Roller mills can typi- cally handle raw materials with an aggregate moisture of 15% while ball mills are limited to about 8%. Ball mills used for drying should be air-swept using air velocity of 3-4M/sec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.
A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.
