Classification of Fine Particles

Particulate Science and Technology, 1997
ABSTRACT Experimental results with two new classifiers for in-line and off-line operation are presented. The first type is a cyclone classifier, in which the vortex finder is exchanged with an impeller wheel enabling cut sizes between 5 and 100 µm.

Quantification and Characterization of Fine Plastic Particles as Considerable Components in Atmospheric Fine Particles

Environmental Science & Technology
The negative effects of air pollution, especially fine particulate matter (PM2.5, particles with an aerodynamic diameter of ≤2.5 μm), on human health, climate, and ecosystems are causing significant concern. Nevertheless, little is known about the contributions of emerging pollutants such as plastic particles to PM2.5 due to the lack of continuous ...

Strongly coupled fine particle clouds in fine particle (dusty) plasmas

Contributions to Plasma Physics, 2017
Based on drift‐diffusion equations, we show a large enhancement of the charge neutrality in fine particle clouds analytically and confirm it by numerical solutions, in both cases of microgravity and gravity. This observation enables us to construct simple models of fine particle clouds in both cases.

Fluidization of fine particles

Chemical Engineering Science, 1998
Experiments on the fluidization of fine particles (Geldart group C) with mean sizes 0.01-18.1 mu m and densities 100-8600 kg/m(3) were conducted. Experimental results show that the process of fluidizing fine particles usually involves plugging, channeling, disrupting, and agglomerating.

Fine-particle magnets

Electrical Engineering, 1957
The unusual properties of fine-particle magnetic materials offer challenging opportunities for research aimed at the development of powerful new permanent magnets. In this article, the permanent-magnet properties of fine particles are summarized and compared with those predicted on a theoretical basis.

Flocculation of Fine Particles

1992
The basic principles of colloid stability, destabilisation and flocculation are reviewed, starting from the effects of simple salts. The role of adsorbed materials, especially polymers, on stability is considered in some detail and some practical implications are discussed. Factors influencing the rate of flocculation are outlined and the importance of
