Steel Slag Processing Plant Equipment Selection
With the continuous development of the machine-made sand industry, it develops various solutions for waste resources. The steel slag waste after various mechanical equipment processes will be reused in multiple industries, directly turning it into treasure. For example, the steel industry produces a large amount of steel slag during the steel-making process, which may seem like a waste to outsiders, but in the eyes of stone workers, it is a treasure. Steel slag contains many trace elements. After the process, It has wide applications. Here is the introduction to the uses of steel slag in detail.
Usage of Waste Steel Slag
- Mixed with asphalt concrete for road construction. Steel slag is wear-resistant and corrosion-resistant and has a high hardness and rough surface. Therefore, after processing the raw material to about 15 to 25 millimeters, mix it into asphalt concrete for paving. This steel slag concrete material has high-temperature stability and low-temperature crack resistance, so its service life is much longer than ordinary asphalt concrete.
- Cement production for building materials. The formation temperature of steel slag is relatively high, generally above 1500 ℃, and it crystallizes tightly with a slower hydration rate. Therefore, steel slag cement will add an amount of gypsum and other admixtures to get a higher-strength product than ordinary cement. When used in construction materials, it can improve its crack resistance.
- Add blast furnace slag and other materials to make building bricks. Due to the higher hardness and better wear resistance of steel slag compared to other building aggregates, bricks made from steel slag also have the characteristics of good wear resistance and high strength.
- In addition, the processed steel slag can regulate soil PH and improve the environment. Make sintering solvents to increase sintering production capacity, etc.
Steel slag processing plant flow
After introducing the use of steel slag, here is the process of steel slag:
- Steel slag uniformly enters the jaw crusher through a vibrating feeder for coarse crushing treatment. After coarse crushing, the steel slag enters the vibrating screen for screening into materials of different particle sizes. If it does not meet the particle size requirements, the materials will return to the crusher machine for crushing.
- The material that meets the particle size requirements (about 10cm) enters a hydraulic cone crusher for intermediate and fine-crushing treatment. It also needs to go through vibrating screening equipment for screening. The material around 2cm directly enters the next stage, while those materials larger than 2cm return to the cone crusher for crushing. The next stage mainly depends on actual needs. If the required finished product is gravel, it will enter the magnetic separator for the iron removal process.
- If it requires fine powder, the material will enter the ball mill for grinding treatment. After the particle size meets the requirements, it will go through a magnetic separator for magnetic separation and get the final product.
- The price of processed steel slag powder is relatively higher, and it is the source of profit for the complete steel slag processing plant. The iron powder has a lower selling price with a larger quantity. Brick factories and cement plants will need the iron powder and purchase it. The crushing processing and reuse of steel slag are profitable and have a protective effect on the environment, so the recycling and utilization of steel slag are strongly supported and have a promising future.
Steel slag processing plant equipment
Jaw crusher
It is suitable for processing large steel slag materials (feed particle size ≤ 1200mm). It uses the principle of squeeze crushing, combined with a deep V-shaped and dead zone-free crushing chamber. There is no need to worry about material blockage. It uses wedge blocks to adjust the discharge port and reduce the labor intensity of workers and downtime. It is suitable for ores and rocks medium and fine crushing with compressive strength not exceeding 280MPa, especially for high-hardness and strongly corrosive materials. Its production range is 1-1000t/h.
Cone crusher
The cone crusher is widely used for the intermediate crushing processing of steel slag and adopts the laminated crushing method. The rolling mortar wall moves towards the crushing wall to squeeze materials.
Through hydraulic motor to adjust the discharge port, which is convenient and equipped with remote touchscreen operation to achieve safety operation.
A high-performance stone crusher is for the second and third-stage crushing processes of metal mines and construction sand and gravel processing. Due to its strong crushing capacity and large output, it is widely used for crushing medium-hard materials.
Impact crusher
The impact crusher is widely used in highway construction, water conservancy engineering, construction gravel, machine sand processing, and other fields for coarse crushing, medium crushing, and fine crushing operations of various soft and medium hard ores.
Ball mill
Steel slag belongs to a type of industrial waste. If not properly utilized, it will inevitably cause environmental pollution. The most suitable equipment for processing this mine is the ball mill. Steel slag through grinding can save energy and equipment costs, and the ball mill has good grinding ability and low overall energy consumption. Therefore, the common steel slag grinding equipment is steel slag ball mills.
Magnetic separator
The purpose of the steel slag process is to recover useful iron-containing components, including bulk iron, granular iron, and fine iron tetroxide. Due to the strong magnetism of the above components, the process of steel slag beneficiation is magnetic beneficiation, and the required equipment is a magnetic separator. The magnetic separation of steel slag includes dry-magnetic separation and wet-magnetic separation. Dry magnetic separation mainly recovers large blocks of iron, while wet magnetic separation recovers granular iron and iron tetroxide.
