WebJul 16, 2015 · However, when extra care is taken, an agitator can run at full speed during the emptying of the vessel. The caveats are: 1) it must be done quickly, 2) the liquid level should not be held at the blade level for any appreciable length of time (see above), 3) the viscosity is not increasing, and 4) the agitator should be slowed to 35% of the ... WebAgitator designed for low-viscosity products. The speeds available range from 400 to 1,800 rpm, depending on the diameter, with a typical peripheral velocity of between 3 and 15 m/s. According to the agitator's speed, the agitation system generates a high product recirculation flow rate inside the tank.
