Title (EN) METHOD AND APPARATUS FOR HEATING ROCK MATERIAL
(FR) PROCEDE ET APPAREIL DE CHAUFFAGE DE MATIERE ROCHEUSE
Abstract:
(EN) The present invention relates to a method for heating rock material when concrete, asphalt mix and similar products are produced. According to the method, rock material is heated by the combined action of a heating unit (7) located above the conveyor and a heated heat-transmitting conveyor (6). Heat is transferred by the convection from the heated heat-transmitting conveyor (6) to the material that is being transported. Further, the invention relates to an apparatus for heating rock material. The apparatus comprises a heat-transmitting conveyor (6) which is heated, either merely by a heating unit (7) located above it, when the conveyor is not used for charging, or by a separate, additional heating device (9) or by a combination of the above mentioned alternatives.
(FR) Procédé permettant de chauffer de la matière rocheuse lorsqu'on produit du béton, un mélange d'asphalte ou des produits similaires. Selon le procédé, on chauffe la matière rocheuse sous l'action combinée d'une unité de chauffage (7) située au-dessus du convoyeur et d'un convoyeur (6) transmetteur de chaleur chauffé. La chaleur est transférée par convection à partir du convoyeur (6) transmetteur de chaleur chauffé au matériau transporté. Est également décrit un appareil de chauffage de matière rocheuse. L'appareil comporte un convoyeur (6) transmetteur de chaleur qui est chauffé, soit simplement par une unité de chauffage (7) située au-dessus, lorsque le convoyeur n'est pas utilisé pour charger, soit par un dispositif de chauffage séparé supplémentaire (9), soit par la combinaison de ces deux dispositifs.
