Instructions
1. Place the sieves together with the largest size at the top and consecutively
smaller mesh as the sieves go under each other.
2. Place the pan under all the sieves.
3. The material to be tested should be thoroughly dried. Material is easiest dried by
spreading out material on newspaper in full sun for an hour or so, lightly stirring
material after 30 minutes until dry.
4. Measure out a dry amount of material on a scale. (An inexpensive postage scale
will work fine.) Use a nice even number in ounces or grams.
5. After the material has been weighed and recorded, pour the material to be tested
into the top sieve.
6. Place the cover on the sieve set and slightly lift top sieve off stack and shake it
over the remaining stack. Be sure all the material from the top sieve falls into the
stack below. Shake the top sieve for a couple minutes. (Shaking time may vary
from mix to mix depending on amount of fines.)
7. Remove the cover. Remove the top sieve and pour the material on a clean sheet of
paper and weigh the amount. (A dry toothbrush may be needed to get all particles
out of the sieve.) Record the results.
8. Repeat the weighing process until all the sieves have been emptied and the
results recorded.
9. Finally take each weight and use the following calculation to find the percentage
of each particle size:
Divided Into Multiply By
Weight of Total dry Percent
Particles in Weight of 100 Of
Each sieve Sample Particle
** If scale is unavailable put sand in piles on a piece of cardboard and compare sizes of
piles. A rough estimate can be made of the volume of each separation.
