Bangpu, founded in 2005. It is located in the National Energy Saving and Environmental Protection New Material Industry Base in Changsha, Hunan, with a total registered capital of RMB 60 million and RMB 18 million, respectively. It is a key high-tech enterprise of the national torch plan, which specializes in the recycling and disposal of used batteries and scrap cars, and the production of high-end battery materials.

I. Material description

Ternary precursors are the main raw materials for manufacturing ternary materials. The production of ternary materials requires the same amount of ternary precursors. Ternary precursors currently account for about 55% of the cost of ternary materials. According to industry insiders, precursors are critical to the production of ternary materials, because the quality of the precursors (morphology, particle size, particle size distribution, specific surface area, impurity content, tap density, etc.) directly determines Physical and chemical index of sintered product. It can be said that the technical content of ternary materials is 60% in the precursor process. Because of this, as a part of the ternary precursor production process, the quality of the drying is also considered to be the result of the entire product.

 
Equipment description
This system mainly includes air filter, drying machine, discharge valve, exhaust dust collector and control system. The single line of the product line has a daily output of 16 tons and works for 16 hours a day. The single line is completed with 2 dryers, with a total of 4 production lines. 4% 之间。 After the wet cake with a moisture content of 10% is dried, the moisture content of the final product is controlled to 0.4% or less.

This equipment adopts mature foreign technology and combines domestic production standards to make its production system reach the highest cost performance. The main body of the material is polished with 304 stainless steel mirror. In order to reduce heat loss, the upper cover is made of aluminum silicate insulation. There are 3-4 personal holes above the upper box, which is convenient for entering the inside of the dryer for maintenance and cleaning through the manhole. The structure style of the paddle blade is specially designed, and no sharp edges and burrs are used in the overlay welding process. Pickling and passivation treatment is performed after the welding process.

 
Equipment Features
Low energy consumption of the paddle dryer: Due to indirect heating, there is not a large amount of air to carry away the heat, and the outer wall of the dryer is provided with a thermal insulation layer. For slurry materials, only 1.2 kg of water vapor is required to evaporate 1 kg of water.

Low cost of the paddle dryer system: With a huge heat transfer surface per unit effective volume, the processing time is shortened and the equipment size is reduced. It has greatly reduced the building area and building space.

Wide range of materials to be processed: Different heat media can be used to handle both heat-sensitive materials and materials that require high temperature processing. Commonly used media are: water vapor, thermal oil, hot water, cooling water, etc. It can be operated continuously or intermittently, and can be applied in many fields.

Low environmental pollution: Do not use carrying air, and there is little entrainment of dust materials. The solvent evaporation of the material is very small, which is easy to handle. For contaminated materials or working conditions where solvents need to be recovered, a closed circuit can be used.

Low operating costs: structure. Minimal wear and low maintenance costs.

Stable operation: due to the special compression-expansion stirring effect of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial interval, the temperature, humidity and mixing gradient of the material are small, thereby ensuring the process. stability.
