How to deal with chromium slag?

Chromium slag is a large amount of highly toxic solid waste discharged from chromium salt production plants and ferrochromium alloy production processes. In these solid wastes, in addition to calcium, magnesium, iron, silicon, aluminum and other elements, they also contain certain incompletely reacted Cr2O3, No. 1 to 3 water-soluble sodium chromate and acid-soluble calcium chromate. So how to deal with chromium slag? As a manufacturer of chromium slag vertical grinding mills, Guilin Hongcheng will give you a detailed introduction today.
Utilization of solid waste in steel plants

Utilization of solid waste in steel plants

The solid waste generated by iron and steel enterprises during the production process mainly includes steel slag, blast furnace slag (including water slag, dry slag), iron-containing dust sludge, desulfurization ash, power plant fly ash, waste refractory materials and industrial waste. The utilization of solid waste in steel plants involves many fields such as machinery and equipment, resources, and the environment. As a manufacturer of steel plant vertical mills, Guilin Hongcheng's HLM series of steel plant vertical grinding mills​ provide good equipment assistance for the comprehensive utilization of solid waste in steel plants. Today I would like to introduce to you the current situation of solid waste utilization in steel plants.

How is silicon carbide powder produced?

How is silicon carbide powder produced? Silicon carbide has a very high hardness, with a Mohs hardness of 9.5, a specific gravity of 3.20-3.25, and a hexagonal crystal. For this characteristic, it is more appropriate to choose a silicon carbide Raymond roller mill, which can be used in conjunction with bucket elevators, powder concentrators, etc. form a production line.

Ways to recycle construction waste

The reuse of construction waste has not attracted enough attention, and most of it is transported to rural areas for open dumping or landfill without any treatment. Stacking and landfilling require a large amount of land, garbage removal and other construction funds. At the same time, the dust and dust left during transportation and stacking aggravate environmental pollution. So can construction waste be recycled? What are the ways to recycle construction waste?

How to choose a carbon powder machine

The main raw materials of activated carbon can be almost all carbon-rich organic substances, such as coal, wood, fruit shells, coconut shells, walnut shells, etc. These carbon-containing substances are converted into activated carbon through pyrolysis under high temperature and certain pressure. The activated carbon production line is inseparable from the help of carbon powder making machine. So, How to choose a carbon powder machine?

How to produce steel slag cement?

Steel slag is waste slag produced in steelmaking, generally accounting for 15% to 20% of steel production. Due to the different regions where metal ores are stored, the composition and activity of waste residues discharged after smelting are also greatly different, making the use of metallurgical waste residues somewhat local. Use local steel slag as a mixed material to produce high-quality steel slag cement to reduce environmental pollution from steel slag, reduce cement production costs, improve cement performance, and contribute to the sustainable development of the local economy. So, how to produce steel slag cement?

Vermiculite Grinding Production Equipment

Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperatures. It is a relatively rare mineral and is a silicate. Its crystal structure is monoclinic, and its appearance looks very much like mica. Vermiculite is produced when certain granites are hydrated, and is generally produced at the same time as asbestos. Because vermiculite has the ability to exchange ions, it has a great effect on soil nutrition. During its use, it needs to be crushed with vermiculite grinding production equipment.
Industrial solid waste replaces cement raw materials

Industrial solid waste replaces cement raw materials

Carbon reduction in the cement industry is difficult. How to save energy, reduce consumption and decarbonize the clinker calcination process is a key proposition for the cement industry to achieve low-carbon production. So, can industrial solid waste replace cement raw materials?
