Abstract

FIELD: concentration of minerals, in particular, density separation of granular materials in coal and other industries. SUBSTANCE: apparatus has channel with upper wall inclined relative to channel bottom toward product discharge direction, and discharge device formed as chamber with transverse walls submerged into the channel for different depths. Chamber is widened from bottom to the top, with widening value being determined from expression: h < 0.5 - 0.6 (l - a), where l is apparatus channel length; a is chamber size in the direction of flow of separating medium. EFFECT: increased efficiency, improved quality of separation product by intensified process and optimized charging conditions. 4 cl, 2 dwg

Изобретение относится к обогащению полезных ископаемых, преимущественно для разделения зернистых материалов по плотности, и может быть использовано в угольной и других отраслях промышленности. Сущность изобретения: в устройстве для противоточного гравитационного обогащения полезных ископаемых верхняя стенка канала выполнена с наклоном относительно дна канала в сторону выгрузки продукта, а загрузочное приспособление выполнено в виде камеры, поперечные стенки которой погружены в канал на разную глубину, камера выполнена расширяющейся по высоте от дна канала. Предлагаемое изобретение позволяет улучшить качество продуктов разделения за счет интенсификации процесса и создания оптимальных условий загрузки.The invention relates to mineral processing, mainly for the separation of granular materials by density, and can be used in coal and other industries. The inventive device for countercurrent gravitational enrichment of minerals the upper wall of the channel is made with an inclination relative to the bottom of the channel towards the discharge side of the product, and the loading device is made in the form of a chamber, the transverse walls of which are immersed in the channel at different depths, the chamber is expanding in height from the bottom channel. The present invention allows to improve the quality of separation products due to the intensification of the process and the creation of optimal loading conditions.
