Title (EN) METHOD AND APPARATUS FOR TREATING PULP
(FR) PROCEDE ET APPAREIL DE TRAITEMENT DE PULPE
Abstract: front page image
(EN)A method and apparatus for treating pulp prior to being made into paper, which treatment is known as beating or refining. The method comprises feeding a slurry of the pulp to the narrow nips of grooved rolls (14, 15) at which the slurry of pulp is partially dewatered. Then, almost simultaneously, fragments of the pulp are subjected to a predetermined heavy pressure, then dispersed before being subjected to the same sequence until treated to the desired degree.
(FR)Procédé et appareil de traitement de pulpe avant sa transformation en papier, ce traitement étant connu sous la dénomination de raffinage en pile ou de raffinage en raffineur. Le procédé consiste à amener une boue de pulpe jusqu'à l'intervalle étroit entre des rouleaux rainurés (14, 15) où la boue de pulpe est partiellement déshydratée. Ensuite, mais pratiquement simultanément, des fragments de pulpes sont soumis à une forte pression prédéterminée, et dispersés avant d'être soumis à la même séquence jusqu'à ce que le traitement atteigne le degré désiré.
