What is a fiber inflation sieve tester?
2023-07-06
The fiber-inflated sieve analyzer is an instrument used to analyze the particle size distribution of graded powders and fine-particle samples.
It works by using an airflow to classify the sample and then determining the distribution among different particle sizes through either quantitative or gravimetric analysis.
The main steps for using the fiber inflation sieve tester are:
1. Prepare the sample: The sample must be dry and free of obvious agglomerates. If the sample contains micelles, it needs to be first subjected to crushing or ultrasonic treatment before being spread onto a flat surface.
2. Select the sieve mesh: Choose a suitable combination of sieve meshes based on the expected particle size range of the sample.
3. Loading the sample: Evenly load the predetermined amount of sample onto the top of the sieve mesh.
4. Set test conditions: Adjust the air pressure and duration according to different samples.
5. Start the test: Turn on the air compressor to begin sieving; the air will separate the sample into different sieve sizes.
6. Graded sample collection: After the test is completed, collect the graded powder from each sieve and weigh the mass of each particle size fraction.
7. Calculation results: The particle size distribution curve is calculated based on the weight proportions of different particle size fractions.
8. Clean the sieves: Thoroughly clean all sieves after testing.
The above is the main procedure for using the fiber inflation sieve tester. During the process, it’s important to note that the sample should be kept dry, the sieve mesh should be selected appropriately, and the air pressure and duration should be adjusted according to the specific sample.
