Perforated test sieve has two shapes of openings: square and round. Grid sieve is made of frame and bar, and it is used for flakiness testing of aggregates.
Feature
- The frame of testing sieve is made of SUS 304# stainless steel, the thickness is 0.6 mm, firm and durable, no magnetism.
Sieve and frame are soldered all around, then make a mosaic base, as the frame is two-double, so that the testing sieve is more firm and durable.
The testing sieve is processed by use special electrochemistry methods, and coat chrome, so the surface of testing sieve is exact, glazed and wearable,it will not get distorted after long time use
Specification
- Frame material: stainless steel, brass.
- Mesh material: stainless steel wire.
- Standard: ASTM E323-11, ASTM E11-16, E161-12, ISO 565-1990, ISO 3310-1, ISO 3310-2, ISO 3310-3, ISO 2591-1, GB/T 6003.
- Type: woven mesh test sieve, perforated test sieve, grid sieve.
Application
Each kind of special test sieve has its own role, such as: - Microplate sieve is used to help very small particles through the aperture.
- Air jet sieve is widely used in the jet system.
- Wet washing sieve is used to wet all sorts of materials, which allows the fines to be washed without losing.
- Flakiness sieve is mainly used to determine whether the aggregated particles are flaky.

Laboratory test sieve, just as its name implies, it is widely used in the laboratory, except for that, it also can be used in the quality inspection department. Laboratory test sieve has high precision, so it becomes a precision measuring instruments for particle size analysis.
Feature
- High precision, accurate mesh.
- High temperature resistance, anti acid and alkali.
- Suitable for all kinds of powders and particles.
- Easy to clean and maintain.
Application
Laboratory test sieves are widely used as precision measuring instrument in particle size analysis in laboratory and quality inspection department.Sieve shaker is a high efficiency instrument for sieving. It feature of high frequency makes it become an ideal choice for fine particle
separation. The sieve shaker combines transverse and up-down and tilt motion to make the test material shake in the sieving orbital. This fast and effective movement utilizes the mesh area and ensures the sieving and separation of the test materials. In addition, see-through cylinder is helpful for observing.
Feature
- Low noise.
- Sieving can be done in a dry and humid environment.
- Even in a short time, there is an excellent sieving efficiency.
- The sample can be moved evenly on the sieving surface.
- Easy operation, free maintenance.

Application
Sieve shaker can be used to sieve grain, fiber, flat crystals, plants and so on in research and quality inspection department.
