As the nanoparticle market continues to swell, expertise is surfacing about nanoparticle grinding and dispersion processes. A grinding solution (wet grinding with agitator bead mills) achieves the production of nanoparticles with an average fineness of 40–100 nanometers (nm).…
Linde Gas (Murray Hill, N.J.; edlinks.chemengonline.com/6897-538) and partners have developed a high-pressure gas-delivery system that allows coating powders to be sprayed using liquid nitrogen at temperatures that do not melt the powder particles. The system has been optimized to support…
A feeder for both batch and continuous operation Available in 7 models with feedrates from 1 to 550 ft3/h, the Better-Weigh Feeders (photo) are designed to provide feeding in either batch or continuous mode, depending upon the arrangement…
The conventional way to make molded ceramic compontents involves the use of an organic binder (about 10-15 wt.%) to keep the shape of the fine ceramic powders. The binder is then burned off during the sintering process; this not only…
Modeling the behavior of bulk solids has been a longstanding challenge for researchers and practitioners alike. The differences between fluids, rigid solids and bulk solids can best be illustrated by their responses to applied stress. For instance, when…
With energy costs rising, the value of most powders and bulk solids has been rising steadily as well, giving manufacturers ample reason to improve production efficiency. "Companies not only want to reduce their consumption of power, they also…
There are a variety of reasons to consider the purchase of a new tank or silo1. As organizations grow, so does the need for increased storage capacity. Meanwhile, an old tank may become corroded or worn and require…
The need to transfer bulk-solids materials from the outlet of a bin or from a conveyor, to a process, truck, or another bin is ubiquitous throughout the chemical process industries (CPI). Transferring material using equipment designed to mechanically…
This improved planetary mill adds new safety features The premium line is a new generation of this firm's planetary mills for laboratory application (photo). Compared with traditional planetary mills, the premium line is said to provide 250% more…
Myths and misconceptions become part of accepted practice if repeated often enough. They are propagated by lack of fundamental particle-technology knowledge and by certain commercial interests. The list of presented here is by no means exhaustive. We have,…
