<p>The device can be used in metallurgy and lime production, in particular in furnace and kiln equipment ensuring even axisymmetrical burden distribution. It includes a vertical mobile cone (1) fitted in the feeding neck of the furnace hopper under which there is an upper cylindrical ring (2) and a lower cylindrical ring (3) fixed to the neck (4) of the furnace under ring (2). The diameter of ring (3) is smaller than the diameter of ring (2). In every ring (2,3) there are groups of inclined flat rejectors (5) evenly radially arranged on its inner side, arranged evenly or step-like in height, the rejectors (5) having rectangular, trapeze-like or step-like form, those having trapeze-like or stel-like form being fitted having their wide sides downwards. In each group the altenrating rejectors (5) have different widths and inclinations. Under cone (1) there is a collection fixed funnel (6) under the hole of which the apex of a fixed spraying cone (7) is fitted. A level (9) passes through a hole on the top of the cone (7), across the neck of funnel (6) and across tube (8) through the top of cone (1) in the lower end of which level (9) wings (10) are fitted pivotly. 1 claim, 2 figures</p> |
