This work aims to study the possibility of using an electrostatic drum-type separator prepare a powder with narrow size distribution curve for usage in additive manufacturing. The distributions uncoated commercial aluminum powders ASP-30, ASP-22, and ASP-5 were analyzed. It was shown that ASP-30 ASP-22 have similar asymmetric SPAN 1.480 1.756, respectively. powder, turn, has 0.869. chosen furth...

In this study, two different dust collectors, one based on an inertial separator and the other electrostatic precipitator (ESP), were developed in order to reduce brake wear particulate matter (PM) emissions. Additionally, collection efficiencies for particles (BWPs) of ESP evaluated according pad type. case separator, BWP low-metallic (LM) non-asbestos organic (NAO) pads similar, cut-off size ...

seed purification is one of the important agricultural processes to obtain high quality seeds. using modern technologies help producers to do this process with higher precision and accuracy. in order to separate seed impurities, a separation machine called tribo-aero-electrostatic separator was designed. the machine was evaluated by separating impurities of flixweed (descuriania sophia). primar...

Abstract In this study, several tests were performed to analyse the triboelectrostatic charging behaviour of an artificially mixed sulfidic copper ore consisting quartz and chalcopyrite. To check surface charge pure mineral samples, they analysed in a self-developed unit. After that, was sorted by using belt separator. The objective study is generate basic knowledge about furthermore sortabilit...

Abstract This paper described the plant scale catalytic process of plastic waste materials in order to obtain an alternative fuel from three wastes Polypropylene (PP), Polystyrene (PS) and Polyethylene (PE). Pyrolysis is thermochemical decomposition plastics at elevated temperatures (in absence or little supply oxygen) into a range useful products: gas, liquid, solid residue. These have consist...

At the Paul Scherrer Institute (PSI, Villigen, Switzerland) the new high-intensity muon beam line mE4 is currently being commissioned. It replaces the previous mE4 decay muon channel. The beam line with a design momentum of 28MeV=c has been planned to serve the needs of the low-energy, polarized positive muon source ðLE-mþÞ and LE-mSR spectrometer at PSI. A large acceptance is accomplished by i...

New fractionation technologies are presently under investigation in order to enhance the wheat bran nutrient value. The explicit aim of the present paper was to evaluate the possibility of using the electric field forces for the separation of the fine particles generated from each wheat bran tissue during the milling process. Corona charging and surface potential decay experiments were performe...
