This study investigates the influence of wood pellet properties on the grindability of pellets in a lab-scale disc mill. The pellet properties investigated included wood type, moisture content, internal pellet particle size distribution, particle density, and durability. Two pellet qualities for industrial use (designated I1 and I2 as per ISO 17225 …

The objective of this work is to give an overview of the influence of torrefaction temperature and residence time on important fuel parameters like chemical composition, heating value and grindability. Additionally, the energy demand of the torrefaction reactor is measured to determine the heat of reaction, which is an important …

The grindability of a coal is a measure of its resistance to crushing. Two factors affecting grindability are the moisture and ash contents of a coal. In general, lignites and …

This research investigates various methods able to identify possible mineralogical, physical and chemical influences on the grindability of commercial clinkers with high MgO level.

Although it is known that electroplated bond is hard (prevents pull out of abrasive) compared to resin bonded wheel, during grinding, the resin bonded diamond wheel will enable self-sharpening of the diamond abrasive, enabling better grindability.

The aim of this study is to investigate the different factors that influence the chemical and mineralogical composition of cement clinker and their effects on required energy potential during cement grindability and comminution.

This fundamental study sheds light on the grindability of microstructure variations of through hardened A485–1 grade steel. Results indicate that the phase composition and carbide distribution significantly influence grindability which is characterized in terms of specific grinding energy, G-ratio and part distortion.

Accordingly, it is expedient to assess the influence of the composition, structure, and properties of coal on its Hardgrove grindability, with the determination of valid correlations.

This paper focuses on a related aspect: the influence of charge distribution on the specific comminution energy in crushing and milling. Small-scale blasts have been performed on 14 limestone blocks with different P.Fs. and charge distribution.

Nickel-based superalloy is a typical hard-to-machining material in the aero-engine manufacturing industry. The grindability difference of two kinds of nickel-based superalloys, i.e., equiaxed cast nickel-based superalloy K4125 and wrought nickel-based superalloy Inconel718, are discussed in this article. The influence of grinding …

The influence of the aforementioned parameters on HGI was assessed. It was found that, among the investigated coals, the mean random vitrinite reflectance value, a measure of the coal rank, was the parameter that had the most significant effect on coal grindability (positive correlation).
