Electrostatic Powder Coating Spray Gun,Spray Machine,Paint System . A Brief About Powder Coating . One-year warranty . Powder coating is a dry finishing process, using finely ground particles of pigment and resin that are generally electrostatically . charged and sprayed onto electrically grounded parts.
Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues. The precipitator functions by applying energy only to the particulate matter being collected, without significantly impeding the flow of gases.

Oct 20, 2004· Abstract: This paper is aimed at investigating the possibility of sorting wheat seeds by electrostatic separation, The seeds are charged by ion bombardment using a corona discharge in the separator. The broken and complete seeds are charged selectively according to their surface area. The mass of the broken seeds is relatively smaller than that of the complete seeds.
An electrostatic separator is a device for separating particles by mass in a low energy charged beam.. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution.. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material.
