Abstract:
A method for remodelling granular urea surface, which belongs to the field of resin coated urea manufacturing technology, includes steps of: firstly sending the granular urea with a temperature of 20-80° C. into a drum comprising a shoveling board for rolling in a clockwise or counterclockwise direction; adding reconstituted liquid; dissolving convexes which like peaks and provided on surfaces of granular urea into a reconstituted liquid under a combined effect of mechanical forces and water in the reconstituted liquid; and introducing dry and hot wind, in such a manner that the urea dissolved in the recycled liquid is filled onto concaves of surfaces of the granular urea; wherein after drying is terminated, the granular urea becomes smooth and rounded; uneven surfaces of the convexes which are in a shape of peaks disappear; and the surfaces of the granular urea are shiny and show a mirror effect.

Claim (Index 12):
The method for remodelling the surface of the granular urea, as recited in  claim 1 , wherein a specific solution of the step (b) is:\n adjusting a rotational speed of the drum to 1-10 revolution per minute to avoid a high speed; wherein high-speed frictions and impacts among the granular urea, and between the granular urea and the plate of the drum cause formation of urea powder, and new surfaces with convexes and concaves are formed; introducing dry and hot wind to dry water on the surfaces of the granular urea; in such a manner that the urea which is dissolved in the reconstituted liquid is crystallized to fill the concaves on the surfaces of the granular urea; controlling a final moisture content of the granular urea to be less than 0.5%; wherein the granular urea becomes smooth and rounded; uneven surfaces of the convexes which are in a shape of peaks disappear; the surfaces of the granular urea are shiny and show a mirror effect.
