Sulfur packaging
Thread Content
Gentlemen, we’ve encountered a small issue recently with sulfur granulation in our equipment. Sulfur has a relatively high viscosity, causing severe sticking to steel strips. May I ask what the reason is? Is it the high temperature of sulfur? Is it still the sulfur carrying hydrocarbons that is a serious issue? Or something else. How to solve it. Thank you.
The viscosity is high; take a look at the pressure at the pump outlet It’s better when it’s larger; this reduces the speed of the steel strip and enhances the cooling effect. Reduce the amount of sulfur and observe the cooling effect. Check what effect is produced by the roller that’s being thrown.
Was a new batch of release agent used? Let’s take a look. Take a look to see if the sulfur temperature is too high or too low
Check the temperature; the temperature in the granulator should not exceed 155 degrees. If it’s too high, try lowering the temperature. More release agent can be added, and the cooling water flow rate for the steel strip can be increased.
Does \"sticky steel strip\" refer to the situation where solid sulfur on the steel strip cannot be scraped off? If that’s the case, it has little to do with viscosity; it seems more like a problem with the release agent. Check that out.
Check the steam tracing and temperature; if the sulfur is dark brown, it is likely due to high temperatures； There are many hydrocarbons or carbon deposition; the sulfur produced turns black... How is the feeding situation at the distributor? More or less compared to before? The purity of release agents varies among different manufacturers, and the amount to be used also needs to be adjusted accordingly~~
I’m planning to set up a sulfur granulation system. Please give me your guidance
