Karabulut, Gulsah; Ozkan, Gulay; Köroğlu, Deniz Günal; Öztekin, Sebahat
Agglomeration and size enlargement are essential in the food industry, significantly improving material handling, product performance, and process efficiency. This chapter explores the principles, techniques, and machinery involved in agglomeration, focusing on objectives such as enhancing flowability, reducing dust, and improving product quality. Key agglomeration techniques—including pelletizing, briquetting, granulation, prilling, spray drying, and extrusion—are explained, with a focus on their underlying mechanisms, the principles of particle size enlargement, and the factors influencing the process. This chapter also examines the role of binders, exploring how they, along with various additives, contribute to improved properties of the final product. The types of equipment, such as disc pelletizers, drum granulators, and high-shear mixers, are discussed in terms of benefits, limitations, and industry applications. Additionally, advancements in smart control systems, energy-efficient designs, and modular equipment are highlighted, illustrating the latest innovations in agglomeration technology.

This study aims to present an overview of the progress of geopolymer composites with regards to the latest developments on its constituents (binders, activators, and aggregates) and manufacturing techniques. Some ecological, economic, and industrial limitations of the traditional aluminosilicate binders yield to the pursuit of alternative ones over the period. Some of these latest binders e.g. ferrochrome ash, mine tailings, rice husk ash, red mud, have been highlighted in this paper. Current advances on replacement of natural fine and coarse aggregates such as mine tailings (iron ore tailings), recycled/lightweight aggregates for geopolymer preparation have been reviewed from the past literature. The paper also focuses on developments regarding the new class of green alkaline and acidic activators, which is traditionally considered to be the binding agent in the preparation of geopolymer composites. Different geopolymer production methods have been briefly discussed to study their effectiveness in achieving a strong and durable composite. This paper may serve to encourage further experimental research works for achieving more sustainable, cost-effective geopolymer composites with enhanced mechanical properties.
