What is a ceramic powder test sieve?

Ceramic powder test sieve is a screening device used to accurately measure the particle size distribution of ceramic powder and analyze the particle size distribution of ceramic powder. It separates and grades ceramic powder according to particle size through a series of sieves with precise apertures. It plays a vital role in the production, research and quality control of ceramic materials. It is used to measure the particle size distribution of ceramic powder to ensure that it meets production standards and process requirements.

Working principle of ceramic powder test sieve

The working principle of ceramic powder test sieve mainly relies on a series of sieves with precise apertures to separate and grade ceramic powder according to particle size through vibration or manual methods.

What is the ceramic powder test sieve used for?

1. Quality control of ceramic raw materials: The particle size distribution of ceramic raw materials (such as kaolin, alumina, zirconia, etc.) directly affects the sintering performance and final performance of ceramic products. Using a ceramic powder test sieve can accurately measure the particle size of the raw materials to ensure that they meet production standards.

2. Production process control of ceramic powders: In the preparation process of ceramic powders (such as ball milling, spray drying, etc.), it is necessary to monitor the particle size changes of the powders in real time to optimize the process parameters. The ceramic powder test sieve can quickly provide particle size data to help production personnel adjust the process in time.

3. Research and development and performance testing of ceramic products: In the research and development process of new ceramic materials, it is necessary to analyze the impact of powders of different particle sizes on product performance. In the performance test of ceramic products, it is necessary to measure the particle size distribution of the powder to provide a basis for performance analysis.

4. Particle size classification of ceramic powders: According to different product requirements, ceramic powders are classified according to particle size. The ceramic powder test sieve can be used for particle size control during the classification process to ensure classification accuracy.

What is a ceramic powder test sieve made of?

Ceramic powder test sieve is mainly composed of several core parts, including screen, screen frame, fasteners, sealing ring, bottom cover, top cover, sealing ring, handle and other accessories. These parts work together to achieve accurate screening of materials and ensure the efficiency and accuracy of the test sieve in the process of particle separation and grading.

Application of Ceramic Powder Test Sieve

1. Ceramic product production: In the slip casting process, ceramic powder needs to be screened to ensure the fluidity of the slurry and avoid clogging the mold. During dry pressing, the powder particle size distribution affects the molding density and strength, and screening ensures that the powder meets the requirements.

2. Special ceramics: Electronic ceramics have strict requirements on powder particle size, and screening ensures that the powder meets high-precision requirements. Bioceramics are used in the medical field, and screening ensures that the powder is non-toxic, uniform in particle size, and meets biocompatibility requirements.

3. Ceramic coating: Before spraying the ceramic coating, the powder needs to be screened to ensure uniform particle size, uniform coating uniformity and adhesion. Screen the powder before sintering to ensure consistent particle size and avoid defects during sintering.

Aperture and Mesh Conversion

How do you use a ceramic powder test sieve?

Loading samples: First, place the ceramic powder sample to be screened into the sieve frame.

Vibration: If the equipment is equipped with a vibration device, start the vibration device to vibrate the sieve frame. Vibration can cause the powder particles to move on the sieve and speed up the screening.

Screening: Under the action of vibration, the ceramic powder particles pass through the sieve, and the large particles cannot pass through the sieve and are retained above, while the small particles pass through the sieve and fall into the container below.

Grading: According to the aperture size of the sieve, particles of different sizes will be separated to form ceramic powders of different particle sizes. In this way, the ceramic powder can be graded to obtain products of different particle sizes.

Collecting samples: Collect the ceramic powder particles that pass through the sieve for subsequent analysis, quality control or application in the production process.
