Abstract

MÉTODO DE TRATAMENTO DE MATERIAL A GRANEL CONTENDO UMIDADE E DISPOSITIVO DE ADIÇÃO DE FLOCULANTE. Um método é proporcionado que, mesmo quando se adiciona continuamente um floculante polimérico ao material a granel contendo umidade transportado em uma esteira transportadora, permite utilizar equipamento mais simples para adicionar de forma mais uniforme o floculante polimérico ao material a granel contendo umidade. Este método de tratamento de material a granel contendo umidade, que envolve a adição de um floculante ao material a granel contendo umidade transportado em uma esteira transportadora, envolve: usar, como o floculante acima mencionado, uma dispersão líquida que contém um floculante polimérico em uma solução salina em um estado disperso; usar um elemento em forma tubular instalado acima da esteira transportadora e com saídas que são proporcionadas na parede periférica ao longo da direção do eixo longo e que deixam a dispersão líquida fluir na direção da largura da esteira transportadora; e adicionar a dispersão líquida a partir das saídas no elemento em forma tubular ao material a granel contendo umidade na esteira transportadora.METHOD OF TREATMENT OF BULK MATERIAL CONTAINING MOISTURE AND FLOCULANT ADDITION DEVICE. A method is provided which, even when continuously adding a polymeric flocculant to moisture-containing bulk material transported on a conveyor belt, allows simpler equipment to be used to more uniformly add the polymeric flocculant to the moisture-containing bulk material. This method of treating moisture-containing bulk material, which involves adding a flocculant to moisture-containing bulk material transported on a conveyor belt, involves: using, like the above-mentioned flocculant, a liquid dispersion containing a polymeric flocculant in a saline in a dispersed state; using a tubular shaped element installed above the conveyor belt and with outlets which are provided in the peripheral wall along the long axis direction and which let the liquid dispersion flow in the width direction of the conveyor belt; and adding the liquid dispersion from the outlets in the tube-shaped element to the moisture-containing bulk material on the conveyor belt.
