Resumo: | To achieve micronization in micro and nanoparticle agitator mills are often used. Also used are balls for the grinding step, which are: glass balls, zirconium silicate balls and zirconium oxide balls. A suspension with the active ingredient chlorothalonil at 700 g/L was prepared, being 2 liters for each type of balls. For this, a 1 liter grinding chamber with 0.7 liters of balls was used. The rotation of the mill was set at 2000 rpm and the rotation of the feed pump at 250 rpm. In addition, the temperature of the product, before grinding, was 26°C. The micronization with the glass balls during the process presented the lowest temperature 30°C, but with the lowest flow rate 0.09 L/min and the longest grinding time with 32 minutes. With zirconium silicate balls, the temperature reached was 38°C, the flow rate was 0.15 L/min and the grinding time was 20 minutes. The best result obtained was with the zirconium oxide balls, but with the highest temperature 42°C, but with the highest flow rate 0.19 L/min, and the shortest grinding time with 16 minutes, respectively. When determining the price of kWh consumed by the equipment when using the different types of balls, it was found that, with the zirconium oxide balls, a savings of up to 50% of the electricity consumption is achieved, compared to the use of glass balls. Comparing zirconium silicate balls with glass balls, a 37% savings in consumption is achieved. Finally, with zirconium oxide balls being compared to zirconium silicate, a 25% savings in electricity consumption was obtained. |

También se utilizan esferas para la etapa de molienda, que son: esferas de vidrio, esferas de silicato de circonio y esferas de óxido de circonio. Se preparó una suspensión con el principio activo clorotalonil a 700 g/L, siendo de 2 litros para cada tipo de esferas. Para ello, se utilizó una cámara de molienda de 1 litro con 0,7 litros de bolas. La rotación del molino se fijó en 2000 rpm y la rotación de la bomba de alimentación en 250 rpm. Además, la temperatura del producto, antes de moler, era de 26°C. La micronización con las esferas de vidrio durante el proceso presentó la temperatura más baja 30°C, pero con el caudal más bajo 0.09 L/min y el tiempo de molienda más largo con 32 minutos. Con las esferas de silicato de circonio, la temperatura alcanzada fue de 38°C, el caudal fue de 0,15 L/min y el tiempo de molienda fue de 20 minutos. El mejor resultado obtenido fue con las esferas de óxido de circonio, pero con la temperatura más alta 42°C, pero con el caudal más alto 0.19 L/min, y el menor tiempo de molienda con 16 minutos, respectivamente. Al determinar el precio de los kWh consumidos por los equipos al utilizar los diferentes tipos de esferas, se encontró que, con las esferas de óxido de circonio, se consigue un ahorro de hasta el 50% del consumo eléctrico, en comparación con el uso de esferas de vidrio. Comparando las esferas de silicato de circonio con las esferas de vidrio, se consigue un ahorro del 37% en el consumo. Finalmente, con la comparación de las esferas de óxido de circonio con el silicato de circonio, se obtuvo un ahorro del 25% en el consumo de electricidad.Para alcançar a micronização em micro e nanopartículas moinhos agitadores são frequentemente utilizados. Também são utilizadas esferas para a etapa de moagem, que são: esferas de vidro, esferas de silicato de zircônio e esferas de óxido de zircônio. Uma suspenção com o ingrediente ativo clorotalonil em 700 g/L foi preparada, sendo 2 litros para cada tipo de esferas. Para isso, foi utilizada uma câmara de moagem de 1 litro, com 0,7 litros de esferas. A rotação do moinho foi setada em 2000 rpm e a rotação da bomba de alimentação a 250 rpm. Ademais, a temperatura do produto, antes da moagem, era de 26°C. A micronização com as esferas de vidro durante o processo, apresentou a menor temperatura 30°C, porém com a menor vazão 0,09 L/min e maior tempo de moagem com 32 minutos. Já com as esferas de silicato de zircônio, a temperatura atingida foi de 38°C, a vazão foi de 0,15 L/min e o tempo de moagem foi de 20 minutos. O melhor resultado obtido foi com as esferas de óxido de zircônio, porém com a maior temperatura 42°C, mas com a maior vazão 0,19 L/min, e o menor tempo de moagem com 16 minutos, respectivamente. Ao determinar o preço do kWh consumido pelo equipamento ao usar os diferentes tipos de esferas foi auferido que, com as esferas de óxido de zircônio, alcança-se uma economia de até 50% do consumo de energia elétrica, em comparação com uso das esferas de vidro. Já comparando as esferas de silicato de zircônio com as esferas de vidro consegue-se uma economia de 37% no consumo. Por fim, com as esferas de óxido de zircônio sendo confrontadas as de silicato de zircônio obteve-se uma economia de 25% no consumo de energia elétrica.Research, Society and Development2021-08-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1900710.33448/rsd-v10i10.19007Research, Society and Development; Vol. 10 No. 10; e417101019007Research, Society and Development; Vol. 10 Núm. 10; e417101019007Research, Society and Development; v. 10 n. 10; e4171010190072525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/19007/16995Copyright (c) 2021 José de Freitas Rezende Neto; Antônio Manoel Batista da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRezende Neto, José de FreitasSilva, Antônio Manoel Batista da2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/19007Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:00.340853Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
