[ 1 ] - Application of perfect mixing model for simulation of vertical roller mills
Vertical roller mills (VRMs) are well-established grinding equipment for various tasks in the coal and cement industry. There are few studies on simulation of VRMs. In this research work, application of perfect mixing model for simulation of a VRM in a cement grinding plant was investigated. Two sampling surveys were carried out on the VRM circuit. The samples and data from the first survey wer...
[ 2 ] - Production of artificial stone slabs using waste granite and marble stone sludge samples
In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...
[ 3 ] - تولید سنگ مصنوعی از ضایعات سنگ تزئینی
سالانه میلیون‌ها تن ضایعات به اشکال مختلف در معادن و کارخانجات سنگبری ایران تولید می شود. در اغلب موارد این ضایعات در طبیعت رها می شوند که مخاطرات زیست محیطی را به دنبال دارند. در این تحقیق ضایعات درشت و پودر پساب کارخانجات سنگبری با رزین ترکیب و اسلب‌های سنگ مصنوعی تولید شده است. نتایج نشان می‌دهد اسلب‌های تولیدی دارای مشخصات فیزیکی و شیمیایی مطابق با استانداردهای ملی ایران برای سنگ ساختمانی م...
[ 4 ] - Influence of microwave treatment on surface roughness, hydrophobicity, and chemical composition of galena
The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...
