RUSSIAN UREA

SPECIFICATIONS FOR PRILLED/GRANULAR UREA (BULK) FERTILISER GRADE

DESCRIPTION: The material shall be in the form of white free flowing granules, prills or pellets or shots, shall be free from visible impurities and dust. The material must be chemically treated and coated to reduce Hygroscopicity.

NOTE: The material shall be considered free flowing at the time of unloading, if the prills/granules are separate from each other, the lumps or crust formed in the hatches of vessels are broken with slight pressure of fingers into separate prills/granules and if the cliffs formed near the walls of the hatches can be broken by slight pressure with bamboo sticks/or iron rods.

The material shall also comply with the requirements specified in the table below:-

S.NO. CHARACTERISTICS REQUIREMENTS
1 Moisture percent by weight maximum 0.5%
2 Total Nitrogen percent by weight (on dry basis) minimum 46%
3 Biuret percent by weight, maximum 1.5%
PARTICLE SIZE (PRILLED)

The portion of the material passing through 2.8 mm IS SIEVE (Tyler Sieve 7) and retained on 1 mm IS SIEVE (Tyler Sieve 16) shall not be less than 90% by weight, and not more than 5% by weight shall pass through 1.00 mm IS SIEVE.

(OR)
PARTICLE SIZE (GRANULAR)

90% of the material shall pass through 4 mm IS SIEVE and be retained on 2 mm IS SIEVE. Not more than 5% shall be below 2 mm IS SIEVE.
