Abstract

"APARELHO PARA AQUECIMENTO DE MATERIAL FLUIDO CONTENDO SóLIDOS". A presente invenção se refere a um aparelho para o aquecimento de material fluido (fluente, que flui) contendo sólidos finamente divididos, tal como lama concentrada (pasta fluida, mistura aquosa de matéria insolúvel) contendo metais preciosos e/ou minerais preciosos, até em uma faixa de temperatura desejada, por exemplo, a faixa de temperatura aplicada em um processo de tratamento de referido material, referido aparelho compreendendo recursos para alimentação e remoção do meio utilizado para aquecimento bem como recursos para alimentação e remoção do material a ser aquecido dentro e fora do aparelho. Em concordância com a presente invenção, ambos o espaço de fluência do material a ser aquecido e os canais de fluxo (3) do meio de aquecimento são instalados em uma posição essencialmente vertical, de maneira que o material a ser aquecido pode ser alimentado para a parte de fundo do espaço de fluência, e o meio de aquecimento pode ser alimentado para a parte de topo dos canais de fluxo (3), e de que na câmara de alimentação (5) do material a ser aquecido, são instalados recursos (9) para limpeza da câmara de alimentação (5).
