Types of sieve shaker

As a common screening and screening equipment in the laboratory, the test sieve is often asked by users. What kinds of sieves are used? What is the main difference? Today, Xiaobian introduces several common classifications about laboratory screening equipment, which is convenient for users to use as a reference when selecting experimental sieves.

Several common test sieve equipment

1. Standard test sieve

The standard test sieve is also called standard sieve, test sieve, and the test sieve is mainly made of SUS304 stainless steel. The overall shape is strong and durable. The screen and the screen frame are fixed by soldering, which will not be slack and can withstand high temperatures below 300 degrees.

Screening advantages:

1)Can be up to 0.02 mm (20 micron) triangular hole mesh size can be up to 0.005 mm (5 micron), accurate screening.

2)Standard test sieve can be used together with slap screen, top screen, standard screen machine, etc. Up to 8 layers of standard vibrating screen can be installed. The equipment is equipped with a timer and can be shut down regularly to ensure the consistency of each production or test.

2.Pharmacopoeia sieve

Pharmacopoeia screening refers to a test sieve for the production of pharmaceuticals according to the provisions of the Chinese Pharmacopoeia. The sieve frame is made of high-quality stainless steel and is made of high-strength stainless steel. The wall thickness is 0.6-0.7 mm and can withstand temperatures below 300 °C.

Screening advantages:

1)The feeding granularity is between 10-200 mesh, the mesh is accurate, and the sieve machine is tightly sealed, which can ensure that the material does not appear to overflow during the screening process.

2)Pharmacopoeia sieve and test sieve are used together to be more efficient.

3. Test sieve machine

The experimental sieve machine is a new type of experimental sieve designed and inspected by the designated institution and designed under the requirements of the labeling. The whole machine is made of SUS304 stainless steel and is not easy to be deformed, wear-resistant and high temperature resistant.

Screening advantages:

1)The test sieve machine can screen 0.025-3mm material with high screening precision, which can meet the requirements of users who have requirements for precision.

2)Can be automatically shut down at regular intervals to ensure test repeatability and screening more efficient.

4.Soil sieve

A test sieve for soil screening of soil,

Screening advantages:

1)Feeding particle size ≤ 60mm, accurate screening

2)Can be used together with the test sieve machine, and the screening efficiency is high.

5.Ro-tap sieve shaker

Ro-tap sieve shaker is one of the common laboratory equipment in the laboratory. The difference between the two and other test screens is that they use the principle of eccentricity to cause regular vibration and top/slap on the platform surface of the machine. The main supporting standard sample screen is used instead of manual screen, the structure is simple and the screening is accurate.

Screening advantages: 

1)Screening is efficient, and there are two kinds of vibration modes: reciprocating, topping/slapping. In the material screening process, there is no blocking phenomenon and the screening is more thorough.

2)With timing function, the power controller can reserve time and can automatically stop and check production consistency.

The above is the introduction of the type of test sieve. If you need to know more about the difference between these equipments, or consult the price, model and other information, you can contact the Xinxiang Dahan factory at any time, we are always waiting for you.
