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 2):
The method for remodelling the surface of the granular urea, as recited in  claim 1 , wherein a specific solution of the step (a) comprising:\n heating the granular urea to 20-80\u00b0 C., so as to enhance a solubility of the granular urea in water; and then sending the granular urea into a drum comprising a shoveling board for rolling in a clockwise or counterclockwise direction; wherein a rotational speed is at a range of 1-10 revolution per minute, a rotational time is at a range of 3-10 minutes; then, enhancing the rotational speed of the drum to 10-30 revolutions per minute, slowly and evenly spraying the reconstituted liquid on surfaces of the granular urea; moments friction between particles of the granular urea and the drum, particles and shoveling board, particles and particles drives the convexes which like peaks on the surfaces of the granular urea to dissolve under a combined action of mechanical forces and water of the reconstituted liquid; waiting for 3-15 minutes; wherein no hot air is allowed during the process.
