Title
(EN) ENERGY-EFFICIENT GRINDING ROLLS FOR COAL PULVERIZERS
(FR) CYLINDRES BROYEURS ECONOMES EN ENERGIE POUR PULVERISATEURS DE CHARBON
Abstract
(EN)
An energy-efficient grinding roll (18) for employment in a pulverizer (10) operative for effecting the pulverization of solid material therein. The energy-efficient grinding roll (18) includes a body portion (50) formed of a first type of material, an external surface (52) formed of a second type of material, and tread-like means (56) of preestablished dimensions and preestablished spacing provide on the external surface (52) such that the energy-efficient grinding roll (18) is capable of achieving as much as a 15 % reduction in the energy required to pulverize solid material when compared with the use of standard grinding rolls.
(FR)
Cylindre broyeur (18) économe en énergie destiné à être utilisé dans un pulvérisateur (10) dans lequel est effectué une pulvérisation de matière solide. Le cylindre broyeur (10) économe en énergie présente une partie de corps (50) constituée d'un premier type de matériau, une surface extérieure (52) constituée d'un second type de matériau, et des moyens en forme de marche (56) de dimensions préétablies et d'un écartement préétabli ménagés sur la surface extérieure (52) de sorte que le cylindre broyeur (18) économe en énergie est capable de permettre une réduction allant jusqu'à 15 % de l'énergie requise pour pulvériser une matière solide, comparé à l'utilisation de cylindres broyeurs classiques.
