Abstract
A supply pipe ( ) supplies a liquid to a comminution site ( ) at which the liquid is subjected to an electric field so as to produce charged comminuted material. An electrical discharge electrode ( ) produces ions to at least partially electrically discharge the comminuted material. A further electrode ( ) spaced from the comminution site ( ) by the electrical discharge electrode ( ) electrically attracts ions produced by the electrical discharge electrode ( ) away from the comminution site ( ) until sufficient space charge is built up to divert the ions towards the charged comminuted material to enable the ions at least partially to discharge the comminuted material.
