Preparation And Solid

The aim of this study was to characterize the effects of high-energy ball milling on saquinavir solid-state characteristics and aqueous solubility for the design of effective buccal drug delivery systems. the solubility of saquinavir mesylate was evaluated in simulated saliva before and after milling for 1, 3, 15, 30, 50, and 60.The maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be.

Milling Formulas And Definitions

Milling Formulas And Definitions

The milling process – definitions cutting speed,v c indicates the surface speed at which the cutting edge machines the workpiece. effective or true cutting speed, v e indicates the surface speed at the effective diameter (dc ap).this value is necessary for determining the true cutting data at the actual depth of cut (a p).this is a particularly important value when using round insert cutters.We have calculate effective energy ball milling,the bond work index w i as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding ore in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when for a given size of grinding product the.
