Effect of Sieve Mesh on Oil Recovery
The effect of sieve mesh on OR is shown in Fig. 3. The mesh number of
the sieve has a significant effect on the OR. Among all the sieve meshes
studied, the OR was the highest under the condition of using a 100- mesh
sieve.
When the solid particles were ground to be too fine, their surface areas
are increased. This may increase their capacity of holding oils so that
OR can be significantly reduced. The grinder capable of performing
seamless (or gapless) grinding such as wheels (or a wheel) or rollers
(or a roller) combined with a sieve may give better results as compared
to other type of grinders.
