Composed of a U-shaped container, ribbon mixing blades, and transmission components.
The elongated U-shaped cylinder structure ensures low-resistance movement of the mixed materials (powder or semi-fluid) inside the cylinder.
Forward and reverse rotating ribbons are mounted on the same horizontal shaft, creating a low-power, high-efficiency mixing environment. The ribbon blades are usually designed in double or triple layers — the outer ribbon moves the material from both ends toward the center, while the inner ribbon moves the material from the center toward both ends. This flow pattern generates more vortices, accelerating mixing speed and improving mixing uniformity.
The horizontal ribbon mixer is a new type of mixing equipment featuring high efficiency, high uniformity, high loading capacity, low energy consumption, low contamination, and minimal material breakage.
This product has a wide range of applications. It can mix powder with powder, powder with liquid, and is especially suitable for mixing pasty, viscous, or heavy materials (such as putty, textured paint, and metal powder). It is widely used in industries such as pharmaceuticals, food, pesticides, dyes, chemicals, plastics, ceramics, coatings, putty, and mortar.
Mixing is an indispensable production process in modern industry. With the continuous development of China’s industrial sector, mixing systems and mixing equipment are becoming increasingly advanced. Mixing spans across almost every industrial field, including chemicals, food, building materials, pharmaceuticals, and fertilizers. Nearly every product we use daily involves at least one mixing step during its production.
A mixer, also referred to as a mixing machine, serves two main purposes: physical mixing and chemical-assisted mixing.
Physical mixing is purely a mechanical process in which two or more materials are blended together through agitation to produce a uniform mixture.
Chemical-assisted mixing refers to mixing accompanied by chemical reactions, where the main objective is to ensure thorough chemical interaction, while physical mixing enhances material contact to promote reaction efficiency.
In the strict sense, mixing refers to the physical combination of two or more substances without any chemical change. Mixing can be classified into gravity (free-flow) mixing and mechanical mixing:
Gravity mixing relies on the natural movement of materials and internal friction to achieve a uniform blend.
Mechanical mixing uses mechanical force to drive the mixing process until homogeneity is reached.
In general, gas mixing is considered gravity mixing; three-dimensional mixing equipment often combines both gravity and mechanical mixing principles; and in all mechanical mixing processes, the mixing container itself remains stationary.
For powder materials, a pneumatic large-door discharge structure is adopted, featuring fast unloading with no residue. For fine-particle materials or semi-fluid materials, manual butterfly valves or pneumatic butterfly valves are used. The mixer can be equipped with a heating or cooling jacket. Heating options include electric heating and heat-conducting oil heating. For cooling, chilled water can be directly injected into the jacket, which has a large heat exchange surface area for rapid cooling.
Small models adopt a direct connection between the reducer and the motor, offering a simple structure, high reliability, and easy maintenance. Large models use a pulley-driven cycloidal reducer; the elastic connection of belt transmission provides overload protection for the drive components.
Widely used in the mixing of:
Solid–solid materials (powder-to-powder)
Solid–slurry materials (powder-to-paste or slurry)
Applicable in pesticides, veterinary drugs, food, chemicals, biotechnology, aquaculture, ceramics, refractories, plastics, compound fertilizers, and especially suitable for mixing viscous materials.
A hydraulic coupling is a non-rigid shaft coupling that uses liquid as the working medium. It consists of a pump wheel and a turbine, forming a sealed working chamber where the liquid circulates. The pump wheel and turbine are mounted on the input and output shafts respectively, with blades arranged radially. When the motor runs, it drives the shell and pump wheel of the hydraulic coupling to rotate. The centrifugal action of the pump wheel throws the hydraulic oil outward. This high-speed liquid enters the turbine, causing it to rotate under the impact force of the oil, gradually increasing its speed and kinetic energy. Finally, the liquid returns to the pump wheel, creating a continuous circulation. The input and output shafts are connected only via the liquid, with no rigid mechanical connection.
If the load is too large and the output shaft stops, the input shaft can still rotate, preventing damage to the prime mover. When the load decreases, the output shaft accelerates until its speed is close to that of the input shaft, reducing the torque transmission to near zero.
Motor and equipment protection — Prevents overload damage. When the load is excessive and stalls the machine, the working liquid is expelled through the fusible plug, disengaging the drive from the load, protecting the motor and equipment. In operation, any speed difference caused by shock loads is absorbed by the coupling.
Smooth load starting — Effectively isolates impact and torsional vibration during equipment startup and operation.
Generally not compatible with variable-frequency drives, making speed regulation ineffective.
May result in multiple energy transfers, causing power losses and no improvement in startup performance.
Does not allow inching (jog control) of equipment.
In case of overload, splashing of working liquid may pose safety hazards to operators.
