Yttria-reinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM), respectively, followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y2O3 composites. It is found that Cu–Y2O3 composites synthesized by DBM exhibit better densification, …
For each grinding test, the mill was first loaded with a 1.86 kg mass of ball mix and a 150 g mass of feed sample material.A volume of 64.0 ml tap water was then added to the mill charge in order to make a 70 wt.% pulp density.Four mono-sized fractions of quartz and chlorite(− 2 + 1.19 mm, − 1.19 + 0.5 mm, − 0.5 + 0.25 mm, − 0.25 + 0.15 …
Recent papers on the role of grinding aids in wet ball mills indicate that certain polymeric aids favorably act by altering pulp rheology, leading to improved production rates at high pulp densities. Analysis of recent data indicates that there can be an improvement in terms of the production of fine particles per unit time, but on the other ...
In terms of final particle size, wet ball milling is more suitable to reduce the particle size below 1 µm compared to dry ball milling . In addition, wet ball milling suppresses the role of surface forces and prevents the agglomeration tendency of fine particles to get narrow particle size distribution . Dry ball milling produces particles ...
The mass ratio of milling media to biochar during wet ball milling was demonstrated as the most crucial parameter and the best performance was obtained at 100:1 (Peterson et al., 2012). Despite being comparatively less effective, salt-assisted dry ball milling could also increase the total surface area and the proportion of micropores …
