Conclusions:
The particle size distribution (granulometry) of test chemical by the sieve analysis method was determined to be in the range of 75 micrometer to 500 micrometer.
Executive summary:

The particle size distribution (granulometry) of test chemical by the sieve analysis method was determined to be in the range of 75 micrometer to 500 micrometer. Majority of the particles were found to be in the size more than 150 (40.32%) micrometer in size.
