Design of Blast Furnace Slag Treatment System
Introduction
Blast furnace slag is a by-product of blast furnace iron production. It consists of nonmetallic components such as silicates and aluminates of calcium, magnesium, iron and other trace elements. The physical and chemical properties of the slag vary depending on the conditions under which the iron was produced. Blast furnace slag has been processed for use in many different ways. It can be used in its raw form, as a topping on roads, or it can be further processed into a cement-like material. The amount of slag produced by blast furnaces has steadily increased over the years, creating a need for efficient slag treatment systems. This paper outlines the design and operation of a blast furnace slag treatment system.
System Design
A blast furnace slag treatment system consists of two main components: a slag silo and a slag processor. The slag silo is used to collect the slag from the blast furnace. It is then conveyed to the slag processor, which is designed to break down the slag into smaller pieces. The pieces can then be further processed into usable materials such as a cement-like product.
The first step in the process is to collect the slag from the blast furnace via the slag silo. The slag silo is typically an enclosed structure where the slag is stored. Once the slag is collected, it is then conveyed to the slag processor. The slag processor consists of several components, such as a hammer mill, an impact crusher, and a sizer. The hammer mill is used to break down the slag into smaller pieces, while the impact crusher is used to break down the pieces further. The sizer is used to separate the materials according to particle size.
Operation
Once the slag has been collected in the slag silo and conveyed to the slag processor, it is ready for further processing. The hammer mill is used to break down the slag into smaller pieces, which are then further fragmented by the impact crusher. The final material is then sorted by the sizer and can be further processed into a cement-like product.
Conclusion
A blast furnace slag treatment system is a necessary component of an efficient blast furnace iron production operation. The system consists of a slag silo and slag processor, which work together to collect, sort, and process the slag. The processed slag can then be further processed into useful materials such as cement-like products. This paper has outlined the design and operation of a blast furnace slag treatment system.
