In other mills like vertical roller mills both grinding and drying take place together inside the mill by the hot gases supplied through the mill. The vertical roller mills are usually designed to have a rather constant ratio between air flow and grinding capacity. VRMs of all sizes have the same drying capacities up to 25%.
