triboelectrostatic fly ash beneficiation plant

Triboelectrostatic beneficiation of fly ash - ScienceDirect

01/05/2001  Triboelectrostatic beneficiation of fly ash is a dry method that does not have the disadvantages of wet cleaning, subsequent drying, and the processing of accompanying aqueous waste. In this process, fly ash is charged by triboelectrification. When two materials are in contact, electrons move until the energy level of electrons in each material at the interface is equalized. The material with ...
