Examples include: using hammers to remove or install bearings, dropping or striking assembled equipment, and a bearing onto a shaft by applying force to the outer ring. Install bearings by applyingLow vibration means less noise, wear and tear. The flaking mill and drive motor are mounted on a common base supported by vibration mounts resting on the floor. No vibrations are transmitted to the building structure. Noise is kept at a minimum, contributing to a more pleasant working environment.

    3.1.1 Storage - Protect fans against weather, excess heat, damp and dust. Particularly cover and protect bearings, shaft and motor. Inspect fan periodically and in the case of ball or roller bearings rotate weekly to prevent brineling of races. Do not store near vibrating machinery or fan bearings might suffer damage of a similar nature.The dilution air fan is powered by a 700 HP WPII Baldor•Reliance motor. This fan pulls heat from the clinker cooler to help dry raw materials in the raw mill using the hot gas generator. An 800 HP Baldor•Reliance TEFC (blower assist cooled) motor is used on the coal mill drive that grinds the coal used to fire the kiln.
