TECHNOLOGIES AND EQUIPMENT FOR THE PRODUCTION OF POWDERS

The technological scheme of powder production includes the following operations: grinding, sieving, mixing (in the manufacture of complex powders), dosing (packing) and packaging. The need to perform certain technological operations depends on the prescription, medical purpose and type of starting preparations. If the starting materials (medicinal and auxiliary substances) do not meet the required fractional composition specified in the regulations, they are crushed. Grinding refers to the mechanical process of dividing pieces of solids into smaller ones or turning them into powder, as a result of which the surface of the processed material increases significantly, which significantly accelerates the dissolution of medicinal substances. The goals of grinding are as follows: to provide a rapid therapeutic effect by reducing the particle size and increasing the amount of substance; to obtain a uniform powder mixture; to ensure the accuracy of dosing when dividing the powder mass into separate doses; to obtain a semi-finished product used by the enterprise for the manufacture of solutions, extracts, tablets. The main goal of the grinding stage is to achieve a faster and more complete ...
