Standard Test Sieve is mainly used to filter and detect the particle size structure of granular and powdery materials, the content of liquid solids and the amount of debris. It is mainly used in various laboratories, laboratories, item screening, sieving, grading, etc. In the inspection department, in order to ensure the standardization and accuracy of the data for testing raw materials, Standard Test Sieve is often used with DH-300T test sieve machine. The following is the basic operation steps of Standard Test Sieve produced by Dahan Vibration Machinery for the convenience of users:

1. The test sieve machine should be placed horizontally, confirm that the power supply meets the requirements of the nameplate, and ensure that it is grounded; the vibrating part cannot be in contact with other objects; whether the bolts of each part are locked.

2. Determine the Standard Test Sieve box to be selected according to the inspected material and the corresponding standard.

3. Stack the Standard Test Sieve frame on the vibrating plate of the test sieve machine in sequence from small to large apertures and from bottom to top.

4. Put the material to be inspected into the Standard Test Sieve frame at the upper end, cover the Standard Test Sieve upper cover, adjust the height of the adjusting rod according to the total height of the Standard Test Sieve frame, and then use the pressure plate and the lock nut to adjust the Standard Test Sieve frame Positioning and pressing (Note: The force on both sides should be the same).

5. According to the nature of the material and the amount of feeding, set the running time on the timer, then turn on the power switch, and the Standard Test Sieve will start working.

6. After the Standard Test Sieve stops working, unscrew the lock nut, remove the pressure plate, and carefully remove the Standard Test Sieve frame.

Seven, cut off the power.

The commonly used specification for Standard Test Sieve is 200mm in diameter. Standard Test Sieve screen materials are divided into three types. Wire braided screen surface is widely used, and the mesh size ranges from 2.36mm to 0.02mm; the main application of perforated plate screen is For large meshes, there are two types of round holes and square holes; electroforming screens are mainly used in high-precision occasions, and each mesh can be within the average error range.
