Abstract
MÉTODO PARA EVITAR ADESÃO E ENTUPIMENTO DE MATÉRIA-PRIMA MINERAL. A presente invenção refere-se a um método para evitar a adesão e o entupimento com uma matéria-prima mineral no equipamento de transferência e tratamento pela transferência ou tratamento, pelo equipamento de transferência e tratamento, de uma mistura de matérias-primas obtida colocando-se uma resina absorvente de água que atende ao seguinte critério em contato com a matéria-prima mineral, em que, para o critério, a mesma massa de água que a resina absorvente de água é adicionada à resina absorvente de água, uma amostra absorvida pela água após um lapso de 10 minutos é submetida a um teste de peneira vibratória em que a amostra absorvida pela água é passada através de uma peneira vibratória com uma abertura de 9,5 mm e uma frequência de 2800 rpm por 1 minuto, uma razão residual da amostra absorvida pela água na peneira vibratória é obtida pela seguinte fórmula (1), e a razão residual é de 50% em massa ou menos, a razão residual (% em massa) = (uma massa da amostra absorvida pela água na peneira vibratória após o teste de peneira vibratória), (uma massa da amostra absorvida pela água na peneira vibratória antes do teste de peneira vibratória) 100 ... (1).
