摘要:
In the operation, a flux mainly composed of silica ore and a non-ferrous metal-ore raw-material are charged into a smelting furnace via a conveying system.In order to increase the production amount of the metal, the flux is conveyed and treated through a first system, in which the flux is crushed in a ball mill and dried in the ball mill while hot air is blown into the ball mill, and the crushed and dried flux is conveyed directly before the smelting furnace. In the drier of copper concentrate, the flux is not dried at all.
