Title (EN) HEAT TREATING OF MATERIAL IN FINELY DIVIDED FORM
(FR) TRAITEMENT PAR LA CHALEUR D'UN MATERIAU SOUS FORME FINEMENT DIVISEE
Abstract: front page image
(EN)A process and apparatus for heating and agglomerating particles of a resin polymer to improve the flowability thereof. Particulate resin polymer is introduced into one end of one of two peripherally intersecting cyclindrical drums (10 and 11), each having a longitudinal rotor (13 and 14) respectively. Spaced blades (16) radially mounted on each rotor (13 and 14) rotate to agitate and heat the resin particles, while causing the smaller and longer resin particles to coalesce and to form particles having improved flowability. The impact of agitated resins from each of the two drums (10 and 11) at the vicinity of the intersection adds further heating of the resin material.
(FR)Procede et dispositif permettant d'echauffer et d'agglomerer les particules d'une resine polymere afin d'ameliorer leurs caracteristiques d'ecoulement. La resine polymere particulaire est introduite dans une extremite de l'un de deux tambours (10 et 11) cylindriques se decoupant a la peripherie, possedant chacun un rotor longitudinal (13 et 14). Des lames espacees (16) montees radialement sur chaque rotor (13 et 14) tournent pour agiter et chauffer les particules de resine, tout en permettant aux particules plus petites et plus longues de se combiner et de former des particules possedant une caracteristique d'ecoulement amelioree. L'impact des resines agitees dans chacun des deux cylindres (10 et 11) a proximite de l'intersection provoque un echauffement ulterieur du materiau de resine.
