What is a Hydraulic high speed mixer?

A disperser is a type of mixer used to rapidly break apart lumps of powdery material, uniformly distributing and wetting them in a liquid.  It is also used to dissolve soluble solids in a liquid.

How does it work?

A Hydraulic high speed mixer works on the principle of energy transfer. A disc type blade is mounted at the bottom end of the mixing shaft and rotated at a relatively high tip speed. (Tip speed is the speed at the outer tip or edge of the rotating disc. Tip speeds typical of dispersers are measured in feet per minute, calculated by multiplying the constant 3.14 times the diameter in feet of the disc times the revolutions per minute of the mixing shaft. The industry terminology for tip speed is peripheral velocity.) The solids and liquids are drawn into the rotating disc by the suction it creates. This suction usually results in a visible whirlpool from the top of the mixture down to the top of the disc. A similar whirlpool is created below the disc extending from the bottom of the tank to the underside of the disc. The whirlpools are actually two individual vortices, although common industry practice refers only to the visible upper one known as the vortex.

When the solids/liquid mixture enters the vortices and is sucked into the high-speed disc, the energy (horsepower used to drive the disc) is instantaneously transferred from the disc to the mixture. This intensively focused energy transfer creates tremendous, instantaneous velocity changes in the mixture as it progressively contacts the disc. (Think of the mixture as a series of individual horizontal layers descending downward from the top and upward from the bottom on to the face of the rotating disc.) As each layer contacts the disc it is instantaneously accelerated from the slow moving vortex into the very high speed of the disc and projected outward away from the disc and toward the wall of the tank. The rapid tearing apart of layer upon layer of the mixture is shear force, commonly referred to as shear.

What is the difference between a disperser and an agitator?

Both the disperser and the agitator will mix. Mixers are sometimes compared to pumps. The performance of a pump is usually measured in the horsepower required for its gallons per minute discharge capacity. A disperser is a high-powered, low volume pump. Considering its substantially higher horsepower per gallon requirement, a disperser is an inefficient mixer. An agitator is a low-powered, high volume pump – it is an efficient mixer. A typical dispersion application (such as dispersing pigment to make paint) requires about 1 HP for every 10 gallons compared to an agitator application (such as thinning the pigment dispersion with solvent) requires about 1 HP for every 100 gallons. Although the agitator is the more efficient pump, it does not create sufficient shear to disperse most solids into the liquids.

Moderate shear dispersers operating at about ½ the normal blade speed of high shear dispersers are sometimes used in place of agitators when some shear is required. Typically the discs have larger teeth to promote better pumping and require about 1/3 the horsepower of a high shear disperser but still 3 times more than an agitator.
