How to increase the output of spray granulation
Thread Content
Our company’s spraying workshop is capable of producing 400 tons of compound fertilizer per day; I would like to mention this production volume. Guys, please help. Where should I start?
1# liyi790 First, we need to see what size your equipment is. Most spray granulation plants have a capacity of 100,000 tons; the owner in question has a daily production capacity of 400 tons, which is already quite good if it’s 100,000 tons.
Raising awareness improves the operational skills of operators, and it also facilitates equipment upgrades. It seems that the constants related to spraying aren’t very high
You should first identify where the bottleneck restricting your production capacity lies, and then take appropriate action.
It is necessary to start by improving the primary granulation rate of the granulator.
Is the pelletizer used by the poster a 4.25 model? If so, its production capacity is basically at its limit.
To perform a heat balance calculation for the dryer, increase the spray volume once the heat load is sufficient; when doing so, pay attention to the granulation effect. There are three methods of granulation in spray granulation: self-granulation, coating granulation, and bonding granulation, among which coating granulation is the best.
One can view my previous discussions on spray granulation in this forum from a few years ago: there are three types of balances in spray granulation, not just material balance and heat balance, but also particle balance! By focusing on these three aspects, I believe some results can be achieved. Slightly increase the granulation rate, slightly raise the flue gas inlet temperature and lower the exhaust gas temperature at the end of the kiln, as long as dew formation and blockages do not occur. Reduce the moisture content of the raw materials fed into the granulator.
