Pinciple

Vibratory sieve shakers use YZU vertical vibration motor as the vibration source of the whole machine, drive the upper vibrating plate to vibrate through the vibration motor, and then transmit it to the upper screen frame of the vibrating plate through the vibration plate, and then the screen frame needs to detect the mesh number. The material particles smaller than the sieve aperture are sieved to the lower sieve frame, so that only the same particle size remains in each layer of the test sieve, so as to achieve the separation of different particle sizes and determine the particle size composition of the material.

Different Sieving Methods

Once these questions are answered satisfactorily, the appropriate sieving method can be selected. Vibrating screen, wet screen vibrating screen or jet screen.

1.Vibratory sieving: Vibratory sieving allows the sample to move in three dimensions. The vertical throwing motion is superimposed with the circular motion. This mechanism distributes the particles evenly over the entire sieving surface and is thrown into the air, where they ideally change their orientation, allowing them to be compared to sieve openings of all possible sizes.

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.

3.Jet Screening: To obtain a screen cut through an air jet screen, only one screen is used instead of a bunch of screens, and the screen itself does not move. Industrial vacuum cleaners create low pressure in the screen chamber. Intake air escapes at high speed from rotating slit nozzles below the screen and disperses particles, which can then be compared to the screen openings. When the particles hit the screen cover, they are not only redirected but also deagglomerated. Small enough particles are then transported through the screen and sucked out. They can also be collected in cyclones.

4.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.

Scope of application

It is used in laboratories and quality inspection rooms to accurately analyze the particle size structure of particles and powder materials and test and analyze the liquid solid content. The screening accuracy is accurate and the efficiency is high.
