In lead-zinc sintering process, various kinds of lead-zinc concentrates and returning powder from ineligible sintering production are blended and then sintered in updraft sintering machine to produce agglomerate for imperial smelting process. It is required to determine a proper mixture ratio for these materials blended to assure sintering production indices such as agglomerate composition and ...

The preparation of nanofluids is very important to their thermophysical properties. Nanofluids with the same nanoparticles and base fluids can behave differently due to different nanofluid preparation methods. The agglomerate sizes in nanofluids can significantly impact the thermal conductivity and viscosity of nanofluids and lead to a different heat transfer performance. Ultrasonication is a c...

Delivered dose was calculated by using the In vitro Sedimentation, Diffusion and Dosimetry (ISDD) model developed by Hinderliter et al. [1]. The ISDD model is based on the general dynamics of particles in viscous media where mass transfer is driven by diffusion and sedimentation [2–4]. Because environmental conditions in in vitro—experiments are homogenous, advection is assumed to be negligible...

Considering the prediction of sulfur in agglomerate in sintering process, a prediction model based on intelligent integrated strategy is put forward in this paper, where the mathematical model calculates the sulfur content in agglomerate following material balance equation with some parameters predicted by NN method, while the expert rule model describes the relationship between sulfur quantity...

The dependence of technical lead production on the composition of the agglomerate has been analyzed on “WaterJacket” furnace in Trepça. Additionally, the theoretical and real raport of coke consumption per ton of technical lead was studied. The goal of this study was to optimize the parameters of the process with respect to the amount of technical lead produced, the amounts of lead in the agglo...

Partially stabilized zirconia (PSZ) agglomerate toughened alumina has been prepared by the "deflocculation-flocculation" technique, using 2 and 3 mol. % Y2O3-doped zirconia powders. Samples containing up to about 30 vol.% zirconia were obtained. The resulting microstructure seems to be mainly influenced by the physical properties of the starting powders, e.g. agglomerate size and the specific s...

CPL-active agglomerate materials with unique polarization have promising applications in 3D optical displays, encryptions, biological probes, chiral photoelectric devices, and CPL switches. This review systematically summarizes advances of aggregate solid materials, will give inspiration for the design application CPL-exhibiting materials. (Aggregate. 2021;2:e48)

A model for the simulation of the steady-state impedance response of a polymer electrolyte membrane fuel cell ~PEMFC! cathode is presented. The catalyst layer of the electrode is assumed to consist of many flooded spherical agglomerate particles surrounded by a small volume fraction of gas pores. Stefan-Maxwell equations are used to describe the multicomponent gas-phase transport occurring in b...
