Non-intrusive measurement of particle charge: Electrostatic dry coal cleaning

Technical Report · Wed Jan 01 00:00:00 EST 1992

DOI:https://doi.org/10.2172/5064968· OSTI ID:5064968

Research continues on a method using electric fields to separate coal and unwanted mineral matter. Simulations using spherical particles made of silica were performed to evaluate the charge measurement capabilities of the apparatus. Particle velocity and relative density data were collected for two different electric field strengths. The resulting velocity and density maps are displayed. A mathematical description of forces experienced by the particle within the apparatus is outlined. (VC)
