Size reduction refers to the process of reducing the size of drugs into smaller particles or fine powder. It involves cutting or breaking particles of solids into smaller pieces. Size reduction becomes necessary when the starting material is too coarse and the desired final product needs to be in the form of a fine powder. … Read more
Size Separation involves the separation of a mixture containing particles of various sizes into two or more portions. This can be done through the use of screening surfaces or by shifting the mixture. It is also commonly known as sieving, sifting, or screening. The technique of size separation is based on different physical properties of … Read more
Air Separator is a pneumatic device that sperate the materials based on their size with the help of air current. This sperate the materials of lighter density from those of greater density and smaller size particles from the bigger ones. Air Separator Principle: The air separator operates based on a similar principle as the cyclone … Read more
The sieving technique is used widely to separate fine powder from coarse powder by utilizing sieves of specific sizes. By passing the powdered material through a sieve, we can determine the level of separation. Sieves are numbered for easy distinction between them. Working & Construction Size separation of powder occurs as the powdered material passes … Read more
