The influence of the following parameters has been studied: (i) speed of revolution of pelletizer disc, (ii) angle of pelletizer disc, (iii) moisture content, and (iv) duration of pelletization. Fractional factorial experiments using the ...
The maximum pelletization efficiency of fly ash aggregate was achieved with lower dosage level of high swelling bentonite. Higher factor levels facilitate enhanced ball growth, i.e., produce aggregate size fraction greater than 10 mm. Similarly, the maximum ten percent fines value and minimum water absorption result at the maximum …

Pelletization. Pelletization is a form of tumble-growth (agitation) agglomeration, whereby material fines are "grown" through a tumbling motion and the addition of water or a binding agent. This process is a …
5. Pellets can be prepared by a special technique called Pelletization. This technique is referred to an agglomeration process that convert fine powder or granules of …
A pelletization process is used to manufacture artificial lightweight coarse aggregate using fly ash. Pelletization depends on the size of particles and their distribution, the wettability of particles and moisture content, along with the process related parameters.
aggregates made from waste materials have a positive influence on the environment, the community, and the construction industry. The benefits of using waste materials can be summarized as follows: First, without using natural aggregates, natural resources are not depleted and damaging activities of aggregate mining are prevented.
The cold-bonding pelletization method polymerizes powdered material into aggregate particles with a specific particle size and then strengthens the particles to achieve the expected strength. This method can provide a new idea for the utilization of waste concrete fine powder.

Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from 1.2MTPA to …
The maximum pelletization efficiency of fly ash aggregate was achieved with lower dosage level of high swelling bentonite. Higher factor levels facilitate enhanced ball growth, i.e., produce aggregate size fraction greater than 10 mm.
Other studies have verified the pelletizing process through mixtures with other types of waste 53 or materials 54,55, or with different percentages of moisture.
The physical properties of fly ash, cement and lime used in the study were in the range of the physical properties of similar materials used in pelletization process as stated in literature [3]. It is mainly the grain size distribution and surface texture of material that influences the efficiency of pelletization process, possessing a wider ...
