How can the drum granulation process be converted to semi-automated or automated?

In our factory’s drum granulation unit, the operator sits at the outlet of the granulator and adjusts the amount of steam based on the moisture level and balling efficiency of the material. The working conditions are quite harsh, and we would like to convert this process to a semi-automatic or fully automatic one. It was considered to install cameras at the outlet of the granulator so that operators could control the steam volume remotely, but this idea was abandoned due to issues such as changes in the amount of material returning, the humidity of the material, and inaccuracies in viewing through the cameras. I’m not sure what good ideas everyone has; let’s discuss it together.
I think it can be controlled through the system current, as well as the currents of the crusher and the material return conveyor equipment; of course, temperature and humidity measurement devices are also needed for control. It is best to create a distributed control module controlled by a computer DCS. I heard that some manufacturers are now offering complete DCS control systems.
Reply 1# hegw: By installing a metering device at the inlet of the granulator and using electromagnetic control for the steam, it can be operated via a computer.
Reply to 3# zuo923: I was wondering if you are aware of the control performance of this DCS system, as well as the investment required to implement it.
Left Brother and Brother Huo: Help them design a more practical one. . . . . Haha, actually people are the most reliable option. The steam can definitely be reduced – it’s hard to see anything when there’s so much steam; isn’t that a waste? If you want to save money, contact me on QQ at 861062702
