Abstract

Изобретение относится к просеивающим элементам, просеивающим узлам, способам изготовления просеивающих элементов и узлов и способам грохочения материалов для вибрационных грохотов, которые включают в себя использование материалов, полученных литьем под давлением. Использование полученных литьем под давлением ситовых элементов обеспечивает, в том числе, различные конфигурации просеивающих поверхностей; быстрое и относительно простое изготовление ситовых узлов и сочетание превосходных механических и электрических свойств ситового узла, включая прочность, износостойкость и химическую стойкость. Варианты осуществления настоящего изобретения используют термопластичный материал для литья под давлением.The invention relates to screening elements, screening units, methods of making screening elements and units and methods of screening materials for vibrating screens, which include the use of materials obtained by injection molding. The use of sieve elements obtained by injection molding provides, inter alia, various configurations of sieve surfaces; quick and relatively easy fabrication of screen assemblies and a combination of excellent mechanical and electrical properties of the screen assembly, including strength, wear resistance and chemical resistance. Embodiments of the present invention use a thermoplastic injection molding material.
