During the production of lithium battery anode materials, the conveying stage of silicon carbon powder often faces issues such as dust accumulation, pipeline blockages, and high material loss. Enterprises not only need to support a clean production environment, but also help ensure the stability and continuity of material transportation, avoiding capacity losses caused by equipment failures or inefficiency. In addition, the unique characteristics of silicon carbon powder—such as its lightweight, easy agglomeration, and high hardness—place more detailed requirements on the sealing, wear resistance, and pneumatic parameters of the conveying system.

Material Characteristic Analysis

Silicon carbon powder is a powder material with low density, fine particle size, and high surface activity. It has poor flowability and is prone to bridging, delamination, and electrostatic adsorption during transportation. Its particles have relatively high hardness, posing significant wear risks to the pipe wall and elbows; At the same time, some silicon carbon powder is hygroscopic, and if humidity control in the transport environment is not properly controlled, it can easily clump and block the pipeline. These characteristics make traditional mechanical conveying methods inadequate, while pneumatic conveying solutions require targeted design of air velocity, material-air ratio, and pipe material.

Product Introduction

The silicon carbon pneumatic conveying system provided by Head Powder is based on the principle of positive pressure dilute or dense phase conveying, and is specially developed for fine powders such as silicon carbon powder. This system includes a feeding device, delivery pipelines, gas source equipment, gas-solid separation device, and intelligent control system. The feed end uses a fluidized bed or mechanical seal method, helping materials enter the feed pipe evenly; The inner wall of the pipeline is treated for wear resistance, and the elbow adopts a detachable structure for easy maintenance; The separation end is equipped with a high-efficiency pulse baghouse dust collector, ensuring thorough separation of materials and gases, and exhaust emissions meet environmental standards. The system adopts a closed circulation design to curb dust leakage at the source.

Product advantages

To address dust pollution and blockage challenges during silicon carbon powder transportation, Head Powder equips each solution with real-time air volume adjustment and anti-clogging blowing devices. The system can automatically match the appropriate air velocity based on material characteristics, reducing pellet crushing and pipeline wear. Closed pipelines not only protect operator health but also keep material loss at an extremely low level. At the same time, the modular design allows users to flexibly add conveying points according to production line expansion needs, reducing the cost of later technical upgrades. The control system uses a PLC combined with a touchscreen interface, enabling remote monitoring of conveying pressure, flow, and equipment operating status, enabling one-touch start-stop and fault warning, thereby enhancing the factory's automation management level.
