Mixing Blade

Mixing Blade

Agitation operations are generally thought of as simple, but they are associated with various operating conditions and purposes. If an incorrect condition or purpose is selected, agitation may be totally impossible. Or, agitation may be possible only at very low efficiency.

To achieve the intended goal, selection of the best agitating blades is important.
Agitating blades vary in shape, as well as in performance.

Agitating blades have two actions, discharge action (Q) and shear action (H). The proportion of these two is said to determine the performance. In a given agitation operation, Q or H is required depending on the purpose of the particular agitation. Therefore, selection of the best agitating blades is a process of selecting an agitating blade that provides the best performance (Q or H) required for the given agitation purpose within a certain range of power. In addition, it may be important to scale up the equipment to suit the purpose based on past achievements and experimental results. With Techmix, these consideration points are kept in mind in selecting agitators.
