Beschreibung
Zusammenfassung:	FIELD: mining. ^ SUBSTANCE: invention refers to devices for sizing bulk material, particularly to screens which can be most successfully implemented in mining and building industries. The screen consists of a box with a sieve assembled on spring loaded supports, of an unbalance load and of a gear pair connected to a driven shaft. The unbalance load is made in form of a conic pinion equipped with its own unbalance load and assembled on the shaft installed in bearings of the driven shaft perpendicular to its axis; this conic pinion meshes with another conic pinion rigidly secured on the box coaxially to the driven shaft. ^ EFFECT: upgraded efficiency of screening. ^ 2 dwg
