O que \u00e9 um crivo de desidrata\u00e7\u00e3o? Que tipos de crivos de desidrata\u00e7\u00e3o existem?<\/b><\/h2>\n

 <\/p>\n

O ecr\u00e3 de desidrata\u00e7\u00e3o<\/a> \u00e9 utilizado principalmente para desidrata\u00e7\u00e3o, deslamagem e degrada\u00e7\u00e3o. Pode ser utilizado para lavagem de areia em instala\u00e7\u00f5es de areia e gravilha, recupera\u00e7\u00e3o de lamas de carv\u00e3o em instala\u00e7\u00f5es de prepara\u00e7\u00e3o de carv\u00e3o, ou rejeitos secos de concentradores, etc., pelo que tamb\u00e9m \u00e9 designado por crivo de desidrata\u00e7\u00e3o de areia e crivos de desidrata\u00e7\u00e3o de minas, crivos de desidrata\u00e7\u00e3o de lamas, crivos de desidrata\u00e7\u00e3o de rejeitos, crivos de desidrata\u00e7\u00e3o de alta frequ\u00eancia, etc.<\/span><\/p>\n

 <\/p>\n

Quais s\u00e3o os equipamentos de lavagem de areia normalmente utilizados?<\/b><\/h2>\n

\"Ecr\u00e3<\/span><\/p>\n

De um modo geral, o equipamento de lavagem de areia normalmente utilizado inclui m\u00e1quina de lavar areia em espiral<\/a>M\u00e1quina de lavar areia com impulsor (m\u00e1quina de lavar areia com rodas), e peneira vibrat\u00f3ria de desidrata\u00e7\u00e3o. Essas tr\u00eas m\u00e1quinas de lavar areia s\u00e3o usadas principalmente em ind\u00fastrias como pedreira de areia, minera\u00e7\u00e3o, constru\u00e7\u00e3o e materiais de constru\u00e7\u00e3o, ind\u00fastria qu\u00edmica e esta\u00e7\u00e3o de mistura de concreto. H\u00e1 tr\u00eas fun\u00e7\u00f5es principais dessas m\u00e1quinas: <\/span>Lavagem<\/b>, <\/span>Classifica\u00e7\u00e3o<\/b>e <\/span>Desidrata\u00e7\u00e3o<\/b>.<\/span><\/p>\n

 <\/p>\n

Entre esses ecr\u00e3s de desidrata\u00e7\u00e3o. Quais s\u00e3o as diferen\u00e7as entre o crivo de desidrata\u00e7\u00e3o de areia e o crivo de desidrata\u00e7\u00e3o de rejeitos?<\/b><\/h2>\n

 <\/p>\n

Embora ambos perten\u00e7am ao equipamento de desidrata\u00e7\u00e3o, a estrutura do ecr\u00e3 de desidrata\u00e7\u00e3o \u00e9 diferente, bem como o material de processamento adequado. Por exemplo, o crivo de desidrata\u00e7\u00e3o de areia na linha de produ\u00e7\u00e3o de lavagem de areia e o crivo de desidrata\u00e7\u00e3o de rejeitos normalmente utilizado em concentradores s\u00e3o equipamentos diferentes. \u00c9 principalmente utilizado na linha de produ\u00e7\u00e3o de areia h\u00famida e utilizado com a m\u00e1quina de lavar areia, ou pode ser utilizado sozinho.<\/span><\/p>\n

 <\/p>\n

Porque \u00e9 que um crivo de desidrata\u00e7\u00e3o deve ser equipado com uma m\u00e1quina de lavar areia?<\/b><\/h2>\n

 <\/p>\n

Porque \u00e9 que os dois devem ser utilizados em conjunto? \u00c9 preciso saber que a areia lavada pela m\u00e1quina de lavar areia n\u00e3o \u00e9 muito limpa. A areia tem um grande teor de lama e \u00e9 demasiado h\u00famida (elevado teor de \u00e1gua), o que n\u00e3o satisfaz os requisitos de produ\u00e7\u00e3o da norma relativa ao teor de lama da areia, pelo que \u00e9 necess\u00e1rio um crivo de desidrata\u00e7\u00e3o. A areia e o cascalho s\u00e3o limpos por uma m\u00e1quina de lavagem de areia e, em seguida, submetidos a uma segunda lavagem com \u00e1gua, classifica\u00e7\u00e3o hidr\u00e1ulica, deslamagem e desidrata\u00e7\u00e3o atrav\u00e9s de um crivo de desidrata\u00e7\u00e3o para atingir uma rela\u00e7\u00e3o de tamanho de part\u00edcula razo\u00e1vel e reduzir o teor de lama para menos de 0,7%.<\/span><\/p>\n

 <\/p>\n

O crivo de desidrata\u00e7\u00e3o pode ser utilizado sozinho?<\/b><\/h2>\n

 <\/p>\n

O crivo de desidrata\u00e7\u00e3o tamb\u00e9m pode ser utilizado sozinho quando \u00e9 utilizado para alguns materiais com baixo teor de lama. N\u00e3o \u00e9 necess\u00e1ria uma m\u00e1quina de lavar areia, como a areia de quartzo. Como a areia de quartzo geralmente cont\u00e9m baixo teor de lama, usar uma m\u00e1quina de lavar areia para lavar areia n\u00e3o s\u00f3 consome energia, mas tamb\u00e9m \u00e9 eficaz Pobre, o importante \u00e9 que o custo de investimento da tela de desidrata\u00e7\u00e3o \u00e9 menor do que o da m\u00e1quina de lavar areia<\/a>.<\/span><\/p>\n

 <\/p>\n

Quais s\u00e3o as pe\u00e7as de desgaste do crivo de desidrata\u00e7\u00e3o e se s\u00e3o substitu\u00eddas frequentemente?<\/b><\/h2>\n

 <\/p>\n

N\u00e3o existem muitas pe\u00e7as vulner\u00e1veis no crivo de desidrata\u00e7\u00e3o, normalmente as pe\u00e7as de desgaste s\u00e3o os crivos, os motores de vibra\u00e7\u00e3o, etc. A frequ\u00eancia de substitui\u00e7\u00e3o tem de ser determinada de acordo com a situa\u00e7\u00e3o real do utilizador, que pode variar muito.<\/span><\/p>\n
