Steel slag is an ideal raw material for the production of silicon fertilizer. It has a high total silicon content. The total silicon content in blast furnace slag is 31% ~ 37%. The total silicon content in steelmaking slag (converter slag) is 10% ~ 15%. It is suitable for the production of silicon fertilizer after activation. So, how to produce steel slag silicon fertilizer? Today, Guilin Hongcheng Steel Slag Vertical Grinding Mill manufacturer will analyze and answer for you.

Steel slag has a long history of use in crop production. After the application of steel slag as a fertilizer/soil conditioner, the yield increase effect is obvious; the soil pH adjustment effect is significant; the disease resistance of various crops is enhanced; and the absorption of some harmful elements in the soil by plants is inhibited. The most basic treatment method for producing silicon fertilizer from steel slag is mechanical activation, that is, using a grinding machine to grind the steel slag to increase the fineness of the steel slag, causing changes in the bond energy of the mineral crystals, causing dislocations, defects and recrystallization of the crystal lattice, and surface Form an amorphous structure that is easily soluble in water; by increasing the contact area between minerals and water in steel slag, the interaction between minerals and water is increased, so that water molecules can easily enter the interior of the mineral to accelerate the hydration reaction and improve the activity of steel slag.
Silicon fertilizer produced from steel slag promotes the release of effective elements by increasing the specific surface area of steel slag through mechanical activation. Research results show that as the particle size of steel slag decreases, the phytoavailability of silicon in steel slag shows an increasing trend. The particle size of steel slag Reducing the release of effective elements is beneficial to plants.
The process of producing silicon fertilizer from steel slag basically adopts the process of natural air-drying slag, grinding, sieving and drying. The cost of mechanical activation of silicon fertilizer for steel slag production is generally low. Therefore, in terms of equipment selection, energy saving and consumption reduction should be the main focus. HLM steel slag vertical mill is an advanced energy-saving grinding equipment that integrates drying, grinding, grading and transportation, developed by Guilin Hongcheng after more than 20 years of painstaking research and development. It has high grinding efficiency, low power consumption, The feed granularity is large, the product fineness is easy to adjust, the equipment process is simple, the floor space is small, the noise is low, the dust is small, the use and maintenance are simple, the operating cost is low, and the consumption of wear-resistant materials is low. It meets the requirements of large-scale, intelligent, and Demand for intensive industrial milling.
Using steel slag to produce silicon fertilizer can not only improve soil silicon fertility and increase rice yields, but also solve the problem of steel slag stacking occupying land and causing pollution to the surrounding environment, and at the same time obtain good economic and environmental benefits. Therefore, it can be said that the use of steel slag to produce silicon fertilizer is a promising and alternative way to treat solid by-products; in addition, it can also form a resource utilization link between industrial and agricultural production.
