How to solve the problems of tower sticking and flattened particles during high-temperature granulation in tall towers
Thread Content
When the temperature is high, the particles coming out of the tower do not cool properly; they tend to stick to the collection device at the bottom of the tower, and they are also prone to becoming flattened and damaged. Do any of you have any good solutions? Should we increase ventilation inside the tower, or use some other approach? Also, what is a suitable cycle length for minor maintenance on high-tower compound fertilizers (8-10 hours)? We generally don’t stop the operation due to equipment failures or blockages; often, it runs for over a month without any maintenance.
Could I have your WeChat? WeChat says.
First of all, I’m really envious of your uptime rate. Regarding the issues you mentioned, we are also looking for effective solutions (such as reducing the granulation temperature, using appropriate nozzles, and mixing rokipotassium with manheim potassium) in order to lower the output per working hour. I’m not sure what the method of collecting material is at the bottom of the tower; those two wings can damage the particles. Communicate more.
Our car usage rate isn’t as high as you might think: lol, it’s often more than a month between uses. We are currently using a tray with a spiral material collection device. Are your granulators differential or extrusion type?
The tray equipped with a spiral collection device causes minimal damage to the particles during the collection process. We use two types of granulators: the Baoji type and the Batian type.

Lower the temperature of the mixing tank, reduce the processing time per unit, and add a small amount of slurry conditioner (to reduce slurry viscosity and increase fluidity).
What types of slurry conditioners are available? How effective is it? How much does it cost per ton of fertilizer?
The cost per ton of fertilizer is 20 yuan, and the effect is quite good. For example, formulations with very poor flow properties such as those for producing urea-based products with a viscosity of 317
Is it called a slurry emulsifier? I heard there’s such a thing.
No, it’s a type of surfactant; we use it as well
