Ball Mill Ventilation. Objectives: Cement cooling. • The purpose of cooling is even more important. • when the inlet clinker is hot. • in a closed circuit without ventilated separator. • Ventilation cooling is always preferable to water spraying. in the mill. Ex: Cement grinding with specific energy of 32 kWh/t. 95% energy into heat.
Raw mills usually operate at 7274% critical speed and cement mills at 7476%. Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2**(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.

The ball and tube mills are lowspeed 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, BBD4772,asdadasd

Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.
