Abstract

"DISPOSITIVO PARA GRANULAçãO DE MATERIAL SINTéTICO TERMOPLáSTICO QUE SAI DE BOCAIS". A presente invenção refere-se a um dispositivo para granulação de material sintético termoplástico que sai de bocais, cujos bocais estão previstos em um disco de bocal em um arranjo, em essência, em forma circular, e são tocados por facas que giram em torno de um eixo do suporte das facas, que estão suportadas por um suporte das facas em forma de sino em posição inclinada em relação à direção radial, sendo que o eixo do suporte das facas passa pelo ponto central do arranjo em forma circular, um meio de resfriamento é conduzido ao disco de bocal e às facas para o resfriamento do material granulado, e entre o suporte das facas e o disco de bocal existe um espaço intermediário de forma anular percorrido pelo meio de resfriamento de dentro para fora. O espaço oco (24) do suporte das facas em forma de sino está em ligação com o espaço intermediário, e o meio de resfriamento é conduzido ao espaço intermediário vindo do espaço oco do suporte das facas.
