Abstract

The plant for producing metallic pellets from a salt-added magnesium or alloys thereof comprises a metal-melting furnace, a centrifugal pelletizer with a perforated bowl and a cylindrical pellet-collecting chamber. A hopper is provided in said cylindrical chamber to divide the latter into two concentric zones open from below, of which one zone is adapted for collecting salvage resulting from the pellet formation process, while the other zone is for pellet collection. Provision of said zones makes it possible to considerably reduce the content of salts in magnesium pellets or in those of alloys thereof, as a great proportion of the salts get into the hopper and is withdrawn from the chamber as process waste, whereas the magnesium pellets settle down in the other zone and are then forwarded for further processing.

Claims3

Dependent claims

A plant for producing metallic pellets from a salt-added magnesium or alloys thereof, comprising:

a furnace for melting a salt-added metal;
a centrifugal pelletizer with a perforated bowl;
a means for feeding the molten metal together with the salt additive to said centrifugal pelletizer;
a cylindrical chamber accommodating the perforated bowl of said centrifugal pelletizer and adapted for collecting the pellets formed from the molten metal when the latter is shot out through the perforations in said bowl;
a hopper provided in said cylindrical chamber under the coaxially with the perforated bowl;
said hopper dividing said cylindrical chamber into two concentric zones open from below, of which one zone established by said hopper is located centrally in said chamber and is adapted for collecting salvage that results from the pellet formation process, while the other annular-shaped zone is located along the periphery of said chamber and is adapted for pellet collection;
a pellet withdrawal mechanism provided under said latter zone;
a salvage disposal mechanism provided under said former zone.
