Dedusting Ash Binder is a patented new-type industrial special binder designed for industrial solid wastes generated in iron and steel plants, metallurgical plants and sintering plants, including dedusting ash, steel slag dust and smelting sludge. It thoroughly solves the common drawbacks of traditional binders, such as poor adaptability, easy breakage after molding and insufficient stability. Conventional binders only provide basic bonding effects and cannot address the unique properties of high-content active calcium oxide in dedusting ash. Calcium oxide undergoes intense hydration upon contact with water, leading to a volume expansion of 1.5 to 2.5 times. This easily causes cracking, collapsing and pulverization of pressed briquettes, significantly reducing the recycling rate of dedusting ash, wasting resources and causing secondary dust pollution in factory areas.
The core innovation of this product lies in its exclusive anti-oxidation calcium active ingredients. These ingredients actively trigger complexation and curing reactions with unhydrated and incompletely hydrated active calcium oxide in dedusting ash, converting unstable free calcium oxide into densely structured, highly stable cured crystals. This fundamentally prevents structural damage caused by calcium oxide hydration and expansion and guarantees the structural integrity of briquettes. Adopting an eco-friendly inorganic composite formula, the product contains no harmful volatile substances, produces no peculiar odors and causes no pollution, fully complying with industrial green production standards. Meanwhile, it is classified into non-drying and drying types according to differentiated industrial production needs to adapt to diverse production line configurations.
The non-drying type of Dedusting Ash Binder is applicable to small and medium-sized production lines without drying equipment. It cures naturally at room temperature without thermal drying, lowering equipment investment and energy consumption. The drying type is tailored for large automated drying production lines, offering faster curing speed, higher molding strength and suitability for large-scale continuous production. The product features superior universality and compatibility with various complex dedusting ash containing iron, calcium, zinc and other elements. It adapts to mainstream processes including cold-press molding and mechanical ball pressing, with a dosage of merely 1% to 5% of the total material weight, delivering low consumption and high cost performance. Molded briquettes cure quickly and reach qualified service strength after short-term room-temperature standing, resisting damage during storage, transportation and furnace recharging. Fully compliant with all technical indicators for metallurgical furnace recycling, it is currently a core specialized material for the resource utilization of industrial dedusting ash.
