The Steel Slag Rod Mill manufactured by Zhengzhou Zhenggang Machinery Co., Ltd. is a special grinding machine designed for processing and recycling steel slag generated from steelmaking, smelting, converter, electric furnace, and blast furnace operations. It uses steel rods as the grinding medium to crush and grind steel slag through linear contact, helping liberate metallic iron from the slag matrix for subsequent magnetic separation. Compared with conventional ball mills, the rod mill reduces over-grinding, produces more uniform discharge size, improves metal recovery efficiency, and lowers energy consumption. It is widely used in steel plants, slag powder production lines, road base material production, building material processing, and metallurgical residue recovery systems.
The grinding process helps separate metallic iron from steel slag, improving metal recovery and reducing material waste.
Steel rod line-contact grinding produces uniform particle size and reduces over-crushing compared with ball milling.
The rod mill provides fast grinding speed, stable output, and efficient particle reduction for steel slag processing.
Power consumption is lower than conventional ball mills for similar output, helping reduce production cost.
The machine can operate in wet-type or dry-type grinding mode according to process requirements.
Alloy steel liners and heat-treated steel rods provide high toughness, strong abrasion resistance, and long service life.
Used for grinding converter slag, electric furnace slag, blast furnace slag, and other steelmaking residues.
Helps liberate metallic iron from slag before magnetic separation, improving recovery rate and material reuse.
Suitable for producing slag powder used in building materials, cement additives, and industrial applications.
Processes steel slag into uniform particles suitable for road base and construction material preparation.
Applied in ironmaking, steelmaking, ferroalloy, copper slag, nickel slag, and other metallurgical residue treatment lines.
Used to grind and process steel slag into uniform particles for metal recovery, slag powder production, cement additives, road base materials, and construction material recycling.
