“…There had a strong increase in the conductivity of materials when increasing their moisture content, and suggested that the water molecules adsorbed at the surface of the materials created a phase in which the charge carrying molecules (like ions) can move, creating electrical conduction across the powder surface. This decrease in resistivity (and thus the increase of powder's conductivity) with increasing moisture content has also been observed by Hemery [17], Engers [18] and Grosvenor [19]. As continuing to increase external moisture content, electrostatic forces decreased with increasing moisture content because of the conductive properties of water and liquid bridge of coal particles decreased the flowability as shown in Fig.…”

“…In general increasing the moisture content of a powder decreases its ability to flow smoothly. One of the main causes was the increased thickness of the adsorbed liquid layer, which increased the strength of liquid bridges formed between particles [14,[17][18][19]. However, only the surface moisture layer of particle, and not its pore or crystalline moisture, affected its flowability.…”

“…It has been proved by Liang et al [5], Hemery et al [44], and Nilsson et al [45] that there was a strong increase in the conductivity of materials when increasing their MC. The water molecules absorbed at the surface of the materials created a phase in which the charge-carrying molecules (like ions) can move, creating electrical conduction across the powder surface.…”

Based on the experiments of pulverized coal pneumatic conveying using nitrogen as carrier, the influences of riser inlet height above the gas distribution plate, riser diameter, pulverized coal external moisture content, and supplemental gas flow rate on the conveying characteristics such as pulverized coal mass flow rate and solid-gas ratio were investigated in a laboratory-scale experimental setup of a top-discharge blow tank under atmospheric pressure. There exists an optimal riser inlet height for a given top-discharge blow tank. The supplemental gas is one of the critical factors affecting the conveying stability and continuity. A model for material mass flow rate prediction with errors ranging from -25 % to +15 % is presented.

“…However, relative values of these dielectric properties also depend on tissue water content. These differences in tribo-charging potential were found useful to develop other separation methods than sieving ground tissues, especially when ultrafine particles were obtained (Hemery et al, 2009b(Hemery et al, , 2011b.…”

This paper reviews studies on green resource fractionation for two different types of material displaying a lignocellulosic or granular-type structure or a composite of the two. It explains how the identification of specific biochemical or spectral markers helps monitor tissue fate along processing and thus increase our knowledge on material fractionation. The key role of tissue mechanical properties in fracture behavior and the value of characterizing them were highlighted to better understand particle composition and properties. The effect of different modes of mechanical stress and strain during grinding as the main step of fractionation was illustrated. The value of different types of pre-treatment before or at grinding to reduce energy required to fracture and enhance dissociation or compound accessibility was presented. Separation methods based on differences in properties of the generated particles, and particularly innovative developments based on electrostatic sorting, were reviewed.
