round sieve is a kind of laboratory sieving equipment. There are two options of manual sieving and machine sieving. Machine sieving can use a sieving machine instead of manual sieving. The sieving machine has an automatic timing function of 0-99 minutes, which can Ensure the accuracy and reliability of analysis between sample groups, saving time and manpower.
1. Dry sieving: It is used to process dry or free-falling high-flowing particles and powder samples. These samples can flow and separate by themselves, and are suitable for processing powder particles such as chemicals, food, and medicine.
2. Wet sieving: use liquid substances to process samples that are difficult to pass through the screen or are solid. The method is to apply liquid (usually water) to the test sample to make the fine particles pass through the sieve, while grading and agglomerating, and then Samples are dried and evaluated, and wet sieving is suitable for samples with a high concentration of fine particles or samples where the particles are not easily broken by mechanical shaking. Clays, such as clay or silt, for example, can clump together to form larger particles that cannot pass through the mesh.
