hematite grinding process, particle size PS is hard to be measured in real time. To achieve the PS estimation, this paper proposes a novel data driven model of PS using stochastic configuration network SCN with robust technique, namely, robust SCN RSCN. Firstly, this paper proves the universal approximation property of RSCN with weighted least squares

Use of dry grinding process to increase the leaching of

202151Under wet grinding conditions, in addition to hematite and quartz, diffraction peaks of goethite appeared in the residue Celep and Serbest, 2015 Tsubouchi et al., 2005. This shows that under wet grinding conditions, part of the hematite is transformed into goethite, as shown in Eq. : 2 Fe 2 O 3 H 2 O 2FeOOH

Hybrid intelligent control for regrinding process in

201411Since hematite ore exhibits low grade, finegrained and nonhomogenous distribution, fluctuations occur frequently in its key variables during regrinding process. These key variables include the flowrate and the density of slurry produced in the first stage grinding, the underflow of the hydrocyclone and the dilution water flow added to the sump.

Estimation of Grinding Time for Desired Particle Size

202013Grinding Studies. Two kinds of mills, BBM and LBM, were used to achieve the desired P 80 passing percentage of 150 m with an acceptable range of hematite liberation > 75 at optimum grinding time. The BBM is a standard ball mill having a length and diameter of 300 mm 300 mm with smooth liner as shown in Fig. 2.A rotating drum is attached to a gearbox and has adjustable speed knob.
