As natural resources become scarce, it is crucial to effectively recycle and reclaim WPCBs due to their high value and large output. Comminuting printed circuit boards is a crucial step in enabling the recovery of valuable materials, and this review provides an in-depth analysis of WPCB comminution. It explores the structure, types, and composition of the WPCBs, including their mechanical properties. The review thoroughly surveys conventional mechanical comminution machinery and also discusses emerging technologies such as innovative pretreatment approaches, electrodynamic disintegration, high voltage electrical pulses, and abrasive waterjet cutting. The literature has been critically examined to identify research gaps and inconsistencies, and future directions for increased efficiency and sustainability are proposed.}, year = {2024}, eissn = {1611-8227} } @book{MTMT:34559787, title = {A hulladék-előkészítés fizikai-mechanikai eljárástechnikai alapjai}, url = {https://m2.mtmt.hu/api/publication/34559787}, isbn = {9786155626852}, author = {Csőke, Barnabás and Faitli, József and Nagy, Sándor and Rácz, Ádám and Fehérné, Szirmai Zs.}, editor = {Csőke, Barnabás and Faitli, József}, publisher = {Miskolci Egyetemi Kiadó}, unique-id = {34559787}, year = {2024}, orcid-numbers = {Faitli, József/0000-0002-4037-5208; Faitli, József/0000-0002-4037-5208} } @CONFERENCE{MTMT:34490836, title = {Effect of the impact breakage type on the properties of White Fused Mullite particles}, url = {https://m2.mtmt.hu/api/publication/34490836}, author = {Tamás, László and Rácz, Ádám}, booktitle = {PARTICLE TECHNOLOGY FOR SUSTAINABLE PRODUCTS - BOOK OF ABSTRACTS}, unique-id = {34490836}, year = {2023}, pages = {711} } @{MTMT:34210818, title = {Városi bányászati kutatások a Nyersanyagelőkészítés és Környezettechnológia Intézetben.}, url = {https://m2.mtmt.hu/api/publication/34210818}, author = {Nagy, Sándor and Csőke, Barnabás and Bokányi, Ljudmilla and Mádainé Üveges, Valéria and Mucsi, Gábor and Faitli, József and Gombkötő, Imre and Rácz, Ádám and Bőhm, József and Romenda, Roland Róbert and Kurusta, Tamás and Dojcsák, M. and Horváth, F. and Csiszár, T.:}, booktitle = {100 éves a Nyersanyagelőkészítés és Környezettechnológia Intézet}, unique-id = {34210818}, year = {2023}, pages = {80-98}, orcid-numbers = {Mádainé Üveges, Valéria/0000-0003-4515-0697; Mucsi, Gábor/0000-0003-1031-2801; Faitli, József/0000-0002-4037-5208; Gombkötő, Imre/0000-0002-4683-2510} } @{MTMT:34199833, title = {Őrölhetőségi vizsgálatok fejlesztése}, url = {https://m2.mtmt.hu/api/publication/34199833}, author = {Csőke, Barnabás and Mucsi, Gábor and Faitli, József and Rácz, Ádám and Antal, G.}, booktitle = {100 éves a Nyersanyagelőkészítés és Környezettechnológia Intézet}, unique-id = {34199833}, year = {2023}, pages = {149-171}, orcid-numbers = {Mucsi, Gábor/0000-0003-1031-2801; Faitli, József/0000-0002-4037-5208} } @inbook{MTMT:34199704, title = {Finomőrlési eljárások fejlesztése keverőmalomban a Nyersanyagelőkészítés és Környezettechnológia Intézetben}, url = {https://m2.mtmt.hu/api/publication/34199704}, author = {Rácz, Ádám and Bohács, Katalin and Mucsi, Gábor and Csőke, Barnabás}, booktitle = {100 éves a Nyersanyagelőkészítés és Környezettechnológia Intézet}, unique-id = {34199704}, year = {2023}, pages = {172-191}, orcid-numbers = {Mucsi, Gábor/0000-0003-1031-2801} } @article{MTMT:34199558, title = {APPLICATION OF A GAS-SOLID FLUIDISED BED SEPARATOR FOR ALUMINIUM-COPPER SCRAP RECYCLING}, url = {https://m2.mtmt.hu/api/publication/34199558}, author = {Faitli, József and Rácz, Ádám and Vitányi, Márton and Nagy, Sándor}, doi = {10.31025/2611-4135/2023.18303}, journal-iso = {DETRITUS}, journal = {DETRITUS}, volume = {24}, unique-id = {34199558}, issn = {2611-4127}, abstract = {The EUbs circular economy concept necessitates the recycling of material streams used once or multiple times into the productionb consumption cycle again and again. The commonly known problem b that the number of recycling cycles of plastics is limited drives the economy towards metal usage again, because metal recycling cycles are limitless. Therefore, the efficient and economic separation of mixed aluminium and copper scraps in the 30b100 mm particle size range is an important issue for our society. In this study fundamental and applied research was carried out for the application of a gas-solid fluidised bed separator for aluminium-copper scrap recycling. A laboratory scale aero-suspension dense media separator was developed. Fundamental fluidisation experiments were carried out with this device and a powder rheometer. Afterwards pilot-scale and later industrial-scale separators were designed and built. The results indicate that the well-known Ergun fluidisation model can be the basis of a new process engineering design method for sizing dry fluidised bed separators.}, year = {2023}, eissn = {2611-4135}, pages = {13-22}, orcid-numbers = {Faitli, József/0000-0002-4037-5208} } @article{MTMT:34199497, title = {Effect of material bed compression on white fused corundum product particle shape and bulk density}, url = {https://m2.mtmt.hu/api/publication/34199497}, author = {Tamás, László and Rácz, Ádám}, doi = {10.1016/j.oceram.2023.100489}, journal-iso = {Open Ceramics}, journal = {Open Ceramics}, volume = {16}, unique-id = {34199497}, issn = {2666-5395}, year = {2023} } @CONFERENCE{MTMT:33732319, title = {Esősúlyos törési vizsgálatok alkalmazása kőbányászati anyagokon}, url = {https://m2.mtmt.hu/api/publication/33732319}, author = {Márkus, Izabella Rebeka and Rácz, Ádám}, booktitle = {XXIV.
