Velocity Method . In fluid velocity method, the steam velocity is assumed and the line size is calculated for the required flow-rates by the following formula: Q = A x v . Where, Q = Volumetric flow-rate (m3/s) = (Steam Flow in Kg/hr * Specific Volume M3/kg) / 3600 . A = cross-sectional area of a pipe formula (m2) = D24 . v = steam velocity (m/s)

Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.

The traditional P-wave ultrasonic measurement has been used for the condition assessment of general reinforced concrete structures for a long time, but the effects of prestressing applied to concrete structures such as long-span buildings and bridges on ultrasonic pulse velocity have not been studied clearly. Therefore, this study analyzed the statistical distribution of P-wave …

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed. Result #2: This mill's ...
