Due to the high tip speed of the dispersion blade, dispersion blades are subject to wear. Depending on formulations this wear can be severe. DisperseTech offers several wear treatments.
Rapid changes in temperature of the heat transfer media can thermally shock the equipment. Typically, thermal shock is defined as changing the cooling or heating media at the jacket inlet more than 25 F per minute.
The "Rules of Thumb" present a very good starting point, for specifying disperser.
To transfer torque from the shaft to the blade, manufacturers use a number of configurations. The two most common are bore and keyway and bore and pinholes.
Of all the "Rules of Thumb" the issues resulting from this pose the most severe issues. While not difficult to calculate, Blade Horsepower does not correlate well to a simple Volume to power relation. Most disperser manufacturers rely on a modification of the agitator horsepower relationship.
Blade Speed (tip speed), measures how far a point on the outer most edge of the disperser blade travels in a given amount of time
