Solids Processing

    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…

Ceramic molding without binders

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…

Don’t Fall For Common Misconceptions

    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,…

Weighing & feeding in the Spotlight

    Making sure the correct amount of material is fed to a batch reactor, bag or storage bin is important to everyone in the chemical process industries (CPI). Because the CPI cover such a broad spectrum, manufacturers are faced…
