With the large-scale increase in demand for bauxite, high-quality soil ore has become the object of pursuit. So how many tons of bauxite does 1 ton of alumina need to consume in the production of alumina from bauxite? One ton of alumina consumes 1.85 to 2.6 tons of bauxite, that is, 0.38-0.54 tons of alumina […]

The cement industry encourages the use of non-carbonate raw materials such as calcium carbide slag, paper sludge, desulfurized gypsum, fly ash, metallurgical slag tailings and volcanic ash to replace traditional limestone raw material. So how to use papermaking sludge? What about the processing technology? With the continuous development of society, the monitoring of enterprises’ “waste […]

The new use of attapulgite in fertilizer: in the production process of decomposed chicken manure to make odorless organic fertilizer, adding starter, functional bacteria, attapulgite, etc., not only reduces the The timing and fermentation of fertilizers can also improve the fertilizer efficiency of organic fertilizers, increasing the germination rate of seeds from 70% to more […]

Global consumption will slowly recover in 2022, and the global manganese ore output will reach 58.8 million tons. Manganese is an essential raw material mineral for industrial production, and it is also an important raw material to support the development of emerging industries such as new energy and new materials. At present, with the continuous […]

Steel slag is solid waste discharged from converters, electric furnaces and other equipment in the iron and steel smelting process. The main components are calcium, magnesium, silicon, iron, aluminum, manganese and other oxides, and the emission is about 15-20% of crude steel. It has broad utilization value. Usually, high-specification steel slag vertical mill is used […]

Ceramsite is a light, porous, fine particle material with a certain strength, which is often used in the manufacture of concrete, clay products, filling materials, etc. In the production of ceramsite, raw material crushing is an important process. The raw material is ground to make it into powder, which is completed by ceramsite sand grinding […]
