Sieving Machine for Copper Electrolytic Powder

Sieving machine for copper electrolytic powder is a device used to screen copper powder obtained by electrolysis, which can accurately screen 0-400 mesh copper electrolytic powder. Electrolytic copper powder has the characteristics of fine particle size, large specific gravity, easy agglomeration and easy oxidation. During screening, the sealing, anti-blocking and precision of the equipment are required to be high.

 

According to the application requirements of copper powder, high-precision grading screening of 100 mesh, 200 mesh, 300 mesh and even 500 mesh is often required to ensure the consistency and purity of product particle size. In order to achieve effective grading of copper powders of different particle sizes, the sieving machine is usually designed as a 1-3-layer screen structure, which can complete the multi-stage separation of coarse powder, finished powder and fine powder at one time.

What is the role of the sieving machine for copper electrolytic powder

Copper electrolytic powder is a copper powder produced by electrolysis. Its preparation process usually includes smelting, electrolysis, washing, surface treatment, drying and screening. Electrolytic copper powder has the characteristics of low lead content, low bulk density and developed dendritic structure, which makes it excellent in conductivity and is particularly suitable for the electric carbon industry. In the production process of electrolytic copper powder, screening is an important step for controlling the particle size distribution of copper powder.

The sieving machine ensures that the particle size of the electrolytic copper powder meets specific requirements, because different applications have different requirements for the particle size of copper powder. For example, fine copper powder may be more Suitable for some conductive slurries, while coarser copper powder may be used in some powder metallurgy processes. Through screening, particles that are too large or too small can be removed, thereby obtaining high-quality electrolytic copper powder with uniform particle size distribution.

What are the types of copper electrolytic powder sieving machines?

Sieving machines for copper electrolytic powder usually use vibration screening technology to separate materials of different particle sizes through different apertures of the screen. This sieving machine can efficiently divide copper powder into multiple levels according to particle size, which is convenient for subsequent processing or direct application.

What can the sieving machine for copper electrolytic powder be used for?

Sieving machines for copper electrolytic powder are widely used in many fields, especially in battery manufacturing, electronic components and electroplating industries. In battery manufacturing, sieving machines are used to grade copper electrolytic powder to ensure uniform particles, thereby improving the conductivity and performance of the battery. In the production of electronic components, sieving machines help separate copper powders of different particle sizes to meet the requirements of different components and ensure product quality and stability.

In addition, in the electroplating industry, the screening of copper electrolytic powder helps remove impurities and improve the purity of the electroplating solution, so that the electroplating layer is smoother and more uniform. Through these applications, the sieving machine for copper electrolytic powder not only improves production efficiency, but also optimizes product quality.

How to choose a sieving machine for copper electrolytic powder

For electrolytic copper powder, a metal powder with high requirements for purity and particle size, screening equipment with good airtightness, high screening efficiency and the ability to handle fine powder, such as ultrasonic vibrating screen or swing screen, is usually selected.

The sieving machine for copper electrolytic powder is a fine screening equipment with high requirements for screening accuracy and equipment cleanliness. The specific selection needs to be determined according to the particle size distribution, output requirements and process requirements of the copper powder. The most widely used model at present is the stainless steel ultrasonic vibrating screen, which is suitable for grading electrolytic copper powder with mesh size of 200~500. For powders with extremely high mesh size or serious viscosity problems, airflow screens can also be considered as a supplement.

In actual selection, it is recommended that you combine the specific particle size, characteristics, required processing volume, quality requirements of the final product and budget of the copper electrolytic powder, and consult a professional screening equipment supplier for small batch testing to select the sieving machine that best suits your production line.
