Gas Velocity in an Air Swept Ball Mill?

− The velocity of gases calculated through mill is 1.29 m/sec. This velocity is sufficient for OPC33 grade grinding. − The separation air at separator measured as 1.22 Kg material/m 3 at circulating load of 2.52, which indicates the availability of more classifying air in the system.

how to calculate rpm of mill in cement plant

Examples include installations with 2-fan kiln systems, in cement mills or on separators. In such cases, there is a need for efficient dust pre-separation to reduce the dust burden reaching the bags. A wide central hopper is used to decrease the axial gas velocity so that a dust pre-dropping action takes place.

Jun 18, 2020· In modern cement plants, an accurate measurement of gas flow is essential for the optimised control of processes. Whether it be the correct operation of the draught fan downstream of a downcomer in order to run the kiln air flows correctly, or the tertiary air flow into the calciner process, the correct gas flow is often the key to an optimised setting of essential process parameters.
