Abstract
"PROCESSO PARA CARREGAR UMA SUSPENSãO DE SUBSTáNCIA FIBROSA E DISPOSITIVO PARA A EXECUçãO DO PROCESSO". Um processo para carregar uma suspensão de substância fibrosa que contém fibras de celulose com carbonato de cálcio, compreende as seguintes etapas do processo: introdução de hidróxido de cálcio em forma líquida ou seca ou óxido de cálcio na suspensão de substância fibrosa; introdução de dióxido de carbono gasoso na suspensão de substância fibrosa; precipitação de carbonato de cálcio pelo dióxido de carbono; trituração da suspensão de substância fibrosa durante o processo de carregamento e lavagem da suspensão de substância fibrosa após o processo de cristalização e/ou antes do processo de trituração e/ou após o processo de trituração."PROCESS FOR LOADING FIBER SUBSTANCE SUSPENSION AND PROCESSING FOR PROCESSING". A process for loading a fibrous substance suspension containing calcium carbonate cellulose fibers comprises the following process steps: introducing liquid or dry calcium hydroxide or calcium oxide into the fibrous substance suspension; introduction of gaseous carbon dioxide in the fibrous substance suspension; precipitation of calcium carbonate by carbon dioxide; grinding the fibrous substance suspension during the loading and washing process of the fibrous substance suspension after the crystallization process and / or prior to the crushing process and / or after the crushing process.
