Steel slag is a by-product of steelmaking. It consists of various oxides oxidized during the smelting process by impurities such as silicon, manganese, phosphorus, and sulfur in pig iron, and salts formed by the reaction of these oxides with solvents. Steel slag contains a variety of useful ingredients: metallic iron 2% -8%, calcium oxide 40% -60%, magnesium oxide 3% -10%, manganese oxide 1% -8%, so it can be used as iron and steel metallurgy raw materials. The use of steel slag also varies depending on the composition. In China, steel slag can be used in various fields such as metallurgical raw materials, road engineering, new building materials engineering, steel slag glass-ceramics, environmental engineering, agriculture, and other fields. It can also produce non-fired bricks, foundry sand, cement expansion agents, and flow control, state sand hardener and so on.
Iron and steel are industrial grains, which are the types of materials that are in high demand in the process of industrial development. Steel, as a core material of iron and steel resources, plays a very important role in its development. Steel slag is the role of steel metal after it is fully utilized. The industrial waste generated belongs to industrial waste. Due to the limited level of science and technology in the past, the substance was discarded. With the continuous increase of human understanding of it, it has a larger application field and is widely used after crushing and processing. In the fields of machinery, metallurgy, industry, chemical industry, etc., and the processing effect can reach the higher satisfaction of users, we will focus on the hardware configuration and process of the steel slag crushing process.
The equipment used in the steel slag crushing production process mainly includes GZG series steel slag vibration feeder, PEY series steel slag special hydraulic protection jaw crusher, GPY series steel slag special hydraulic cone crusher, ZM series steel slag special self-grinding machine, GMBZ series steel slag High efficiency and energy saving rod mill, GMQG series steel slag high efficiency and energy saving ball mill, YKR series steel slag vibrating screen, etc. The following is the equipment configuration for comprehensive recycling of dry steel slag and comprehensive recycling of wet steel slag.
The process of crushing steel slag: First, check whether there is debris or foreign matter in the feeder, and be sure to clean it up, otherwise the purity of the material will be reduced, and then the original steel slag will be transported to the vibration after preliminary filtering. Feeder, this completes the preparation. Secondly, start the equipment, the material of the feeder is fed by the jaw crusher of the vibrating feeder according to the requirements, and then it is coarsely crushed, and then it enters the cone crusher for secondary crushing, so the processed material is finer. User satisfaction will be even greater. If you need to separate slag and steel, the particle size is smaller; you need to use a self-mill, rod mill, ball mill. Finally, the material processed by the crushing equipment enters the vibrating screen for effective screening. This completes the production and processing of the entire process. It should be particularly emphasized that the vibrating screen must be reasonably equipped according to the impurity content of the material, so as to achieve twice the result with half the effect.
Steel slag is a resource that cannot be avoided in the production of steel. The rational use of steel slag can play a role in protecting the environment, increasing economic benefits and sustainable development of resources, which is of great significance to society. The steel slag crushing process has high production efficiency. From the steel slag raw material to the finished product, the processed steel slag is well graded, meets the reuse standards, has good environmental protection performance, and has good cooperation between equipment, which can greatly reduce the investment in equipment maintenance costs.
