The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD-4772,
10%Ball mill, providing grinded coal for the boiler, is an important role in a thermal power plant and consumes 15 ~ 25 % of the whole energy consumption of the thermal power plant. Therefore, ensuring the efficiency of ball mill operation is of consequence for the sake of energy.

1.The raw coal from storage and conveying system come into air swept coal mill for grinding. The coal powder mass and heat transfer with 200℃~350℃ hot air. The moisture enter into flue gas from coal. Coal powder is dried by hot air. Then coal powder come to powder separator with airflow for classification.
When you're running the world's largest vertical roller mill to grind cement, you need a control and automation system you can trust to get the most out of your giant. Which is why Shah Cement Industries relies on the latest ECS/ControlCenter and ECS/ProcessExpert systems to optimise the performance of its record-breaking OK 81-6 mill.
The control problem of the ball mill of the pulverizing system of thermal power plant is one with multivariable of at least three-input-three-output. In the conventional control method, three sets of PlO set point control were used as shown in Fig. 1.
Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise most coal pulverizers currently in service at pulverized coal power plants. The grinding rolls are stationary in this design, while a worm gear drive rotates the ring (commonly known as the bowl).

Such mills are usually called pebble mills, but the working principle is the same as for ball mills. As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is correspondingly smaller than for a ball mill. ... Ball Mills for laboratories and pilot plants.
Tube or ball mills: These are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the diameter of the cylinder is greater than the length of the cylinder, the mill is called a ball mill. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill.
