“…Solovei et al [40] presented a method of granulating coal dust to obtain mechanically strong spherical granules with a diameter of 1 to 6 mm, with a dominant size of 3 mm. They showed that the composition of the granular material fraction can be significantly changed by introducing surfactants during the consolidation process.…”

This is a scoping review of agglomeration techniques to obtain of solid bodies from particle waste-materials for their utilization. For this purpose, the granulation and briquetting of fine coal and fly ash were presented in detail. Many successful works on solid fuels production, with coal only, and also with the addition of biomass, were presented. During the solid fuel combustion in power boilers, significant amounts of ash are generated. The properties of fly ashes were taken into consideration, and different methods of their utilization were proposed to obtain a wide range of useful products. Consequently, the waste resources of coal and ash were fully utilized. In final remarks, it was concluded, that the agglomeration techniques play an important role in waste management, but particularly in the circular economy.

“…However, the value of the internal stress in granules significantly depends on the type and size of the material. Solovei et al [2016] shows the method of fine coal granulation in order to obtain mechanically durable spherical granules with a diameter from 1 mm to 6 mm, 3 mm on Figure 2.

The development of mining and processing industries is accompanied by the formation of fine-grained waste materials that must undergo the treatment. Sometimes, grinding materials is a prerequisite for further processing. The issues of coal dust and fine coal granulation conducted to obtain homogeneous and persistent pieces for application in various branches of industry were presented. The article describes the binders and additives were applied in order to change the properties of the granules. The key factors affecting the process of fine-grained coal granulation is discussed. Granulated coal dust is most useful as an alternative fuel for combustion in industrial and household heating systems. However, carbon fuel requires a systematic control of the mechanical strength and resistance to external factors.

“…Asphalt-based spherical activated carbon is a spherical carbon material with asphalt as the main raw material, which is formed into spherical particles through unique processing technology, and then carbonized and activated at high temperatures in order to endow it with a high specific surface area, high adsorption performance, and high activity [ 1 ]. Asphalt-based spherical activated carbon is widely used in the military (armored motor vehicle and submarine life support systems, and response to biochemical war), environmental protection (purification of gas and liquid) [ 2 ], medicine (blood purification, drug treatment) [ 3 ], and chemistry (gas masks) [ 4 ]. It belongs to the top variety of the activated carbon family.…”

In the process of preparing asphalt-based spherical activated carbon, the molten asphalt must be formed into qualified spherical particles through the granulation process. Taking the process of molten asphalt granulation as the research direction, this paper carries out an asphalt rotational viscosity experiment and a thermogravimetric differential thermal experiment (TG–DSC), and obtains the optimal temperature and viscosity values for the asphalt granulation process. The fluent module in ANSYS software is used to input the known asphalt and prilling tower parameters. Based on the asphalt prilling principle, the thermal environment in the prilling tower during on-site melting and asphalt prilling is simulated. The results show that No. 70 matrix asphalt has good fluidity at 135 °C, and that, subsequently, the viscosity of the asphalt is stable and the fluidity of asphalt remains good with the increase in temperature; they also showed that the air velocity is fastest in the central area of the prilling tower, the air temperature is the highest at the top of the tower, and the air temperature in the central area is the lowest at the same height. Finally, a new approach to the granulation process of pitch-based spherical activated carbon is developed, which provides a reference for the basic experimental data and numerical simulation direction for the use of granulation towers to complete the granulation of molten asphalt in industry in the future.
