The vertical homogenizer, also called split-type homogenizer, is driven by a motor to make the rotor and matched stator run at high relative speeds. Processed materials flow downward in a spiral pattern under their own gravity or external pressure generated by a pump.
Driven by the high tangential velocity and high-frequency mechanical motion of the rotor, materials pass through the narrow gaps between stator and rotor. They undergo intensive mechanical shearing, hydraulic shearing, centrifugal extrusion, fluid friction, impact, tearing and turbulence. This process produces solid-liquid suspensions, liquid-liquid emulsions and gas-liquid foams. With proper stabilizers and processing techniques, immiscible solid, liquid and gas phases are rapidly homogenized, finely dispersed and emulsified. After continuous high-frequency circulation, stable and high-quality final products are obtained.
Featuring a vertical split structure, this homogenizer supports long-term continuous operation. It rarely suffers from shaft deflection. Routine maintenance and part replacement are simple: only the drive belt needs to be replaced, which can be done by general operators.
The horizontal homogenizer also relies on a motor to drive the rotor and stator for high-speed operation. Raw materials are conveyed downward spirally by gravity or pump pressure. With additional external kinetic energy, different materials are fully blended into a uniform mixture.
Working on the same rotor-stator principle, materials inside the clearance experience comprehensive shear, extrusion, friction, tearing and turbulent flow to form suspensions, emulsions and foams. Combined with stabilizers, multi-phase materials achieve rapid homogenization and fine dispersion. Repeated high-frequency cycles ensure consistent product quality.
This horizontal direct-coupled unit is built for long-hour operation, but it is prone to shaft eccentricity, resulting in unstable running conditions. Replacing damaged emulsifying heads and drive shafts requires disassembling internal components, which must be handled by professional technicians.
Structurally, the vertical homogenizer adopts belt transmission. Its running speed can be increased 3 to 5 times compared with the original motor speed. For this reason, it delivers far better performance in dispersion, emulsification and homogenization than the horizontal counterpart.
