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.

Where preblended wet materials are fed for dry- ing in the raw mill, silos are unnecessary. Virtually all modern raw mills incorporate closed circuits with classifi- cation in a cyclone or mechanical separator and return of coarse mater- ial for regrinding (Figure 3). Ball mill operation is described in more detail under finish milling (Section ...

Best energy consumption - International Cement Review
The principle of the new generation of vertical mill was to direct higher pressure from the grinding element to the material bed using hydraulic systems. From this approach the roller press, CKP (pre-grind vertical rollers) and Horomill ™ all developed. Raw milling. The gas-swept vertical mill quickly became the raw mill of choice.

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.

"The new seal combines the benefits of air and rubbing seals but eliminates the drawbacks common to each type," says Steve Hoeting, the seal's inventer. Made of corrosion-resistant Viton material, the new air seal is really two seals in one, notes Mr. Hoeting, combining a unique geometric shape with a novel positive air system.
The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
