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 […]

The raw materials for preparing activated carbon are very wide, mainly divided into wood-based and coal-based. Coal-based raw materials mainly include anthracite, coking coal, lignite, petroleum, asphalt and petroleum coke. So, how to choose a coal pulverizer for coal-based activated carbon? Can ordinary coal mill be used for activated carbon preparation? Activated carbon is prepared […]

Raymond mill is a commonly used equipment for ore grinding. How many tons can the Raymond mill produce, that is, how many tons of powder can the Raymond mill grind in one hour? The production capacity of Raymond mill is mainly linked to the machine model and material fineness. How many tons of ore can […]

Bentonite is the most developed and utilized mineral among non-metallic minerals. It has been widely used in oil mining, directional crossing, steel casting, metallurgical pellets, chemical coatings, compound fertilizers, sizing, rubber, plastics, papermaking, water purification, and absorption. Tide agents, pesticides and other fields. Among them, the following six major areas account for a high proportion: […]

During the calcining and dehydration process, the particles of calcined gypsum powder aggregate with each other to produce particle differences. During the calcining process, the process parameters fluctuate within a certain range and the parameters in the calcining furnace are non-uniformly distributed, resulting in uneven performance of the gypsum powder after it is released. The […]

Activated carbon regeneration technology uses physical or chemical methods to remove the adsorbate adsorbed in the pores of activated carbon and restore its adsorption capacity. Activated carbon regeneration technology not only realizes the recycling of resources, but also has little impact on the environment and has good economic feasibility for industrial application. As an activated […]
