Oct 17, 2016 Normally the urea size bigger than the sieve opening will leave on the screen, and discharge as oversize. In the production, there always some fine granular leave on the screen and cant go through the under screen because of some factors. Or because of the screen mesh broken, the urea size bigger than the sieve opening penetrate the screen mesh.
Granular urea is generally stronger than prilled urea, both in crushing strength and abrasion resistance. There are 2 granulation methods drum granulation and pan granulation. In drum granulation, solids are built up in layers on seed granules placed in a rotating drum granulatorcooler approximately 4.3 meters 14 feet in diameter.

Dec 29, 2016 Dry fertilizers are generally incorporated into granules. Fertilizer blends can be created by mixing individual granular fertilizer of known analysis e.g., 46-0-0, 18-46-0 and 0-0-60 in the proper ratio to create the desired blend.
Crush Strength. Crush strength, or hardness, is another key specification in soil product performance. As the name suggests, this metric indicates how much pressure is required to break a granule. Crush strength is often used as a predictor for the amount of degradation due

The required energy consumption is only 0,036 kWton of screened urea. The availability of each component in the urea granulation process needs to be as high as possible.
Dont use small or fast-moving augers to move granular urea. Urea particles are generally soft and abrasion can break the granules. Use belt conveyors whenever possible. Also, dont store urea with ammonium nitrate. When in contact, these materials rapidly absorb water when the relative humidity is above 18 percent.
