Many know that when dealing with highly viscous materials that require mixing, the helical blade mixer is often chosen. However, it's not that a high viscosity automatically calls for a helical blade mixer; this is a small misconception about choosing a helical blade mixer.

Shandong Dineng Environmental Protection Equipment Co., Ltd. The outer diameter of the screw blade of our screw blade mixer is equal to the pitch, primarily used for mixing high-viscosity liquids (200~500 Pa·S) and pseudoplastic fluids, typically operating in a laminar flow state. The screw blade mixer is a slow-speed type, often operating in the laminar flow zone, where the liquid rises or falls along the spiral surface, forming an axial up and down circulation. It is suitable for mixing and heat transfer processes of medium to high-viscosity liquids. The common medium viscosity μ < 105 cP, with a common speed n = 0.5-50 rpm, v = 2 m/s. The outer contour of the LD screw blade mixer is close to the inner wall of the mixing tank, with a large mixing diameter, enhancing the up and down circulation of the liquid along the tank wall, making it very suitable for the heat transfer process of high-viscosity liquids.
