Title
(EN) HEATING UNIT FOR ROCK MATERIAL
(FR) UNITE CHAUFFANTE POUR MATIERE ROCHEUSE
Abstract
(EN)
The invention relates to a heating unit for rock material, which is intended for heating and screening of rock material. The heating unit includes a rotating drum (10), conveyor devices (16) for feeding the rock material into the drum (10), a heat-developing unit (15), and a set of outlet screens (11) for screening the heated rock material. The drum (10) includes two coaxial jackets, an outer jacket (20) and an inner jacket (21). There is a fine screen (22) at the start of the inner jacket (21), through which the fines are arranged to travel to the space (23) between the inner and outer jackets and from there to the set of outlet screens (11).

L'invention concerne une unité chauffante pour matière rocheuse destinée à chauffer et cribler la matière rocheuse. L'unité chauffante comprend un tambour rotatif (10), des dispositifs de transport (16) destinés à acheminer la matière rocheuse dans le tambour (10), une unité de développement thermique (15) et un jeu de tamis de sortie (11) permettant de cribler la matière rocheuse chauffée. Le tambour (10) comprend deux gaines coaxiales, une gaine extérieure (20) et une gaine intérieure (21). On prévoit un tamis fin (22) au début de la gaine intérieure (21) à travers lequel les fines sont disposées pour se déplacer vers l'espace (23) entre les gaines intérieure et extérieure, puis vers le jeu de tamis de sortie (11).
