The heat to be discharged at cryogenic grinding is composed of heat, which has been introduced by the product ( Q˙feed) and the heat introduced by the drive capacity of the mill ( Q˙mill ), provided that the grinding air flow required for the operation of the mill is met by the condensing nitrogen alone. (8) Q ˙ total = Q ˙ feed + Q ˙ mill.
