- Abstract
The largest fields of consumption of nepheline syenite are the glass and ceramic industries. Its not containing free silica, containing high alkali and alumina, high melting power, and narrow melting range are ideal characteristics for the glass industry. Its field of use in various branches of the industry and the largest reserves of this valuable raw material whose quantity is rapidly increasing are found in Russia, Canada, Norway, Brazil, China, and Turkey. Its mining in Turkey is done in the Akpınar region of Kırşehir. Akpınar-Kırşehir region nepheline syenite is one of the smallest intrusive masses in the Central Anatolian Crystalline Karm dish spread and consists of alkali plutonic rocks. As a result of nepheline syenite being seen as an expensive raw material other than its being accustomed to in terms of industrialists in Turkey, it is being consumed at low quantities. It has also been seen that scientific studies in an academic sense about this raw material, which has not been shown sufficient interest, are limited. The energy consumption occurring during the reduction of the particle size of the raw materials is related to the crystal structure, physical and mechanical properties of the rock. In this study, mineralogical, thermal, physical and mechanical properties and Hardgrove grindability of nepheline syenite in Akpınar-Kırşehir region were investigated. The mineralogical properties of nepheline syenite were determined by X-Ray diffraction (XRD) and thin section studies; The thermal properties were determined by thermogravimetric and differential scanning calorimetry (DSC/TGA) and firing color measurement. Physical properties of unit weight, water absorption rate and porosity values; Among the mechanical properties, Schmidt surface hardness, Ultrasonic P wave velocity and uniaxial compressive strength values were determined. In addition, the Bond work index value was calculated from the HGI value.
