Title:
ROLLER PRESS CAPABLE OF APPLYING ELECTRIC FIELD
Document Type and Number:
WIPO Patent Application WO/2019/034092
Kind Code:
A1
Abstract:
A roller press capable of applying an electric field comprises a base, a frame (12), press rollers, an inter-roller distance adjustment device (11), a speed adjustment device (122), a voltage application device, a feed deflector (19), and a discharge device. A surface of the press roller is made of an electrically-conductive material, and an electric field is created when a voltage is applied to the press roller. In the roller press, an alternating or direct current electric field is applied between the press rollers to create an electrochemical action, such that particles or a solution in a system is induced to undergo a physical or chemical change, thereby enhancing interaction therebetween, and accordingly increasing grinding and dispersion efficiency of a solid-liquid dispersion system.
