Optimization of coagulation-flocculation process for treatment of a colloidal suspension containing dolomite/clay/borax
(Elsevier Science Bv, 2017)
This study statistically investigated the turbidity removal of a dolomite/clay/borax-containing colloidal suspension that had a high degree of stability. During the destabilization experiments, the mixing intensity, the ...
Optimization of a fully air-swept dry grinding cement raw meal ball mill closed circuit capacity with the aid of simulation
(Pergamon-Elsevier Science Ltd, 2015)
Production capacity of a fully air-swept industrial scale two-compartment KHD Humboldt Wedag (R) cement ball mill was optimized with the aid of simulation. It was proposed to operate the mill as a single compartment by ...
Effect of pre-crushing with a vertical shaft im-pactor (VSI) crusher on the performance of an industrial cement ball mill classification circuit
(Bauverlag BV GmbH, 2016)
A vertical shaft impactor (VSI) type crusher can also be used as a pre-crushing unit in cement grinding circuits to carry out an efficient grinding process. This type of application will reduce the total grinding energy ...
Effect of ball load and size distribution on grinding and classification performance
(Bauverlag Bv Gmbh, 2015)
An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag® ball mill on grinding and classification ...
Determination of deformation modulus in a weak rock mass by using menard pressuremeter
(Pergamon-Elsevier Science Ltd, 2018)
The deformation modulus of heavily jointed andesitic rock mass was investigated by using 41 Menard pressuremeter test results and geotechnical information obtained from seven geotechnical boreholes. The geotechnical borehole ...
Prediction of Top Coal Cavability Character of a Deep Coal Mine by Empirical and Numerical Methods
(Pleiades Publishing Inc, 2018)
Longwall top coal caving mining provides high productivity where thick coal seams exist. The study aims to predict the cavability character of the top coal for deep and thick coal seam in Soma lignite basin located at ...
Coagulation/flocculation process for marble processing plant effluent: Modelling and optimization through response surface methodology
(Wiley, 2019)
In this study, the coagulation-flocculation of a wastewater discharged from a marble processing plant was statistically analyzed and optimized. To make a systematic investigation on the coagulation-flocculation of the ...
