Air Seals Of Vertical Raw Mills

Energy Efficiency Improvement Opportunities for the …

Raw Meal Process Control (Dry process - Vertical Mill). The main difficulty with existing vertical roller mills are vibration trips. Operation at high throughput makes manual vibration control difficult. When the raw mill trips, it cannot be started up for one hour, until the motor windings cool.

Shaft seal | KSB

The shaft seal is a sealing element which seals the rotating shaft of a centrifugal pump where it passes through the non-rotating pump casing, reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.. Pumps are specially designed and manufactured to cater for a whole range of different applications.

The rotating seal faces are fixed to the shaft, and they seal on a plane that is 90° opposed to the shaft’s axis. This effectively eliminates abrasive wear to the shaft—and in so doing, eliminates the need to replace or resurface a prime overhaul component, saving labor, time and materials during periodic overhauls.
