The impact of limestone fragmentation on raw mix production in cement industry
Raw mix design is one of crucial point in production of clinker. Cement industry use limestone, marl, clay in particular percent to provide the best quality in production of clinker. The quality of the material must be in line with the quality targets. Fragmentation is important element, because affect preblending design, economic norm from blasting to crusher. Blasting is an operation which affects all subsequent operations and costs. The Kuz-Ram model is possibly the most widely used approach to ...Nikola Đokić, Lazar Kričak, Stefan Milanović, Marinko Pavlović, Stefan Krstić.

Smatra se ,,modifikatorom'' zemljišta i koristi se kao đubrivo i kao rezervoar za skladištenje ugljenika. Kvantifikacija funkcionalih grupa je važna zbog hemijske reaktivnosti biougljeva koji imaju uticaj na svojstva zemljišta. U istraživanju su korišćena 3 uzorka biouglja različitog porekla i jedan referentni, aktivni ugalj.

Stratigraphic implications of the Mio-Pliocene geodynamics in the area of Mt. Avala: new evidence from Torlak Hill and Beli Potok (Belgrade, Serbia)
Mt. Avala is located on the southern margin of the Pannonian basin (SPB), a border zone between the uplifted morphostructures of the Dinarides and Carpathian-Balkanides. Similar to the Pannonian basin, tectonostratigraphic evolution of the Mt. Avala area during the last 23 Ma has is characterized by syn- and post-rifting processes as well as tectonic inversion. Here, we present the results of field investigations of the Miocene‒Pliocene dynamics that led to different spatial positions of the same stratigraphic units (e.g. ......

Dalibor Erak (2019)Predmet istraživanja doktorske disertacije je tektonska evolucija područja planine Jastrebac u centralnoj Srbiji, gde višefazna tektonska aktivnost od mezozoika do danas komplikuje rekonstrukciju strukturnih odnosa i geološke evolucije ovog prostora. Kompleksna višefazna evolucija planine Jastrebac u Srbiji je demonstrirana kombinovanjem kinematskih podataka prikupljenih na terenu i mikrostrukturnih opservacija sa dodatnim termohronološkim podacima “fission track” i podacima odredbe starosti metodom U-Pb na cirkonima.
