Steel plant slag treatment equipment

Steel plant slag treatment equipment

The slag produced in the process of steel plant production is a common Industrial waste. If it is not treated, it will cause serious pollution to the environment. Therefore, the research and application of slag treatment equipment in steel mills has become an important environmental protection field.

1、 Classification of slag treatment equipment in steel mills

The slag treatment equipment in steel mills is mainly divided into two categories: physical treatment equipment and chemical treatment equipment. Physical processing equipment includes magnetic separators, heavy medium concentrators, vibrating screens, etc., while chemical processing equipment includes cement production lines, calcium silicate production lines, etc.

2、 Use of physical processing equipment

1. Magnetic separator

A magnetic separator is a device that uses magnetic differences to separate minerals. In the treatment of slag in steel mills, magnetic separators can separate iron minerals from the slag, thereby achieving the goal of recycling iron resources. At the same time, the magnetic separator can also separate other useful metal minerals, such as copper, lead, zinc, etc.

2. Heavy medium concentrator

The heavy medium concentrator is a kind of equipment that uses density difference to separate minerals. In the treatment of steel plant slag, the heavy medium concentrator can separate the heavy minerals from the slag, thereby achieving the goal of recycling metal resources. At the same time, the heavy medium concentrator can also separate other useful non-metallic minerals, such as quartz and bentonite.

3. Vibration screen

A vibrating screen is a device that uses vibration to screen granular materials. In steel plant slag treatment, vibrating screens can screen large particles of material in the slag, thereby achieving the goal of reducing the volume of the slag. At the same time, the vibrating screen can also separate some useful granular materials in the slag, such as limestone, quartz, etc.

3、 Use of chemical treatment equipment

1. Cement production line

A cement production line is an equipment that utilizes components such as silicon, aluminum, and iron in slag to produce cement. In the treatment of slag in steel mills, the cement production line can recover the useful components in the slag, thereby achieving the goal of reducing the volume of slag and recycling resources.

2. Calcium silicate production line

The calcium silicate production line is an equipment that utilizes calcium, silicon, and other components in slag to produce calcium silicate. In the treatment of slag in steel mills, the calcium silicate production line can recover useful components from the slag, thereby achieving the goal of reducing slag volume and recycling resources.

4、 Advantages of slag treatment equipment in steel mills

1. Environmental protection

The development and application of slag treatment equipment in steel mills can effectively reduce the environmental pollution caused by slag generated during production, and protect the ecological environment.

2. Recycling resources

Steel plant slag treatment equipment can recover useful components from slag, such as iron, copper, lead, zinc, and other metal resources, thereby achieving the goal of resource conservation.

3. Improving economic benefits

The application of slag treatment equipment in steel mills can improve their economic benefits, such as recycling metal resources, producing cement, calcium silicate, etc.

5、 Summary

The slag treatment equipment in steel mills is one of the important equipment in the steel industry. Its application can effectively reduce the environmental pollution caused by the slag generated in the production process of steel mills, recover resources, and improve economic benefits. In the future, with the continuous improvement of environmental awareness, the application of slag treatment equipment in steel mills will become increasingly widespread.
