Abstract

Изобретение относится к устройствам для обогащения и магнитной сепарации полезных ископаемых на горно-обогатительных предприятиях. Сепаратор включает барабан из немагнитного материала, выполненный с возможностью вращения вокруг горизонтальной оси; неподвижную магнитную систему на высокоэнергетичных постоянных магнитах; феррозаполнитель в виде стальных шариков; питатель для подачи исходного материала; узлы подачи промывной и смывной воды; узел регенерации феррозаполнителя; узел загрузки и выгрузки феррозаполнителя; узел сбора и отвода магнитной и немагнитной фракций. Магнитная система имеет угол охвата 160-220° и содержит магнитные блоки, установленные на немагнитной обойме между ферромагнитными концентраторами, образующими полюса магнитной системы и расположенными таким образом, что концентраторы с разной полярностью чередуются в направлении вдоль оси барабана, а между каждой парой последовательно расположенных концентраторов расположен магнитный блок. Магниты в блоках намагничены в направлении, параллельном оси барабана, а их сечение в плоскости, перпендикулярной оси барабана, может иметь прямоугольную, трапецеидальную форму или форму кольцевого сектора. Магнитный поток с концентраторов выводят в рабочую зону сепаратора через реборды на внешней поверхности барабана, выполненные с разрывами по окружности. Технический результат, заключающийся в повышении эффективности извлечения магнитной фракции и снижении энергозатрат, достигнут благодаря конструкции магнитной системы на основе постоянных высокоэнергетичных магнитов, обеспечивающей в рабочей зоне сепаратора высокий уровень высокоградиентных магнитных сил.The invention relates to devices for the enrichment and magnetic separation of minerals in the mining and processing enterprises. The separator includes a drum of non-magnetic material, made with the possibility of rotation around a horizontal axis; stationary magnetic system on high-energy permanent magnets; ferro-filler in the form of steel balls; feeder for feeding the source material; wash and flush water supply units; ferro-filler regeneration unit; unit of loading and unloading ferro-filler; site collection and removal of magnetic and nonmagnetic fractions. The magnetic system has an angle of coverage of 160-220 ° and contains magnetic blocks mounted on a non-magnetic cage between ferromagnetic concentrators that form the poles of the magnetic system and arranged so that concentrators with different polarities alternate in the direction along the axis of the drum, and between each pair of consecutive concentrators located magnetic unit. The magnets in the blocks are magnetized in a direction parallel to the axis of the drum, and their section in a plane perpendicular to the axis of the drum may have a rectangular, trapezoidal shape or the shape of an annular sector. The magnetic flux from the concentrators is brought into the working area of the separator through the flanges on the outer surface of the drum, made with gaps around the circumference. The technical result consists in increasing the efficiency of extracting the magnetic fraction and reducing energy consumption, achieved thanks to the design of the magnetic system based on permanent high-energy magnets, providing a high level of high-gradient magnetic forces in the working area of the separator.
