Equipment Introduction
This equipment is a medium to low-speed single-axis mixing device, typically powered by an electric motor and driven by a reducer. The mixing blades achieve high torque, propelling the material in axial or radial motion. Accompanied by shearing, diffusion, convection, and impact, the material achieves a mixing effect in a short period of time.
The structural form and mixing characteristics of agitators greatly determine the mixing effectiveness of the system. Therefore, the selection of agitators directly impacts the overall mixing performance of the equipment. Wuxi Micost is a professional in the research, development, design, manufacturing, and sales of agitators. All products provided by Micost are a blend of extensive application experience, advanced mixing technology, reliable mechanical design, and superior processing quality. Micost engineers select the appropriate agitator type, determine the size, and establish the installation method by analyzing material properties, process requirements, and various parameters to meet different customer operational needs and address real customer demands. The correct choice of agitator will provide better mixing results, operational efficiency, and mechanical performance.
The釜mounted mixer is a mixing equipment that integrates the mixer with a kettle/vessel/tank. It is commonly used in high-yield and stable production lines, enabling large-scale and mass industrial production.
Operating Principle
The impeller blades, driven by the power unit, rotate in a fixed direction, forcing the material to undergo axial and radial movements during rotation. During the mixing process, there are simultaneous actions such as shearing, diffusion, convection, and impact, which effectively enable rapid mixing and blending of the material.
Additionally, to eliminate the swirling of the liquid inside the mixing container and enhance the vertical axial circulation of the material being mixed, achieving uniform mixing throughout the entire vessel, it is necessary to add several baffles or flow guides inside the container.

Common Processes
By selecting the appropriate stirrer, through the action of mechanical external force, it can meet the process requirements for gas-liquid, liquid-liquid, solid-liquid absorption, dissolution, mixing, suspension, crystallization, extraction, and reaction, etc.
Solubility: Solutions prepared by dissolving solid or liquid substances in another liquid
Mixed: Uniformly blend various dispersed systems to prepare a new material
Crystallization: Solute precipitates in crystal form from the solution
Reaction: Materials are converted into products different from the reactants through chemical changes.
Extraction: The transfer of solute material from one solvent to another

Purpose of Common Mixing Operations, Mixing Effects, and the Relationship with Mixer Selection
Operation Objective | Recommended Blender | Characteristics parameters for evaluating the mixing effect | The importance of recirculation flow or shear force |
Gas-liquid dispersion and gas-liquid absorption | Disk-type turbines, large-blade turbines, axial-flow turbines, etc. | Distributed time, bubble specific surface area, average droplet diameter or droplet diameter distribution, dispersion uniformity | Shear force is used to split bubbles, and the recirculating flow increases the number of times bubbles pass through the strong shear zone of the impeller. |
Homogeneous low-viscosity liquid mixture (Easy-soluble Liquid Blend) | Propulsion, axial flow propellers, and turbine types | Mixing Time, Mixing Index, Flip Count, Uniformity | Increasing the recirculation flow can enhance the mixing effect, with less impact from shear forces. |
Homogeneous high viscosity liquid mixing | Anchor frame, screw conveyor, screw auger, large-blade type, etc. | Mixing time, cutting speed, flip count, evenness | The circulation flow and shear rate can both enhance the mixing effect. |
Liquid-liquid extraction | Axial propellers, straight-blade turbines, disk turbines, etc. | Extraction rate, extraction efficiency, droplet specific surface area, liquid film mass transfer coefficient, and total volume mass transfer coefficient | Shear force is used to split droplets, while the recirculating flow increases the number of times droplets pass through the strong shear zone of the impeller. |
Solid-liquid extraction | Propeller, Axial Flow Propellers | Suspended state, solid-liquid concentration, specific surface area, dissolution rate | Increase recirculation flow, enhance mixing efficiency; no effect on shear force. |
Solid-liquid suspension | Propulsion, Axial Flow Propellers, Curved Blade Turbines, etc. | Suspended state, critical suspension speed, solid-liquid concentration, specific surface area | Increase recirculation flow and enhance mixing efficiency; no impact on shear force. |
Solid-liquid dissolution | Propulsion, Axial Flow Propellers, Axial Turbines, etc. | Solubility rate, mass transfer coefficient of liquid film based on the surface area of solid particles, and overall volume mass transfer coefficient | Increase recirculation flow and enhance mixing efficiency; shearing force has a certain impact. |
Solid-liquid crystallization | Propeller, Open Turbine, Thruster with Guide Vane | Crystallization rate, grain size, and uniformity | Increase recirculating flow and enhance mixing efficiency; shear force determines the particle size of the crystal grains. |
Heat Transfer (Gas, Solid, Liquid) | Axial flow turbines, propellers, Bruma King, three-blade swept-back designs, etc. | Heat transfer efficiency, liquid film heat transfer coefficient, overall heat transfer coefficient | Increase recirculation flow and enhance mixing efficiency; no impact on shear force. |
Reactions (gas, solid, liquid) | Supply as per specified reaction conditions | Reaction time, heat transfer, mass transfer requirements, and flip frequency. For polymerization, conversion rate, molecular weight, and distribution are the main indicators. | Recirculation flow and shear force both affect the reflection. |
