Review of control and fault diagnosis methods applied to,

Aug 01, 2015· The balls generally fill 25–30% of the cylinder volume. Grinding is caused by the tumbling action of the hollow cylinder. Coal particles get crushed between the balls as they impact each other. The specific power consumption of these mills is high. However, the ball and tube mills are robust in construction, and require less maintenance.Mill Speed - an overview | ScienceDirect Topics,The disadvantages of this type of mill are high power consumption, larger and heavier construction, greater space requirement, etc. To pulverize coal of high rank and low grindability, ball/tube mills are preferred because they can achieve high fineness, required forball and tube coal mill power consumption,Ball Tube Mill Coal Binq Mining.
