A test sieve is a screening medium, which has openings of uniform shape and size, and is mounted on a rigid frame. A test sieve is a tool that uses metal cloth with holes in it to separate particles from materials.
A test sieve consists of a screen (often wire mesh) held or surrounded by a round frame and they come in many different shapes, sizes & specifications.
There are many applications and uses of test sieves. Mainly a test sieve is used to separate granules from powdery substances. Test sieves are used in different industries such as food industries, chemical industries, pharmaceutical industries, laboratory industries, building industries, abrasive industries & metallurgy industries.
Classification of Standard Test Sieve:
There are many types of different test sieves that are used for different purposes. Those are Flour sieves for sifting impurities that are there in the flour powder; Grain sieves that are used to separate impurities that are present in different types of grains such as rice, wheat, etc.
A sugar sifter this used to remove or separate the impurities that are present in sugar particles; a Sand sieve is used to separate small pebbles & particles that are present in the sand powder; Stone sieve this sieve separates any form of a powder that is present in the stone chips that are used as a building material. Then there are soil sieves, asphalt sieves, concrete sieves, dry cement sieves & pharmaceutical sieves.
The different sieves come with different types of sieve frames. Shape- there are three main shapes of the sieve frames mainly round, square & rectangle (slot). Thickness- the thickness of the frames should be between 0.6mm to 0.7mm. Height- the height of the screen frames can be 25mm, 50mm or they can be made as per the specification of the customer.
Test Sieve Specification:
The test sieves have certain specifications that must be kept in mind at the time of manufacturing them. First- Colour: the color should be Silver or Brass. Second- Material: the material should be stainless steel. Third- Brass Frame Aperture Size: the aperture size of the brass frame should be 1mm to 4mm.
Fourth- Stainless Steel Frame Aperture Size: the aperture size of the stainless-steel frame should be 1mm to 1.5mm. Fifth- Outer Diameter: the outer diameter of the frame should be 8 inches. Sixth- Full Height Sieves: the full height of the sieves should be 2 inches. Seventh- Available Diameter Sizes: the sieves are available in different diameter sizes; the diameter sizes range from 75mm-600mm.
Test Sieve Features:
There are many features of the test sieve tool, or it can be said that the test sieve has got a lot of salient features. They are High-quality metal potting sieves; the test sieves are Ideal for classifying soil and compost. These machines can be used in Laboratories and Industries for particle size analysis. The sieves have High efficiency and high precision.
To, conclude it can be said that test sieves are a very useful tool that has multiple uses in different industries.
