1. Paddle type agitator
Leaves of paddle type agitator are made of flat steel, being welded or fixed on the wheel hub by bolt, the leaf number is 2, 3 or 4, blade shape can be divided into two kinds of straight blade type and folding blade. The paddle type mud agitator is mainly used for the circulation of the fluid, and also can be used for the mixing of high viscosity fluid. It can promote the exchange of upper and lower fluid, and instead the high-price screw belt impeller .
2. Propulsion type agitator
The propulsion type agitator is used in low viscosity fluid, and the turbulence of fluid is not high when mixing, but the circulating quantity is large. The propulsion type agitator is simple in structure and easy to manufacture, and is suitable for the occasions where have the low viscosity and large flow rate, and it has the good performance of the cyclic performance and the shearing action is not so good. It belongs to the circulation type agitator.
3. Turbine type agitator
The turbine type agitator belongs to the low viscosity fluid flow mixer, it is the most commonly used type of agitator in the mixing of drilling fluid. It can effectively accomplish almost all of the stirring operation, and can handle a wide range of fluid viscosity. The turbine type agitator has a large shear force, which can be used to make the fluid micelle be very fine. It is suitable for the mixing of low viscosity liquid to medium viscosity fluid and the liquid-liquid dispersion, liquid and solid suspension.
