Pneumatic conveying scheme for cobalt oxide

During the processing and transportation of cobalt oxide powder, enterprises often face challenges such as material settlement blockages, unstable conveying speeds, and dust dispersion. Traditional mechanical conveying methods tend to wear equipment easily, frequently leak material, and consume high energy; Manual handling is inefficient and labor-intensive. How to achieve continuous, sealed, and low-energy automated conveying has become a core issue that the related industry urgently needs to address.

Material characteristics

Cobalt oxide is a black or gray-black powder with a density of about 5.68 g/cm³, and a particle size usually between 0.5~50 microns. It is characterized by easy agglomeration, poor flowability, and sensitivity to moisture. Additionally, cobalt oxide is a fine dust matter that poses common health risks when suspended in the air, so the conveying process requires high sealing and dust protection.

Product Introduction

Head Powder has launched a cobalt oxide pneumatic conveying system, using sealed pipelines under positive or negative pressure, using compressed air or inert gas as carriers to smoothly transport cobalt oxide powder from the feed end to the workstation. The system includes a feeding device, sending tank (or rotary valve), conveying pipeline, dust collection, and control modules, and can be customized according to customer site layout, conveying distance, and conveying volume. This system is suitable for the transfer of cobalt oxide powder in industries such as lithium battery cathode materials, ceramic glazes, catalysts, and electronic materials.

Product advantages

To address customer pain points, Head Powder offers the following optimization solutions:

• Anti-clogging design: Uses fluidized cone and a special nozzle structure to effectively prevent cobalt oxide from bridging and caking inside the sending tank, helping to ensure continuity of conveying.
• High sealing: Fully enclosed pipeline transportation, combined with high-efficiency filtration devices, basically eliminates dust leakage, reduces material loss, and improves the working environment.
• Intelligent control: Integrated PLC and touch screen, allowing preset conveying parameters, automatically adjusting gas-solid ratio and gas flow rate, reducing human operation deviations, and improving operational stability.
• Low energy consumption operation: Optimize airflow speed according to material characteristics to avoid excessive energy consumption; At the same time, system energy consumption is reduced by about 30%~50% compared to traditional mechanical conveying (depending on specific working conditions).

System features

• Customized matching: Based on cobalt oxide particle size distribution, humidity, and fluidity data, design suitable pipeline inner diameter, elbow radius, and sending tank volume to achieve material transport without backblowing or sedimentation.
• Lightly worn structure: The inner wall of the pipeline uses wear-resistant coatings or thick-walled seamless steel pipes, with wear-resistant plates added at elbows to extend equipment service life and reduce maintenance frequency.
• Optional nitrogen protection: For gas environments requiring anti-oxidation or explosion protection, the system can be equipped with nitrogen displacement and pressure holding functions to support process safety.
• Modular installation: Each unit uses quick-install interfaces, making on-site assembly, expansion, or relocation convenient, shortening project cycles.
