Rotary Kiln

The dust waste formed during steelmaking in electric arc furnace (EAF) is rich in ferrous and nonferrous metals. Recycling of this dust as a raw material in iron or steel-making is hazardous. EAF dust generated by steel mills contains zinc. The new rotary kiln plant specializes in the recovery of zinc and other metals from this dust. The main product of rotary kiln is Waelz Oxide, also known as Crude Zinc Oxide (CZO). This product is transformed into zinc oxide, zinc sulfate

Silver-white Vermiculite has excellent properties such as thermal insulation, freeze resistance, antibacterial, fire resistance, liquid absorption, soundproof, and so on. When calcined at 800-1000°C for 0.5-1.0 minutes, the volume can rapidly increase by 8-15 times, and even up to 30 times. The specific gravity after the expansion is 50-200kg/m3, the color becomes silvery-white, then loose expanded vermiculite is formed. Silver Expanded Vermiculite is widely used in

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, vermiculite is basically a

Expanded clay (LECA) is a lightweight aggregate manufactured from naturally occurring clay. It is non-toxic, disease free, chemically inert and has a neutral pH. It is used for a variety of applications including; a construction aggregate in lightweight concrete castings, floors and panels and as a loose lightweight fill. It is also used extensively in Green Roof systems as an additive to hydroponic systems as an eco friendly Horticultural Media. Leca is initial letters for:

Calcium aluminate rotary kiln is the equipment mainly for calcining cement clinker. Rotary kiln for calcium aluminate is widely used in cement, metallurgy, chemical industry and other industries. Calcium aluminate is a high-grade raw material for bauxite and limestone kiln. Calcium aluminate does not absorb water and chalk, it does not deteriorate during storage and transportation so does mineral composition and pre-melted aluminum and calcium. Rotary kiln for calcium

Bauxite rotary kiln consists of steel shell, tire, drive gear, kiln hood, kiln seal, burner pipe. Kiln head guard and kiln tail return spoon are built-in block casting, so bauxite rotary kiln has many advantages like easy installation, high heat, corrosion and wear resistance. Kiln head-cold air cover ventilating with cold air makes kiln safer and more reliable by evenly cooling down kiln head, barrel and kiln mouth shield. More stable airflow profits from large volume kiln

Gypsum Rotary Calcination Kiln for New Material Gypsum rotary kiln is an industrial equipment, which can make a lot of production. And the production of gypsum has a great role, mainly used for construction of building engineering, pharmacological treatment, mold processing, chemical industry, cement regulation in many areas, almost became the indispensable in people’s daily life products, so it has a very deep value. Technical Characteristics of Gypsum Rotary Kiln The

5000-20000t/a Magnesium Oxide Production Line Magnesium Oxide Production Line Magnesium Oxide is a granulated magnesium oxide fertiliser, for dry application to the soil. Magnesium Oxide is insoluble. It cannot be used in fertigation programs or in foliar sprays. Magnesium Oxide Production Line Application: Being granular and insoluble, Magnesium Oxide takes time to react in the soil after application and release magnesium in forms available for plant root uptake. It needs to
