| Summary: | Urea granules are one of the popular fertilizers
among synthetic fertilizer industry. Its main function is to
provide nitrogen which enhances leaf growth on plant. Urea
granules are produced from the process of granulation.
Granulation process is divided to wet and dry granulation.
Generally, there are two type of dry granulator which is
slugger and roller compactor. Roller compactor or also
known as roll press is using two counter rotating rolls to
compact raw material such as powder to become ribbons or
granules. If ribbons instead of granules are produced from
compaction, milling will be used to produce granules. It is
difficult obtain a numerical result of the process due to the variety of parameters. Therefore, this work will only
consider the parameters which are related to feeder system
and roller. The parameters include the feeding rate of
feeder, roller force, roller pressure, and roller gap size.
While powder flow to roller from feeder, overfeeding may
occurs. Overfeeding is harmful because it will cause motor
failure. To overcome this problem, the function of roller
needs to be improved. The roller will be modified and hence,
a new design will be produced. |
