We know from our experience, that if we want to reach temperature about 75oC – 90oC in press and when we use the proper steam then it affects increase of humidity of the raw material to about 5% (for example from 12% it grows to 17%).

That’s why it is estimated that demand for steam in pelleting process is 5% of maximum production of pellet mill.

Knowing the maximal efficiency of pellet mill it is easy to count the demand for steam.
But if the efficiency of pellet mill is unknown we can suppose that the efficiency amounts to 100kg/h and multiply by power (Hp) of the main motor.

This computation gives us a maximum value, but it is always better to make bigger than smaller mistake.
From experience we also know that, if we increase for 10oC the temperature of raw material, then the humidity will increase for 1%.
