The vertical roller mill allows a large amount of air to be passed, so the drying capacity is large the material in the grinding is in a suspended state, which increases the contact area between the material and the airflow, and the heat exchange condition is good, so the drying efficiency is high. When the ball mill grinds the wet material, due to its limited air flow through the ball mill, additional drying
