It has been found through practice that the finished ore produced by the grate machine rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more usable fuels, and strong adaptability to raw materials. This article introduces what equipment should be equipped with this production line equipment.

Rotary kiln is a commonly used production equipment in modern industrial production. It is widely used in chemical industry, building materials, non-ferrous metallurgy, ferrous metallurgy and other industries, such as: drying and oxidation roasting of materials in the chemical industry; drying of raw materials in the building materials industry and dolomite roasting; oxidative desulfurization of raw materials in the nonferrous industry, synthesis of reagents; drying of ore powder, preparation of smelting flux, production of oxidized pellets, production of direct reduced iron, and smelting of ferronickel in the steel industry.

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.

The tunnel kiln process is relatively simple, the technical content is low, and the raw materials, reducing agents, and fuels are easy to solve. The process has strong practicability, small early investment, and is suitable for small-scale production. It is a metallurgical reduction production process commonly used in the powder metallurgy industry.
