Through practice, it is found that the finished ore produced by grate rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more fuel available and strong adaptability to raw materials. This paper introduces what equipment should be equipped with the production line equipment.

Mixing of highly viscous fluids is a common unit operation in industry, and many industrial sectors encounter mixing or kneading operations of highly viscous fluids, such as rubber, petroleum, plastics, coatings, inks, and synthetic fibers, cosmetics, pharmaceuticals, food, paper and cement industries.

Manganese powder ore generally refers to fine-grained concentrates obtained by beneficiation, and fine-grained materials containing manganese such as soot and ash obtained from smelting manganese ferroalloys in blast furnaces and electric furnaces. The briquette method is one of the manganese powder ore agglomeration methods.

The Pellet method represents the development direction of fine powdery iron concentrate, bentonite as a dry binder plays a decisive role in the process of caking, therefore, it is of great significance to study the bonding mechanism of bentonite to iron ore pellets.

As the main raw material for direct reduction of rotary hearth furnace, the cold consolidated carbon briqued coal needs to go through transportation, distribution, reduction, discharge and other processes in the production process of rotary hearth furnace, so its performance in all aspects affects the smooth production and efficiency of rotary hearth furnace. In this paper, syrup was used as binder, vanadium titanium magnetite and pulverized coal were used as raw materials to study the influence of different binder ratio, forming pressure and water content on the cold consolidation performance of carbon pellet.

There is a shortage of scrap in steelmaking around the world. Due to the small domestic self-sufficiency of scrap in China and the unstable quality of scrap available, it is necessary to find alternatives to scrap.

Rotary hearth furnace technology (RHF) was developed and built in the United States in 1978 by the International Metal Company affiliated to INCO Group of Canada in order to treat and utilize metallurgical wastes. It can not only be used to treat dust produced by metallurgical plants and other wastes containing iron, chromium， and zinc, but also be used to reduce iron ore.

Ore powder briquette machine can be used to press pulverized coal, iron powder, coking coal, aluminum powder, iron filings, iron scale, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke powder, and other powders, powder materials, waste materials, and waste residues. It is widely used in refractory, power plant, metallurgy, chemical industry, energy, transportation, heating, and other industries. It is energy-saving, environment-friendly, convenient for transportation, improves the utilization rate of waste materials, and has good economic and social benefits.

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.
