Pneumatic conveying and storage of urea Keeping moisture

Urea is produced in prills, granules, flakes, pellets, crystals and solutions, but it is traditionally marketed as prills or granules. The choice of the commercially preferred form is normally associated with its application, solubility, crushing strength and free-flowing behaviour.
