Existem quatro classificadores principais:<strong> high-dam single-spiral and double-spiral classifiers and submerged single-spiral and double-spiral classifiers.<\/strong> Introduzi-lo-emos a partir da posi\u00e7\u00e3o da espiral e do n\u00famero de espirais.<\/p>\n<h3><b><\/b>Posi\u00e7\u00e3o da espiral<\/h3>\n<p>O principal componente do classificador espiral \u00e9 a espiral. De acordo com a sua posi\u00e7\u00e3o no tanque e o n\u00edvel da superf\u00edcie da lama, pode ser dividida em tr\u00eas tipos: <strong><b>classificadores espirais de barragem baixa, barragem alta e submersos. <\/b><\/strong>O classificador espiral de barragem baixa \u00e9 raramente utilizado atualmente; os classificadores espirais de barragem alta e submersos s\u00e3o utilizados principalmente.<\/p>\n<h4><b><\/b>1. Classificador espiral de barragem baixa<\/h4>\n<p>Uma vez que atualmente existem poucas aplica\u00e7\u00f5es, segue-se uma breve introdu\u00e7\u00e3o. O tipo de barragem baixa consiste no facto de a barragem de transbordo ser inferior ao eixo do parafuso. Devido \u00e0 pequena \u00e1rea da zona de decanta\u00e7\u00e3o, s\u00f3 pode ser utilizada para lavar min\u00e9rios de areia com pouca lama e desidratar part\u00edculas grosseiras na produ\u00e7\u00e3o atual, mas raramente \u00e9 utilizada em ciclos de moagem.<\/p>\n<h4>2. Classificador espiral de alta barragem<\/h4>\n<p>The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral but lower than the upper edge of the spiral at the overflow end. There are high-dam-type single-spiral and double-spiral classifications. This kind of classifier has a lower settlement area and a larger dam type, and its dam height can be adjusted within a certain range. That is, the area of the settlement area can be adjusted and changed within a certain range so that the particle size of classification can be adjusted, which is an important part and a commonly used device of the grinding cycle. It is mainly used for ore classification with overflow particle size of 0.83mm to 0.15mm.<\/p>\n<h4>3. Classificador espiral submerso<\/h4>\n<p>The submerged type has 4-5 spiral blades at the end of the overflow dam, all submerged in the pulp. There are also two types: <strong>single spiral and double spiral.<\/strong> The classifier has a large settlement area and a deep classification pool, and the spiral agitation has little effect on the surface of the pulp. Hence, the classification surface is stable, and the overflow is large and fine. It is used for ore classification with an overflow particle size of 0.15mm to 0.07mm. The submerged spiral classifier is often used as classification equipment for fine or secondary grinding in <a href=\"https:\/\/www.jxscmachine.com\/pt\/solucoes\/\">mineral processing plants<\/a>.<\/p>\n<p><strong><b>&nbsp;<\/b><\/strong><\/p>\n<h3><b><\/b>N\u00famero de espirais<\/h3>\n<p>Divide os classificadores espirais em <strong><b>de espiral \u00fanica e <\/b><\/strong><strong><b>Classificadores espirais duplex<\/b><\/strong>&nbsp;de acordo com o n\u00famero de espirais. O desempenho de classifica\u00e7\u00e3o dos dois \u00e9 o mesmo, mas o classificador de parafuso duplo tem uma capacidade de processamento maior e \u00e9 adequado para uso com grandes m\u00e1quinas de moagem.
