“…The method in question is called fluidized bed technology. 15,16 For this purpose, the Mini-Glatt A08459 equipment Glatt GmbH, Binzen, Germany was used. In order to use this technique effectively, it was necessary to establish the concentration of the inorganic components that are required for neutralizing the surface of the glass-ceramic granules in a preliminary test.…”

Two methods for coating glass–ceramic granules have been tested: self‐assembly in aqueous solutions and the fluidized‐bed technique. Both methods have been successfully used to produce nanocoatings on leucite–fluoroapatite glass–ceramic granules. Two chemical substances were developed for the experiments: (a) a combination of inorganic and organic compounds, (b) organic compounds alone, preferably comb polymers. Both groups of materials positively influenced the sintering properties of the glass–ceramics, because they suppressed tearing. The glass–ceramics were used to produce powder compacts for veneering materials, which would be used on metal frameworks (primarily multiunit dental bridges). With regard to the processing of the aqueous slurry, coatings with inorganic and organic substances are preferred.

“…The method was very useful, but limited to the Reynolds number and sphericity range due to restricted experimental materials. The second method is that the item Cd 0 in original Wen and Yu model (Cd = Cd 0 ε −2.65 ) was replaced by a single nonspherical particle drag model without changing the voidage function (ε −2.65 ), such as Ren et al (2014) and Cronin et al (2010). Obviously, this method ignored the effect of sphericity of particles on the voidage function.…”

“…Kevin confirmed that van der Waals and capillary forces can be ignored when the particle size is >100 μm. [ 32 ] Edge effects of the electric fieldThe electric field intensity at the boundary of the electrostatic field changes shortly. This is because, under the action of a strong electric field, the electric field intensity sharply increases at a position with a large curvature of the surface of the electrode plate.…”

Clean and efficient separation is an important requirement for the high‐value‐added recycling of end‐of‐life automobile polymers. In this study, polymer particles for vehicles were considered as research objects, and a two‐stage electrostatic separation device was designed to separate a mixture of three polymer particles. A kinematic model of friction‐charged particles in a two‐stage free‐fall separator was established. Then, a suitable time period for triboelectrostatic charging with regard to electrostatic separation was determined, and a charge–mass ratio distribution of mixed‐polymer particles, that is, polyamide (PA), polypropylene (PP), and polyethylene (PE), was measured using a Faraday cage based on the triboelectrostatic charging experiment of three types of particles in a friction barrel‐type tribocharger. The theoretical purities of PA, PP, and PE were calculated using the motion and particle charge–mass ratio distribution models were 100.00%, 89.51%, and 92.95% respectively. The experimental purities of PA, PP, and PE were 94.68%, 80.76%, and 84.27%, respectively, which is consistent with the theoretical purity. Results of the study can provide a theoretical and experimental reference for one‐pass electrostatic separation of three kinds of plastic particles.
