1. General equipment for manual sand preparation, concentrator, chemical plant and primary grinding of power system.

2. Special equipment for extracting iron powder from the steel slag. After the steel liquor is discharged from the converter and electric furnace of the steel plant, the steel slag will be self broken into blocks after being treated by the special device for steel slag heating, and then it will be subject to magnetic separation, crushing, secondary magnetic separation, screening, vibrating screen feeding and rod mill for fine grinding to extract useful iron powder, so as to achieve the effect of environmental reuse.
