Coal Fired Power Plant Case Study: Coal Crusher Gearbox ...

The Problem - Coal fired power plants typically operate several ball mills or coal pulverizing mills to crush the incoming coal to the optimum size for combustion. This means that each power generation unit has five or six mills. The gearboxes that run these coal mills are usually lubricated with high viscosity oil, such as ISO VG320 or ISO VG460.

Lubrication Checkup: Gearbox Overheating - Efficient Plant

Dec 19, 2013 · Judging by your description of the gearbox to the touch of a hand, I estimate its temperature to be around 150 F (or 65 C)—the approximate temperature when the hand has to be lifted within three seconds of touch. That's too hot, especially since the normal "warm to the touch" temperature would be approximately 104 F (or 40 C).

How are gears & gearboxes used in wind turbines?

May 18, 2011 · Conventional turbine design uses a gearbox to speed the slow, but high-torque power in a main shaft to a higher rotational speed useful to the generator. Conventional utility-scale wind turbines often use three- stage gearboxes. The first stage is often a planetary drive because that design handles high torque best.
