Pre-magnesium treated silicon monoxide anode material powder production by jet mill

Airflow Crusher for Pre-Magnesium Coated Silicon Monoxide Anode Material in Lithium Batteries

In the project of coating pre-magnesium silicon monoxide anode material, the airflow crusher is used to crush and mix the silicon monoxide material to achieve the required particle size and uniformity. This treatment is crucial for improving the electrochemical performance of the material, as the particle size and morphology directly affect its application performance in batteries. The use of the airflow crusher not only enhances production efficiency but also ensures the quality and consistency of the material, thereby providing a guarantee for battery performance and safety. Additionally, by replacing the ordinary air in the gas source part with inert gases such as nitrogen or carbon dioxide, the airflow crusher can be transformed into an inert gas protection device, suitable for the crushing and classification processing of flammable, explosive, and easily oxidized materials, ensuring the stability of the production process.

Applicable Model: ZJ-DBQ

The inert gas protection crushing and classification machine uses fluid dynamics numerical simulation software to calculate the appropriate flow field and ideal pressure distribution to guide the design, optimizing the structure of the classification impeller. The flow field is uniform and stable, with minimal pressure loss in the impeller, enabling effective material classification.

◆ Wide range of applications, allowing the selection of suitable inert gases as protective gases based on the characteristics of flammable, explosive, or easily oxidized powders.

◆ The purity of the inert gas can be controlled according to process requirements and product characteristics.

◆ Utilizes a closed-loop system where inert gas is recycled, resulting in minimal loss.

◆ Classification blades are formed in one piece and balanced to ensure smoother operation of the equipment.

◆ The entire system is controlled automatically by PLC, enabling automatic replenishment and discharge of inert gas to maintain system pressure balance, truly achieving a one-click start-stop operating system.

◆ Increased filter area of the dust collector, combined with a pulse cleaning system, ensures long-term stable operation of the system; filter materials are selected for high efficiency, with a collection efficiency of ≥99.99%.

◆ Equipped with an airflow regulating valve and a stepless speed regulator for the classification impeller, allowing adjustment of product particle size without shutdown.

◆ Unique flow field design and constant gas-solid concentration control ensure short residence time of materials in the chamber.

◆ High product quality, with fewer large particles observed in electron microscopy scans, providing strong classification effects for ultra-fine powders.

◆ The recycling of inert gas ensures that during the production process, the system's oxygen content is controlled within 100-5000 PPM (this value depends on material characteristics, on-site inert gas purity, inert gas flow rate, and pressure).

◆ All flange connections use standard flanges, ensuring tight connections, high strength, and excellent sealing.

◆ Due to material characteristics, some materials may adhere to the equipment after crushing. For such materials, manhole doors can be installed at prone adhesion points, allowing for easy manual cleaning after shutdown.
