Abstract

Чтобы создать компактное просеивающее устройство для просеивания сыпучего материала со статическим каскадным просеивателем в качестве предварительного просеивателя, который установлен внутри корпуса просеивателя (10) и после которого, при необходимости, устанавливают дополнительный просеиватель в качестве добавочного просеивателя, согласно изобретению предлагается использовать в качестве каскадного просеивателя два ряда конусных колец, которые во всех случаях установлены на расстоянии друг от друга, одно над другим и концентрично по отношению к друг другу, точнее, из ряда внешних по радиусу конусных колец (11) и ряда внутренних по радиусу конусных колец (12) для просеивающего потока, и создать зону просеивания (13), образующуюся между внешним и внутренним по радиусу рядом колец и имеющую форму, например, усеченного конуса, при этом больший диаметр зоны просеивания находится в верхней части, а меньший диаметр зоны просеивания находится в нижней части рядов колец, выполнить множество отверстий для загрузки просеиваемого материала (14а, 14b и т.д.), распределенных по окружности в верхней части зоны просеивания (13) статического каскадного просеивателя, имеющей больший диаметр (D). Согласно изобретению, помимо прочего, такое просеивающее устройство встроено в размольную линию, имеющую мельницу и просеиватель.In order to create a compact screening device for screening granular material with a static cascade screener as a preliminary screener, which is installed inside the screener body (10) and after which, if necessary, an additional screener is installed as an additional screener, according to the invention, it is proposed to use two as a cascade screener a series of conical rings, which in all cases are installed at a distance from each other, one above the other and concentric in relation to each other, more precisely, from a number of cone rings external in radius (11) and a number of cone rings internal in radius (12) for a screening flow, and to create a screening zone (13) formed between the outer and inner radius groups of the rings and having a shape, for example, of a truncated cone, with a larger diameter of the sieving zone located in the upper part, and a smaller diameter of the sieving zone located in the lower part of the rows of rings, to make many holes for loading the sifted material (14a, 14b, etc.) distributed around the circumference in the upper part of the sieving zone (13) of the static cascade sifter having a larger diameter (D). According to the invention, among other things, such a screening device is integrated in a grinding line having a mill and a screener.
