Volumetric blending can be achieved using various methods such as mechanical mixers, static mixers, and fluidized beds. The choice of method depends on the nature of the materials being blended, the required mixing precision, and the scale of the operation. Mechanical mixers use rotating blades to physically mix the components, while static mixers utilize the fluid flow to achieve blending. Fluidized beds, on the other hand, use a gas or liquid to suspend solid particles, enabling thorough mixing.
