Metal powder test sieve is a device used for accurately measuring the particle size distribution of metal powder. It separates metal powder into different particle size levels through a series of mesh screens with precise mesh sizes. It is usually used for particle size analysis and screening of metal powder in laboratories or production sites. This type of test sieve is usually made of stainless steel or other corrosion-resistant metals to ensure that the screening process of metal powder does not cause contamination or corrosion.

What is the main function of metal powder test sieve?

1. Particle size analysis: By using a metal powder test sieve, metal powders can be classified according to particle size to understand their particle size distribution.

2. Screening: Metal powder test sieve can screen the original metal powder to remove impurities or oversized particles, in order to obtain metal powder that meets the requirements.

3. Quality control: By using metal powder test sieves, the quality of metal powder can be controlled and monitored to ensure that the quality of metal powder meets standard requirements during the production process.

4. Experimental research: Metal powder test sieves are also commonly used in scientific research laboratories to study the physical properties and particle distribution patterns of metal powders.

How does the metal powder test sieve work?

Place a certain amount of metal powder on top of the test sieve. By using the vibration effect of the metal powder test sieve, the metal powder is passed through the sieve. Different particle sizes of powders are separated into different sieve layers, and by measuring the weight of the powder in each sieve layer, the particle size distribution of the metal powder can be calculated.

Main characteristics of metal powder test sieve

1. High precision screening: Metal powder test sieve adopts standardized sieve mesh with precise mesh size, which can finely classify metal powder and achieve high-precision particle size measurement. It is suitable for particle screening from micrometer to millimeter level.

2. Standardization: Metal powder test sieves typically comply with international standards such as ASTM and ISO to ensure the reliability and comparability of measurement results.

3. Diversity: Metal powder test sieve provides multiple screen sizes and screening methods to meet the measurement needs of different metal powders. Provide screens with different aperture sizes to meet the screening needs of different particle size ranges.

4. Durability: Metal powder test sieves are usually made of durable materials such as stainless steel, which can withstand long-term use, friction and impact of metal powder, and extend their service life.

What are the advantages of metal powder test sieve?

1. Preventing oxidation and contamination of metal powder: Metal powder is prone to contact with air during the screening process, leading to oxidation or contamination by other impurities, which affects the quality of the powder. Metal powder test sieves usually adopt a closed design to reduce the contact between powder and air.

2. Dealing with metal powder adhesion and clogging of the sieve: Metal powder, especially fine powder, is prone to adhere to the sieve due to static electricity, humidity, or irregular particle shape, causing the sieve to clog and affecting screening efficiency and accuracy. Metal powder test sieves are usually made of materials such as stainless steel and undergo special surface treatment to reduce powder adhesion.

3. Screening accuracy and repeatability: The particle size distribution of metal powder is crucial for product quality and requires precise measurement. Metal powder test sieve adopts high-precision mesh to ensure screening accuracy. Metal powder test sieve can accurately control the screening time and vibration parameters, reduce human errors, and improve the repeatability of screening results.

4. The safety of metal powders: Some metal powders have flammable, explosive, or toxic properties, and there are safety hazards during the screening process. For flammable and explosive metal powders, the test sieve adopts explosion-proof design to ensure safe operation. For toxic metal powders, metal powder test sieve is equipped with a ventilation system to reduce the exposure risk for operators.

Metal powder test sieve is a commonly used particle size analysis tool in the laboratory, which can help personnel understand the particle size distribution of metal powder, optimize material formulation and process parameters.

Screening process of metal powder test sieve

Preparation of sieve: Select a suitable sieve based on the particle size range of the metal powder, usually using a combination of multiple layers of sieve (gradually decreasing from top to bottom).

Sample loading: Place the metal powder sample into the topmost sieve.

Start the equipment: Turn on the metal powder test sieve, and the metal powder passes through the sieve under vibration, layering according to particle size.

Collect samples: After screening, collect the powder from each layer of the sieve, weigh it, and record the data.

Analysis results: Based on the screening results, analyze the particle size distribution of the metal powder and evaluate whether it meets the process requirements.
