operating conditions for a agitation tank

Industrial agitator Wikipedia

An agitator is composed of a drive device ( motor, gear reducer, belts), a guiding system of the shaft (lantern fitted with bearings), a shaft and impellers . If the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is

Problems in Stock Agitation James Brinkley

Baffling of Tanks to Produce Top to Bottom Agitation. Tank baffles are necessary in some vertical agitator applications. Stock at consistencies above 3-3.5% is self baffling. Stock will swirl when consistency is less than 2.5-3%. If swirling starts, mixing will be ineffective, and top to bottom motion that produces complete mixing will cease.

Critical Impeller Speed for Sus Post Mixing

operating conditions and tank/agitator geometry is not yet fully understood. Several studies have proposed a linear relationship between DN js and the gas sparging rate Q g, i.e.: where a is a constant, N js is the just off-bottom suspension speed in liquid–solids systems, while N jsg is the just off-bottom suspension speed under gas sparging

Agitation Best Practices for Improved Mixing

If the agitator is to be run during boil-off due to process requirements and the product does experience an increase in viscosity, the agitator must be slowed down to at least half speed. Even when there are circumstances that aren’t ideal for mixing, agitation can be accomplished when the right operating procedures are followed.
