Particle Agglomeration

Agglomeration consists of a process capable of increasing particle size in a semipermanent aggregate form, known as granules, where the primary particles can be distinguished [1]. This process comprises a range of processing techniques employing solutions, slurries, melting, and binders [2]. In general, the liquid phase is sprayed onto a …

During agglomeration, rhodochrosite fines are first collided and adhered to each other due to hydrophobic attraction, forming small clusters with regular and relatively non-porous structures. When shear force is lower than binding force, the growth of agglomerates is dominant over its breakage. Thus, larger and more compact …

Controlling Particle Characteristics with Agglomeration

One technique that is especially useful in controlling particle characteristics is agglomeration (particle size enlargement), which converts powders and fines into granules. There are several different forms of agglomeration — some that utilize extreme pressure to form agglomerates, others that use heat, and so on.

Agglomeration of iron-BEARING fines: selection of the …

In the production of hot briquetted iron some fine by-product is generated. This material consists mainly of metallic iron and iron oxides. Before utilization of these fines in the steel mill and/or direct reduction plant, agglomeration is required. To get briquettes with sufficient strength a binder has to be added to the fines. In this study, the various …

Agglomeration Equipment Basics

The binder causes the fines to be tacky, allowing them to pick up more fines as they tumble on the disc. This results in an effect similar to rolling a snowball, referred to as coalescence. Agglomerators & Granulation Drums (Rotary Drums) Agglomerators, also known as agglomeration drums, fall under the tumble growth agglomeration category ...

The Sintering Process of Iron Ore Fines – IspatGuru

The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.

Comparison of industrial wastes as a binder in the agglomeration …

Coal agglomeration methods can be employed to decrease the volume of hazardous coal fines by making them useful. The quality of discarded coal fines is usually very low, but it can still be used industrially, e.g., to generate electricity [7]. Agglomeration methods include pelletising, briquetting, and spherical agglomeration [8].
