Sieve Test-DAHAN Vibration Machinery

What is the sieve test?

A sieve test is a method used to determine the particle size distribution of a granular material. It involves passing the material through a series of sieves with progressively smaller openings. The sieves are stacked in order of decreasing mesh size, with the finest sieve at the bottom and the coarsest sieve at the top. The material is placed on the top sieve, and mechanical or manual agitation is applied to facilitate the passage of particles through the sieves.

Sieve tests are commonly used in various industries, such as construction, mining, agriculture, and pharmaceuticals, to assess the quality and consistency of granular materials. The results can be used to determine if the material meets specifications, to monitor and control production processes, and to optimize material properties for specific applications.It can quickly and efficiently measure solid particle sizes from 125mm to 20μm. Special sieves with apertures less than 20 μm can be used. The finer the sieve, the easier it is for certain types of solid particles to block or clog the pores. In response to this situation, we have designed an electromagnetic test sieve that can perform "micro" screening. Points up to 5μm.

Types of Sieve Test

Sieve tests are divided into three types, each with different characteristics and application scope:

1. Metal wire braided mesh: widely used, with mesh openings ranging from 2.36 mm to 0.02 mm, only square mesh.

2. Perforated plate mesh: It is mainly used for large meshes, with round holes and square holes, ranging from 0.2 to several hundred millimeters.

3. Electroforming mesh: It is mainly used in high-precision situations, and can ensure that each mesh is within the average error range.

Mesh shape	Diameter	Effective screen surface diameter		H
Mesh shape	Diameter	Min	Max	H
round	75mm	75mm	65mm	25mm
	200mm	200mm	185mm	25mm, 50mm
	300mm	300mm	275mm	75mm
square	300mm	300mm		75mm

How To Perform a Sieve Test?

1. Preparation work: Make sure the standard sieve and screen mesh are clean and intact, and prepare samples of the material to be tested.

Assemble the screen: Select the appropriate screen size and hole diameter, and install the screen on the standard screen. Typically, a standard screen consists of a series of stacked screens with gradually decreasing apertures from top to bottom.

2. Place the sample: Place the sample of the material to be tested on the top screen. Make sure the sample is evenly distributed on the screen and avoid piling up or over-compaction.

3. Screening process: Place the standard sieve on the screening equipment, such as a vibrating screen or screening machine. Start the equipment and allow the sample to be sieved on the screen.

4. Complete screening: After the screening process is completed, close the screening equipment and remove the standard screen. Check the amount of sample residue on each screen and record it.

Benefits of Sieve Test

Standardization

Sieve test is designed and manufactured according to international or industry standards, with uniform specifications and dimensions, thus ensuring the comparability and consistency of test results.

Data is reliable

A variety of different mesh sizes are provided to adapt to the screening needs of materials in different particle size ranges, and can quickly and effectively measure solid particle sizes from 125mm to 20μm.

Multi-layer detection

Samples of different sizes are separated through a stack of sieves of different sizes, which can be used individually or stacked up to 8 layers.

Easy to use

It is simple to operate and does not require complex equipment or technology. Simply place the materials to be screened on top of the screen and gently shake or vibrate the screen to complete the test.

Traceability

The manufacture and use of sieve testts follow specific standards and procedures. This makes test results traceable and can be compared and verified with other laboratories or institutions.

Cost effective

The cost of use is low and no additional maintenance and operating costs are required. In addition, the standard test sieve operates at a faster speed and can complete the test in a shorter time, improving work efficiency.

Working Principle of Sieve Test

Sieve test uses YZU vertical vibration motor as the vibration source of the whole machine. The upper vibration plate is driven by the vibration motor to vibrate, and then transmitted through the vibration plate to the Φ200 screen frame placed on the upper part of the vibration plate. The material particles smaller than the aperture of the screen are sieved to the lower screen frame, so that only materials of the same particle size are left in each test screen to achieve the separation of different particle sizes and determine the particle size composition of the material to make the Φ200 screen frame The materials in can be very effective for filtering, grading and sieving purposes.
