Mixers and Gear Lubrication

Mixers include a wide variety of speeds, size and types of equipment; consequently, the lubrication of gear drives will be equally varied. Also, both enclosed and open gears will be encountered in such machines. Lacking  recommendations by the equipment manufacturer, one should  rely upon  the fact  that  high speeds in the  gears  demand low  viscosity oils and  low speeds  require high  viscosity lubricants. If the service is severe, use EP oils.
