Steel slag is a waste residue generated by the steel industry. After undergoing processes such as crushing, magnetic separation, drying, and grinding, it gains significant value for utilization. The recycling and utilization of steel slag not only create economic benefits but also help eliminate environmental pollution. There are two main pathways for the comprehensive utilization of steel slag as a secondary resource. One is its use as a smelting solvent for internal recycling in the plant, which can replace limestone and recover a large amount of metallic iron and other useful elements. The other pathway involves using steel slag as raw material for manufacturing road materials, construction materials, or agricultural fertilizers.
DaHua Heavy Machinery has undertaken the EPC steel slag comprehensive recycling and utilization project for a steel plant in Xingtai, Hebei Province, with an annual output of 150,000 tons. The main equipment in the production line includes the PEY series hydraulic protection jaw crusher for steel slag, the GMBZ series efficient and energy-saving rod mill for steel slag, the 2YKR series vibrating screen, and the steel slag-specific magnetic separator, among other related main and supporting equipment.
PEY series hydraulic protection jaw crusher for steel slag:
The machine allows for setting the rated load arbitrarily, enabling selective crushing of materials with different compressive strengths.
It provides reliable protection and automatically discharges unbreakable materials, effectively solving the issue of "steel jamming" during steel slag crushing.
It automatically resets after iron removal, enabling continuous production without stopping the machine.
Supported by a single hydraulic cylinder under the hydraulic station, it can adjust the discharge opening size and unload unbreakable materials.
It comes with a built-in hydraulic station and a PLC automatic control system.
GMBZ series efficient and energy-saving rod mill for steel slag:
The special discharge structure and environmental protection measures ensure uniform and large discharge volume with low pollution.
The specially designed feeder provides a large feeding capacity. The equipment is equipped with auxiliary devices such as a slow-speed drive device and a dry oil injection device, which can also be customized and manufactured according to user requirements.
It has a high crushing ratio and achieves good purification effects.
It is supported by rolling bearings, resulting in 10-20% energy savings.
The equipment is easy to operate and has a stable and reliable structure.
