Cement mill Residue - Page 1 of 1

Re: Cement mill Residue. Dear Mr Jatin, You have not mentioned circuit of your mill.I assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed.

High Performance Foil Rotor Improves De-Ink Pulp Screening

Rotor speed was decreased from 16 m/s to a minimum operating speed of 11.2 m/s where the screen plugged. Note that the existing speed of the OEM rotor (of 16 m/s) was based on the OEM's own optimization work at this mill and the mill's finding that the OEM screen would plug at a rotor tip speed of 15 m/s.

INNOVATION NEWS Mills and GMDs - ABB Ltd

speed of a mill is typically in the range of 74 to 78% of the critical mill speed. This is a direct function of the mill diameter, which means that the rated speed for mills of the same diameter do not vary significantly. Therefore, the higher power density values discussed above, consequently lead to higher torque density values within these GMDs.

High-shear mixer - Wikipedia

Fluid undergoes shear when one area of fluid travels with a different velocity relative to an adjacent area. A high-shear mixer uses a rotating impeller or high-speed rotor, or a series of such impellers or inline rotors, usually powered by an electric motor, to "work" the fluid, creating flow and shear.

Shaft Vibration and Unbalance Limits – Too Stringent For ...

Aug 03, 2015· The high-speed balance limits developed by the writer in the early 1980's and currently suggested by API 684 are based on velocity of the pedestals. High-speed balance compensates for the true distribution of unbalance along the rotor, meeting a limit at maximum continuous speed but also considers the force at the first critical speed.
