Why can't steam be added to granulation?

Increase the amount of wheat in the feed formula, the temperature is only about 60 degrees when granulation, please advise why not add steam? It doesn't matter how much wheat you add, you should check your granulation equipment-- is there something wrong with the steam? Or the coal is not good, the temperature can not be raised. Check every pipe carefully! Check the quality of the steam to see if it is too hydrated. 2 check the blades of the modulator to see if there is a modulation unevenness. 3 you can consider whether the feeding speed does not match the line speed. -- that's a good thing upstairs. I agree. The possibility of the formula is very small, mainly due to equipment problems! The equipment is fine. The steam temperature can reach 75-85 °before wheat is not used. Reduce the steam pressure, use saturated steam and add some crude materials to increase resistance. -- reduce the compression ratio test-- reduce the compression ratio powder must appear. That is, the moisture content of the raw material is on the high side. There is something wrong with the steam pressure. What is the pressure to enter the tuner?
