Have you ever tried to replicate a sieve analysis with your dynamic sieve analysis device? Look no further! Our new paper on the correlation of 2D and 3D particle characteristics has been recently published in Particuology. It has been available since November 5th: https://lnkd.in/euPQYn7R We took the discrete particle data from the Parrot database (https://lnkd.in/eJErVG6s) and simulated the results of both static and dynamic image analysis. The result are pleasingly accurate correlations for particle width and sphericity from 2D characteristics. With these correlations it may finally be possible to characterize 3D bulk data from dynamic image analysis measurements, taking the guesswork out of a long-established practice. The whole dataset is available online! Have a look and try to find some insights yourself – if you dare 🤠 #paperalert #particlecharacteristics #correlationshenanigans #mvtat

Nachhaltiger Schreddern – besser Verwerten: Erste Tests an neuer Anlage für #Batterie-Recycling 🔋 ♻ An einer neuen Schredder-Anlage untersucht ein Forschungsteam der #TUBAF Institute of Mechanical Process Engineering and Mineral Processing, wie Batteriezellen so zerkleinert werden können, dass möglichst viele der enthaltenen Rohstoffe effizient wiedergewonnen werden. In der neuen Anlage fangen die Forschenden auch leicht flüchtige Stoffe ein, die bisher verloren gingen. Sensoren und Kameras zeichnen die Prozesse auf und senden die Daten künftig an eine Datenbank zur Auswertung durch künstliche Intelligenz. Dadurch wird das Recycling effizienter und wirtschaftlich attraktiver. Die TU Bergakademie Freiberg ist damit die erste Forschungseinrichtung in Deutschland, die Recycling-Forschung an einer onlinefähigen Shredder-Anlage in Verbindung mit einer speziellen Forschungsdatenbank betreibt. 👍 In dieser Datenbank werden nicht nur die Ergebnisse aus der Anlage gesammelt, sondern auch viele weitere Daten von der TU Bergakademie und ihren Partnern am Standort Freiberg, wie dem Helmholtz Institute Freiberg for Resource Technology (HIF) at HZDR und dem #FraunhoferTHM, zusammengeführt. __ More sustainable shredding - better recycling: initial tests at new battery recycling plant sucessful A research team at TU Bergakademie Freiberg is using a new shredder system to investigate how battery cells can be shredded in such a way that as many of the raw materials they contain can be efficiently recovered. In the new plant, the researchers are also capturing highly volatile substances that were previously lost. Sensors and cameras record the processes and send the data to a database for analysis by artificial intelligence. This will make recycling more efficient and economically more attractive. This makes TU Bergakademie Freiberg the first research institution in Germany to conduct recycling research on an online-capable shredder system in conjunction with a special research database. This database not only collects the results from the plant, but also brings together a lot of other data from the TU Bergakademie and its partners at the Freiberg site, such as the Helmholtz Institute Freiberg and Fraunhofer THM. 📸 A.

With the end of Collaborative Research Centre SFB 920, a new open access book has just been published that summarizes the scientific developments achieved over the past 12 years by our (past and present) colleagues Jan Nicklas, Sarah Daus, Daniel Hoppach, Lisa Ditscherlein, and Urs Alexander Peuker. Our institute contributes three chapters: "Metal Melt Filtration in a Water-Based Model System Using a Semi-automated Pilot Plant: Experimental Methods, Influencing Factors, Models" (Chapter 12), "Microprocesses of Agglomeration, Hetero-coagulation and Particle Deposition of Poorly Wetted Surfaces in the Context of Metal Melt Filtration and Their Scale Up" (Chapter 15), and "Increasing Cleanliness of Al-melts by Additon of Ceramic Fibers" (Chapter 33).

Curious about #particle adhesion forces at elevated temperatures? In the latest paper, we look at what happens when it gets so hot that particles flatten or even melt on hot surfaces and how these adhesive forces differ from temperature-stable particles. The investigations were part of the DFG Collaborative Research Centre 920 and were carried out using two atomic force microscopes. Ready to get excited? Here is the full article: https://lnkd.in/dbwbPdar #sfb920   https://lnkd.in/dmMJuHrn #dfg https://lnkd.in/g_QmMRWm

Particle technology - paper allert! https://lnkd.in/enDxXTC3 In the realm of particle technology, the complexity of particles is key to their functionality. To address this, the priority programme SPP 2045 of the #DFG has been pioneering research on multidimensional particle systems. Instead of merely separating particles by size or composition, this innovative approach tackles separation by both size and composition, or size and shape simultaneously. To advance this field, a robust theoretical framework is essential for describing multi-dimensional particle property distributions and their Tromp-function. Our latest paper #KONA is a significant milestone, offering valuable insights and examples from various SPP 2045 projects. Dive in and explore the future of particle technology!

A #Lithium Ion #Battery consists of more than the electrodes... What about the cell casing? The latest paper by Malena Staudacher, Tony Lyon and Urs Alexander Peuker is dedicated to the processing and #recycling of the battery casing. It discusses common #sorting processes and the influence of selective deformation on the composite material. This research is embedded in the German federal activities in battery recycling greenBattNutzung - Recycling & Green Battery and Battery Utilisation Concepts and EIT RawMaterials RIS Hub Adria #AutoBatRec.

Particle technology, #batteryrecycling, and digitization have been presented at #WochederUmwelt. Now it's time to head back to Freiberg to fill the #DataMiningLab with content.

#batteryrecycling and #circulareconomy are the hot topics at this year's #WochederUmwelt, according to president Frank-Walter Steinmeier.
