프로젝트 배경
With the rapid development of new energy materials, conductive composites, and functional carbon materials, the demand for coconut shell carbon powder has been rising year by year. This demand is particularly strong in fields such as battery anode materials, conductive coatings, composites, and eco-friendly adsorbents.
However, the production of high-quality coconut shell carbon powder places extremely high demands on particle size uniformity, specific surface area, and dispersion. Traditional mechanical grinding methods often suffer from several issues.
These include uneven particle size distribution, low fine powder yield, high energy consumption, and severe dust pollution.
These methods struggle to meet the high standards demanded by the new materials industry.
To address this challenge, a leading domestic new materials company introduced the Epic Powder 에어젯 밀 for the ultrafine grinding of coconut shell carbon, enabling the production of high-quality carbon powder.
Process and Equipment Selection
The core objective of this 프로젝트 is to produce coconut shell carbon powder with a particle size of D50 ≈ 7 μm. The powder must exhibit high fineness, uniform particle size distribution, and be free of agglomeration. Following a systematic evaluation, the 에픽 파우더 air jet mill was selected as the key grinding equipment for coconut shell carbon. Its features include:
High-Speed Air-Jet Milling
The coconut shell carbon is broken down using the impact and collision forces generated by high-speed jets of compressed gas. This ensures controllable particle size and uniform distribution of the fine powder.
Dry Ultrafine Milling
The air-jet mill employs a fully dry milling process that requires no liquid addition, eliminating the need for washing or drying steps. This simplifies the production process and reduces energy consumption.
정밀한 입자 크기 제어
The built-in air 분류 system allows for precise control of the target particle size (D50 ≈ 7 μm) by adjusting the rotational speed. This improves the yield of qualified finished micro-powder and reduces the need for recirculation.
Low-Contamination Design
The fully enclosed system design effectively suppresses dust dispersion. This ensures a safe production environment and meets modern green production requirements.
