Ball Mill Lubrication Procedure. TRUNNION BEARING LUBRICATION. For the larger mills with trunnion bearings provided with oil seals, we recommend flood oil lubrication. This can be accomplished by a centralized system for two or more mills, or by an individual system for each mill.

Measuring Coal Pipe Flow Coal pipe flows can only be balanced and optimized when they are measured. Until you have confidence in your coal flow measurements, tuning the pul-verized coal boiler is simply guesswork. The right way to balance furnace fuel flows is to establish solid baseline performance by proper measure-

Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

SAMPLING PROCEDURE A 4 x 9 grid of sampling locations was used. Flow measurements were made for two entry widths, 4 and 5 m (13 and 16 ½-ft), and two intake flows, 2.8 and 4.7 m3/s (6,000 and 10,000 cfm). A repeat test was performed for each operating condition and results averaged for each location sampled (Figure 5).

In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
