Description

лени материала выдел ть посторонние крепкие включени и этим предотвращать возможные поломки рабочих органов (валов-шнеков ).If the material is too lazy to isolate strong foreign impurities and thereby prevent possible breakdowns of the working bodies (screw shafts).

Если дробимым материалом вл етс полезное ископаемое, например уголь, использование этого решени позвол ет одновременно с дроблением производить и обогащение полезного ископаемого.If the material to be crushed is a mineral, for example coal, the use of this solution allows the mineral to be enriched simultaneously with crushing.

Во избежание выхода дробимого мате- риала через концы валов-шнеков вместе с посторонними включени ми длина валов- шнеков должна быть не менее некоторой минимальной величины, завис щей от структуры и влажности материала, угла наклона рамы и максимального размера кусков.In order to avoid the exit of crushed material through the ends of the screw shafts together with extraneous inclusions, the length of the screw shafts must be at least a certain minimum value, depending on the structure and moisture of the material, the angle of the frame and the maximum size of the pieces.

Claims

1. Screw crusher, comprising a housing, crushing elements in the form of shaft-screws installed in two rows and arranged

laid at an acute angle one above the other, and drives of the lower and upper rows of screw shafts, characterized in that, in order to remove foreign impurities during operation, whose strength is higher than the strength of the crushed material, and also to increase reliability and durability, shafts the screws of the upper row are mounted on the housing by means of a frame rotatable in the vertical plane.

2. A crusher according to claim 1, characterized in that the frame is mounted with the possibility of interaction of one of its ends with the housing by means of elastic elements.

3. A crusher according to claim 1, characterized in that, in order to reduce the metal consumption, the drive of the upper row of screw shafts is located on the frame, and the hinge of the rotary frame is mounted on the housing from the loading side of the crusher.
