A mud agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.Drilling Fluids Processing Handbook

Types of agitator impellers
Radial Flow Impeller. Figure 1 shows a radial flow created by the impellers wherein the circulation is predominantly horizontal. Axial Flow Impellers. Figure 2 shows an axial flow created by the impellers wherein the circulation is predominantly axial fluid movement.
