The atmosphere rotary furnace is a kiln equipment recommended by Xianyang Ceramic Research Institute, also known as the non-ferrous metal powder heat treatment rotary furnace. It is a small ceramic calcination rotary furnace used for sintering and reducing metal powder copper powder. It is also suitable for oxidizing (such as air) or reducing atmospheres (such as nitrogen hydrogen mixture) such as lithium iron phosphate, lithium battery negative electrode materials, metal powders, etc The sintering reaction below is also applicable to the oxidation treatment of catalyst carriers in the chemical industry, as well as high-tech materials such as graphene, nanomaterials, rare earth, etc. It can also be used for semi industrial production, limestone calcination, metallurgy, geology, mining, chemical, building materials, and other departments to conduct calcination tests on samples
The materials are rotated and heated inside the drum, and the furnace body is generally made of lightweight refractory insulation bricks or ceramic fibers. The drum selects different materials of steel based on temperature and material properties. The rotary furnace includes a tubular preheating furnace, a reducer, a bracket, a segmented partition board, and a tubular sintering furnace. The outer layers of the preheating furnace tube and the sintering furnace tube are respectively equipped with heaters, and thermocouples are installed inside the tubes, which are connected to an automatic temperature control instrument; The reducer drives the preheating furnace and sintering furnace to rotate through a linkage chain. During the rotation process, the wing plate cuts the bonding material in real time, effectively preventing the formation of rings The atmosphere rotary furnace uses a rotating dynamic calcination mode and a static sagger loading calcination method, which can overcome the defects such as raw, overburned, and entrained during the powder material calcination process, thereby improving the reaction time and quality uniformity of the powder material. In terms of the material of the furnace body, it has high thermal efficiency and low energy consumption, and its energy-saving efficiency is 50% higher than that of conventional kilns. A flexible and reliable automatic control system has been adopted, greatly improving the automation level of equipment operation. Temperature curves can be set according to time and temperature gradients in different parts and sections for fully automatic firing. The rotary dynamic calcination technology relies on professional thermal technology design capabilities to ensure the reliability and technological maturity of this type of equipment. It has been widely used in fields such as electronic battery materials, rare earth deep processing materials, chemical materials, light industry, and mineral materials
