Powder Compaction by Dry Pressing

In situ observation of the multistep process of cold sintering

“…This type of compaction gradient along the direction of the applied load will normally result in nonuniform densification of uniaxially pressed powders. 42 The height of the powder in the capillary is much too large with respect to the cross-sectional area for a typical dry powder compaction process. 43,44 This aspect ratio of powder was necessary given the small volume.…”

The influence of processing parameters on morphology and granulometry of a wet-milled sol-gel glass powder

“…The ceramic parts can be shaped either by dry or wet powder processing routes. The dry processing route includes pressing the powder to form a green body, and often requires the addition of processing additives such as binders to assist in the consolidation process, and to confer enough strength to the green bodies to enable safe handling and densification behaviour along the subsequent processing steps (2).…”

Performance Evaluation of Rotary Dryer and Granulator in NPK Steam Granulation Plant Production Department of IIB PT Petrokimia Gresik

“…The granulation running process highly affects the quality of the NPK fertilizer produced (Carvalho & Finzer, 2019;Erro et al, 2016;Herce et al, 2017;Izydorczyk et al, 2021;Putrawan et al, 2020). Agglomeration occurs in granulation process, namely the formation of a granule core from raw materials that have been fed from the hopper (Loh et al, 2011;Maharjan & Jeong, 2020;Nakamura et al, 2022;Oberacker, 2013;Singh, 2018). Steam or clay is added to it to facilitate the agglomeration process between particles (Chen et al, 2018;Pietsch, 2008;Wang et al, 2016;Yin et al, 2023;Zhang et al, 2021).…”
