Cold-solidified briquetting is the main method for steelmaking sludge treatment in metallurgical enterprises at present.

Metallurgical ore powder briquette is a new type of furnace charge introduced in recent years. Because of its environmental protection and energy-saving characteristics in the production and use process, it is widely used in iron and steel, and ferroalloy enterprises instead of lump ore for smelting. The preparation of metallurgical pellets is an important part of the metallurgical process, which can not only improve the metallurgical physical and chemical properties of materials but also realize the resource utilization of industrial solid waste and an important way of the circular economy. Therefore, pelletizing technology is an important way to realize energy saving, environmental protection, and utilization of waste resources. The cold-pressed pellets prepared by this technology are also used as a burden for blast furnaces, direct reduction furnaces, cupola furnaces, and submerged arc furnaces.

In order to make the large and medium-sized ferroalloy reduction electric furnace run better, it is required that the burden should have proper fragmentation and ensure good air permeability. At present, the supply of high-quality lumpy burdens which can be directly used in the furnace is becoming increasingly tight. In order to adapt to this situation, some manufacturers adopt various lumping technologies and use fine ore and concentrate to obtain better smelting indexes. Among them, high-pressure briquette machine pelletizing technology has become a new development direction of ferroalloy pelletizing technology in recent years because of its simple process, fuel-saving, applicability to fine ore, and a wide variety.

"Cold-solidified briquettes" made by high-pressure briquetting machine using sludge, dust removal ash, and iron scale produced by steelmaking as raw materials, adding lime, and using organic glue as a binder.

For briquetting equipment, roller skin is one of the key parts and plays an important role in the equipment performance. The life of the roller skin determines the service time of the briquette machine, and the roller skin is also a vulnerable part of the briquette machine. Therefore, before making a purchase, it is important to carefully check the roller skin of the briquette machine, which can not only ensure the quality of the briquetting equipment but also reduce the equipment cost and improve the economic benefits.

The compressive strength of different kinds of dried sludge briquette also has obvious differences with the different addition ratios. This product is generally used for the treatment of mine, wastewater sludge and medical sludge. The main reason is that the different composition of sludge itself will also cause the difference of its cohesiveness, which is generally manifested in the difference of water content, inorganic matter and component. Organic components in medical sewage sludge mainly include: Protein, sugar, lipid and a large number of reproductive bacteria and parasites, etc.The organic components of domestic wastewater sludge and brewery wastewater sludge contain not only proteins, sugars, bacteria and parasites, but also some fibrous organic compounds, among which brewery wastewater sludge has high content of fibrous organic compounds. The research on the preparation of biomass briquette​ in Tsinghua University found that for long fibrous biomass, biomass forms a network in the briquette forming process. In a certain range, with the increase of screening, the fiber length increases, the crosslinking between biomass increases, and its forming rate increases. However, for granular biomass, there is basically no crosslinking between biomass, and it is difficult to form a reticular connection.

Ore Powder Briquette Machine Ore powder briquette machine mainly presses all kinds of iron powder, ore powder, iron scale, steel slag, refractory, etc. All materials with powder to be fired need an ore powder briquette machine. The ore powder briquette machine produced by Kaizheng Company is reliable in quality, multi-purpose and high in pressure intensity, which is suitable for large, medium, and small enterprises with fixed production scale production lines. It is suitable for industrial gasification, boiler type, cold press type focus, ignition briquette, civil briquette, civil metallurgy, refractory, medicine, and other materials. After years of industrial use and improvement, compared with other similar products, the ore powder briquette machine has obvious advantages such as high ball forming rate, low power consumption, compact structure, and convenient maintenance and debugging.

When we buy briquetting equipment, we should not only consider the quality of briquette machine itself, but also consider the cost expenditure in the production process, such as labor cost, site cost, electricity cost, adhesive use and other expenses. Most of them are electricity charges, because the equipment is driven by the motor to work. Therefore, customers pay great attention to the parameters such as motor model, power and power consumption.

The high-pressure briquette machine produced by Luoyang Kaizheng is mainly used for making briquettes of nonferrous and ferrous metal ore powder quickly, directly entering the furnace for smelting, and increasing the added value. All waste materials or auxiliary materials in the metallurgical industry need to be put on the furnace, which needs to be completed by a briquetting machine. For example dust removal ash, pool mud, oxide scale, steel slag, iron concentrate powder, aluminum ash powder, silicon manganese ore powder, and so on. Various powders (such as magnesia, bauxite, dolomite, iron powder, etc.) can be made into spherical billets with high density by forced pressurization and preloading spiral precision processing, which are widely used in metallurgy, chemical industry, coal, and refractory industries.

The quality of the briquetting machine determines the ball rate and strength of the briquettes pressed out by the machine, which is the focus of the vast number of users. There are three standards to judge the overall performance of the briquette machine, which are: briquetting pressure, briquette strength, and briquette hardness.
