What are the large-scale units in ammonia nitrate plants?

Besides the nitric acid four-in-one unit, what other large or important rotating equipment is there? Thank you.
What’s the extra thing that 4in1 has compared to 3in1?
First, to answer the question from above: the “four-in-one” unit is the core equipment for the “double-pressure” nitric acid production method; it has an additional nitrogen oxide compressor compared to the “three-in-one” unit, which is used for re-pressurizing the absorbed substance. *For the large-scale equipment in AO acid AN plants, it depends on the process used; for example, if vacuum crystallization is employed, vacuum pumps and crystallizers are required, while for high-tower granulation, granulation fans and drying drums are needed. However, no matter what process is used, one large piece of equipment is essential: the finished product conveyor belt.
