department of a textile mill requires substantial quantities of thermal energy in the form of steam as a source of heating. The various ways and means by which a substantial portion of huge quantities of thermal energy consumed during the course of textile wet processing can be saved include the following. 1.

The sample is heated at 130oC in an air oven for 1 hour. 3.The sample is cooled to room temperature and the residue is weighed. Moisture content is determined by heating a flour or ground wheat sample in an air oven and comparing the weight of the sample before and after heating. The amount of weight loss is the moisture content.

The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material e.g. glass, zircon oxide, steel) and the product to be dispersed. In the milling vessel, the grinding medium is kept moving by the agitator, which itself is driven by a motor.

Wet sieving: the separation of fines from the coarse portion of a sample while suspended in an aqueous solution introduced to a testing sieve. The liquid medium is used to negate static charges, break down agglomerates and lubricate near-size particles. After the fines have been washed through the sieve, the residue is oven-dried and re-weighed.
