The process of removing unwanted elements from those which are wanted is called sieving. Apart from this the process is also used to separate particles of various shapes and sizes in order to refine the product. In most of the cases a siever has a net to screen out the unwanted material.

Typically a sieving machine consists of two chambers – one which collects the required material, and the other wherein unwanted material is collected. Depending on the industry of work, seiving machines come in various shapes & sizes. Broadly they are of three types:

  1. Perforated plate sieves: It confirms to the ISO 3310-2 and has a diameter range from 200 to 450 millimeters. The appertures in the perforated plate sieves ranges from 1 millimeter to 125 millimeters and are square/ round in shape.

  2. American standard sieves (ASTM): They conform to the ASTM E11 standard and unlike the perforated plate sieves, are available in only 8 and 12 inch diameter sizes. Their nominal aperture ranges from 20 micrometers to 200 millimeters.

  3. Woven wire mesh sieves: This is the most commonly used sieves. They confirm with the ISO 3310-1 and have a nominal aperture ranges from 20 micrometers to 3.55 millimeters. Their diameter ranges from 100 to 450 millimeters.


Based on the end-requirement, sieves are selected and brought into use. According to Logos Weld – leading sieve machinemanufacturers in India – it is important that the size and capacity of the work load should be taken into consideration before investing on any such machines. The other important aspects that needs to be paid attention to are:

  • The construction of the sieve
  • Its design
  • The housing should be non-corrosive in nature
  • Most of all, the sieve should be easy to maintain


Logos Weld also recommend a sieve analysis test before settling on a sieving machine. A sieve analysis is basically a process through which the gradation or the size of the particles to be separated can be assessed. This test can be performed on organic as well as non-organic materials. Usually this process is quite widely used in the area of civil engineering. But those belonging to other industries too can make use of this analysis so that they choose an appropriate siever.
