Os rolos de pol\u00edmero da Smiley Monroe acabaram de ajudar sua cliente, a Irish Salt Mines (ISME), a alcan\u00e7ar o objetivo de reduzir ainda mais o ru\u00eddo no local de trabalho em uma correia transportadora fechada de alta velocidade em sua unidade de Kilroot, na Irlanda do Norte.<\/p>\n\n\n\n

O transportador do t\u00fanel de recupera\u00e7\u00e3o, com 1200 mm de largura e 120 metros de comprimento, operando a 2,85 m\/s, abrigado em um t\u00fanel de concreto armado abaixo das instala\u00e7\u00f5es de armazenamento das Minas de Sal da Irlanda (Irish Salt Mines), transfere o sal para o transportador de carregamento de navios. Como parte de seus esfor\u00e7os cont\u00ednuos para reduzir o ru\u00eddo no local de trabalho, a ISME pediu \u00e0 Smiley Monroe sugest\u00f5es sobre como isso poderia ser alcan\u00e7ado no t\u00fanel. A Smiley Monroe recomendou a substitui\u00e7\u00e3o dos roletes de a\u00e7o existentes por roletes de pol\u00edmero e, como o cliente j\u00e1 os vinha utilizando com sucesso em seu transportador de carregamento de navios h\u00e1 v\u00e1rios anos, essa medida foi rapidamente implementada.<\/p>\n\n\n\n

Revolu\u00e7\u00e3o Tranquila<\/strong><\/h2>\n\n\n\n

Jason Hopps, agrimensor e oficial de sa\u00fade e seguran\u00e7a da Irish Salt Mines, disse: \u201cEstou muito satisfeito com o desempenho dos rolos de pol\u00edmero da Smiley Monroe, que reduziram significativamente os n\u00edveis de ru\u00eddo em nosso transportador do t\u00fanel de recupera\u00e7\u00e3o. Ap\u00f3s substituir os rolos de retorno e de artesa de a\u00e7o por King Rollers, testes independentes registraram uma redu\u00e7\u00e3o de ru\u00eddo superior a 50%. Agora estamos substituindo ativamente todos os rolos de retorno e de artesa de a\u00e7o restantes neste transportador pelos King Rollers da Smiley Monroe.\u201d<\/p>\n\n\n\n

Chris Jones, Chefe de Suporte de Produto da Smiley Monroe, acrescentou: \u201cOriginalmente recomendamos os Rolos de Pol\u00edmero devido ao seu design robusto, que \u00e9 ideal para lidar com ambientes \u00famidos e corrosivos, como minas de sal, zinco e potassa. Ao contr\u00e1rio de um rolete de a\u00e7o, nosso Rolo de Pol\u00edmero anticorrosivo n\u00e3o enferruja e seus mancais com veda\u00e7\u00e3o em labirinto triplo comprovadamente aumentam a vida \u00fatil. Neste caso, no entanto, foi o benef\u00edcio adicional de um funcionamento mais silencioso que ajudou a resolver o problema de ru\u00eddo no local de trabalho da Irish Salt Mines.\u2019<\/p>\n\n\n\n

Como \u00fanica fornecedora de correias transportadoras e servi\u00e7o de vulcaniza\u00e7\u00e3o no local para a Irish Salt Mines por quase 35 anos, a Smiley Monroe est\u00e1 muito familiarizada com as condi\u00e7\u00f5es severas em que os roletes transportadores de seus clientes operam. A Irish Salt Mines agora est\u00e1 usando os Roletes de Pol\u00edmero da Smiley Monroe em todos os seus transportadores de superf\u00edcie, como guirlandas suspensas, conjuntos de artesa com suporte nas extremidades do tipo encaixe e roletes de retorno.<\/p>\n\n\n\n

Efici\u00eancia Energ\u00e9tica<\/strong><\/h2>\n\n\n\n

Al\u00e9m de uma vida \u00fatil mais longa, maior tempo de opera\u00e7\u00e3o e benef\u00edcios para a sa\u00fade e a seguran\u00e7a, os roletes de pol\u00edmero tamb\u00e9m s\u00e3o 50% mais leves do que um rolo-guia tradicional de a\u00e7o, sendo, portanto, mais f\u00e1ceis de manusear e capazes de reduzir o consumo de energia de uma esteira transportadora em at\u00e9 14%. Em \u00faltima an\u00e1lise, isso ajudar\u00e1 a reduzir as emiss\u00f5es de CO\u2082 da empresa e o custo operacional por tonelada de material produzido. Com os custos cada vez mais elevados de opera\u00e7\u00e3o de instala\u00e7\u00f5es e ve\u00edculos, os roletes de pol\u00edmero podem auxiliar opera\u00e7\u00f5es que consomem muita energia \u2014 desde pedreiras e minas at\u00e9 f\u00e1bricas de cimento \u2014 a tornar suas instala\u00e7\u00f5es mais eficientes em termos energ\u00e9ticos.<\/p>\n\n\n\n

A empresa americana Irish Salt Mining & Exploration Company (I.S.M.E. Co. Ltd) extrai sal-gema para degelo em sua mina de Kilroot, perto de Carrickfergus, na Irlanda do Norte, desde 1965. Produzindo meio milh\u00e3o de toneladas de sal-gema para degelo por ano, a Irish Salt Mines pode atender \u00e0s demandas mais rigorosas nos invernos mais rigorosos. A exporta\u00e7\u00e3o \u00e9 realizada por meio de seu ber\u00e7o de \u00e1guas profundas na margem norte do Belfast Lough, completo com uma esteira transportadora de carregamento de navios que vai diretamente das instala\u00e7\u00f5es de armazenamento no local da mina.<\/p>","protected":false},"excerpt":{"rendered":"
