O moinho de bolas gera ru\u00eddo at\u00e9 cerca de 100 ~ 115dB durante o funcionamento, o que \u00e9 muito prejudicial para o operador e para o ambiente circundante. Como controlar o ru\u00eddo do moinho de bolas<\/strong>? Continue a ler para descobrir.

Qual \u00e9 o ru\u00eddo do moinho de bolas?<\/h2>\n

O ru\u00eddo do moinho de bolas \u00e9 principalmente ru\u00eddo mec\u00e2nico causado pela colis\u00e3o entre a bola de metal no tambor e o revestimento da parede do cilindro e o material processado. A intensidade do ru\u00eddo do moinho de bolas est\u00e1 relacionada com o di\u00e2metro e a velocidade do moinho de bolas, bem como com a natureza e a obstru\u00e7\u00e3o do material. O ru\u00eddo do moinho de bolas \u00e9 basicamente um ru\u00eddo em estado estacion\u00e1rio, com uma ampla faixa de frequ\u00eancia, e os componentes de baixa, m\u00e9dia e alta frequ\u00eancia t\u00eam alta energia sonora. Quanto maior for o di\u00e2metro, mais forte \u00e9 a componente de baixa frequ\u00eancia.

Como reduzir o ru\u00eddo?<\/h2>\n

1) Adicionar uma cobertura de isolamento ac\u00fastico. A estrutura de a\u00e7o \u00e9 adoptada e o moinho de bolas utiliza uma placa de a\u00e7o fina como revestimento exterior. A camada de amortecimento \u00e9 preenchida com l\u00e3 de vidro ultrafina ou outros materiais de absor\u00e7\u00e3o de som para selar todo o moinho de bolas. Como o moinho de bolas gera muito calor durante a opera\u00e7\u00e3o, o moinho de bolas deve prestar aten\u00e7\u00e3o para resolver a dissipa\u00e7\u00e3o de calor no exaustor e facilitar a manuten\u00e7\u00e3o do equipamento.<\/p>\n

(2) Colocar a camada el\u00e1stica. O moinho de bolas coloca um tapete de borracha macia resistente ao calor entre a superf\u00edcie interna do tambor do moinho de bolas e o revestimento. Para evitar o sobreaquecimento do tapete de borracha macia, \u00e9 colocado um feltro industrial com 10-15 mm de espessura entre o revestimento do moinho de bolas e o tapete de borracha macia. O moinho de bolas pode Reduzir o ru\u00eddo do moinho de bolas abaixo do padr\u00e3o permitido.<\/p>\n

(3) O moinho de bolas utiliza um revestimento de borracha em vez de um revestimento de a\u00e7o mangan\u00eas. O n\u00edvel de ru\u00eddo pode ser reduzido em 9dB (A), e as caracter\u00edsticas do espetro de frequ\u00eancia do moinho de bolas tamb\u00e9m s\u00e3o alteradas de alta frequ\u00eancia para baixa frequ\u00eancia. Projeto do moinho de bolas para sala \u00e0 prova de som.<\/p>\n

(4) Se as condi\u00e7\u00f5es o permitirem, centralizar o moinho de bolas numa sala especial para moinhos de bolas e transformar a sala do moinho de bolas numa sala especial de isolamento ac\u00fastico, o efeito ser\u00e1 melhor do que a cobertura de isolamento ac\u00fastico, mas deve prestar aten\u00e7\u00e3o \u00e0 resolu\u00e7\u00e3o do problema de monitoriza\u00e7\u00e3o do funcionamento do moinho de bolas, dissipa\u00e7\u00e3o de calor no interior e manuten\u00e7\u00e3o.<\/p>\n

(5) Colocar uma camada de isolamento ac\u00fastico na parede do tambor. Um feltro industrial de 50 mm de espessura \u00e9 enrolado \u00e0 volta da parede do tambor do moinho, e uma placa de a\u00e7o de 1,5 mm de espessura \u00e9 utilizada como superf\u00edcie de prote\u00e7\u00e3o, e \u00e9 fixada na parede exterior do tambor com parafusos. O valor atual do isolamento ac\u00fastico \u00e9 de cerca de 12dB (A). Se as duas extremidades do tambor tamb\u00e9m forem tratadas da mesma forma, as juntas envolvidas na parede do tambor s\u00e3o seladas e o efeito de isolamento ac\u00fastico pode ser melhorado.<\/p>\n
