Answer 1

Taking a 50000 tons urea fertilizer plant as an example, the process of making granular urea fertilizer as follows: materials batching, raw materials mixing, materials crushing, granulation by pan granulator, urea granules drying, cooling, granular urea screening, packaging etc. the whole process includes at least eight fertilizer machines to work together.

Of course, your fertilizer yearly yield depends on the number of fertilizer machines. At the same, you should consider the raw materials of urea fertilizer and urea shape.
