This paper reports the influence of post-melt impeller speed, post-melt processing time, binder concentration and particle size of bulk material on the sphericity of pellets produced by melt pelletization in a high shear mixer. Lactose was used as the bulk material with polyethylene glycol 3000 as a meltable binder. The sphericity of pellets was found to be affected by post-melt impeller speed ...

The low bulk density and low flowability of lignocellulosic biomass feedstock have been regarded widely as major barriers for a sustainable and efficient supply system. Densification of biomass is a viable option to increase the bulk (and inherent energy) density and flowability of feedstock, leading to improved efficiency of the supply system. The energy consumption of feedstock densification ...

The use of alternative raw materials is essential for establishing a circular economy in the mineral and ironmaking sectors. Therefore, this study investigates potential lime sludge as fluxing material during pelletization proposes an route usage waste. pellets were manufactured with different binary basicity values (CaO/SiO2) (0.15-0.45) bentonite (0.5-0.7 wt%) fixed carbon (0.5-1.1 contents. ...

The performance of a cold-bonding pelletization process was investigated for lightweight aggregates (LWAs) production from municipal solid waste incineration (MSWI) fly-ash (FA), by including multiple materials in the aggregate mixture. Before pelletization, FA pre-treated washing with water, which led to reduction chloride (66.79%) and sulphate (25.30%) content. This further confirmed XRF XRD ...

• High strength pellets were obtained using organic and inorganic binder combination. Maximum green was with 65 μm ironsand 0.1 wt% binder. Calcium-bearing binders increase sintered by forming liquid bonding phases. Direct reduction (DR) of iron ore hydrogen is a potential route for near-zero CO 2 steelmaking, but vertical shaft DR reactors require that fines must first be pelletized. This stud...
