Size reduction has become an essential part of many different manufacturing processes. From pharmaceutical production to agricultural and even cosmetic applications, size reduction is an integral part of the production of almost every product out there. What is Size Reduction? Size reduction is, essentially, the breaking down of materials from a few large particles, usually
Many particle size measurements are made to track size reduction operations such as milling, mixing, homogenizing, etc. The size reduction unit operation is performed under set conditions or for a required time frame until a specified size is achieved. The choice of particle size analysis technique can be based on the size distribution of the input, output, or both.
employed in size reduction of pharmaceutical poders includes units from 50mm to 500mm, but most are in the 100mm and 200mm size range.Table 1 shows some typical mill sizes with their relative fineness and throught ranges. Jalay T. Joshi / Journal of Pharmaceutical Science and Technology Vol. 3 (7), 2011,651-681 652
The right size reduction machine for the task is the one that can add energy most efficiently for the application. From the beginning of time, humans have found it necessary to make little pieces out of big ones stone, ore, ice, grain and more. It was a slow, laborious process for many centuries. Then in the Stone Age came the first ...
