The coal pulverisers at power generation plants grind the coal to a fine dust before it is mixed with warm air and blown into the furnace where it ignites in a similar way to if it were a gas. The replacement worm gears can be manufactured from original drawings or by employing Renold Gears' unique method of taking a profile from a worm shaft ...

Planetary gearboxes increase the torque by the stage of reduction ratio, making it possible to run the motor at a higher and more efficient speed. The inertia reflected back to the motor is reduced for increased stability. Using a planetary gearbox allows machine builders to utilize smaller, less expensive motion control packages.
