A new process to produce titanium, called the TiRO process, has been developed by a team from CSIRO (Melbourne, Australia; edlinks.che.com/6901-538) through its Light Metals Flagship. The process is said to halve the cost of producing titanium metal components by: 1) Replacing the conventional Kroll-batch process with a more continuous process based on fluidized-bed (FB) technology; and 2) Using Ti’s...

    The screening process has always been the workhorse for solid-solid separation in chemical, pharmaceutical, food, mineral processing, coal and agricultural sectors. It can be done in dry or wet mode depending on the state of the feed and desired state of the product. It serves many purposes, for example scalping, separation of fines and coarse, dewatering, de-sliming and trash removal. Some...

    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). However, dispersion doesn’t always come as easily. Chemists and process engineers found that many...

    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 want to reduce product losses," says Scott Will, director of sales and marketing for Modern Process Equipment (Chicago, Ill.); "if you...

    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 grinding energy, says the manufacturer. The planetary mill is said to be as easy to operate as a centrifuge. The fool-proof grinding bowls are...
