Entering the pre-assembly site of the equipment, we witnessed the entire process of assembling the 500KG single-batch silicon-carbon anode carbon-coated rotary furnace. Inside the workshop, the complete machinery was in place, with core components such as the rotary cylinder, gas pipeline, and temperature control module undergoing orderly pre-assembly and debugging. All systems were aligned and assembled according to the process specifications. Through the assembly site, the hardware configuration of the carbon-coated rotary furnace could be visually understood.
Equipment Application Scenarios
In the field of lithium battery new materials, this rotary furnace is mainly suitable for silicon carbon negative electrode CVD carbon coating modification, and can also be used for high-temperature atmosphere heat treatment of porous carbon and various carbon based powder materials, covering the laboratory trial to small-scale trial production stage.
To leverage the high specific capacity advantage of silicon-based negative electrodes, carbon coating modification is a key process, and thermal equipment directly determines the quality of the modified material. Faced with powders such as silicon carbon negative electrodes that are prone to expansion and sensitive to atmospheric purity, it is difficult for ordinary furnaces to achieve uniform coating. Rotary equipment has emerged to solve the pain points in this industry.
Process characteristics of 500KG/batch wrapped rotary furnace
01 Capacity adaptation | Single batch 500KG, pilot to small batch preparation
A single batch can handle 500KG of materials, seamlessly connecting laboratory pilot tests, supporting the smooth transition of materials from pilot research and development to small-scale trial production, and shortening the iteration cycle of new materials from research and development to industrialization.
02 Uniform heating | Rotating and flipping, the powder is uniformly heated, and the coating suppresses expansion
Adopting a rotating dynamic flipping structure, the powder in the furnace continuously rolls and mixes, and the material is heated sufficiently and uniformly, ensuring the integrity and density of the vapor deposition coating layer, effectively alleviating the problem of volume expansion during the charging and discharging process of silicon-based negative electrodes.
03 Controllable working conditions | Temperature and gas coordinated regulation to ensure CVD coating process
Equipped with a sealed atmosphere protection system, it can achieve precise temperature control inside the furnace, while high-precision adjustment of the protective atmosphere components, isolating external impurities from interference, fully meeting the strict production conditions of CVD carbon coating process for high temperature and high-purity atmosphere.
