Reduce pollution: pneumatic discharge valve design, residual volume ≤0.5%, reducing the risk of cross contamination.
The working principle of chemical powder ribbon mixer is based on multiple synergistic mechanisms: the double spiral convection mechanism pushes the material from the axis to the outside through the inner spiral, and the outer spiral reverses the material to the center, forming a three-dimensional convection, so that the material can quickly reach high uniformity; the axial circulation strengthening mechanism uses the spiral blades to push the material to rise along the cylinder wall and fall back axially at the top, forming a forced circulation, effectively eliminating the mixing dead corner and avoiding the stratification of materials with large density differences.
It is composed of double spiral ribbon stirring paddles, U-shaped stainless steel cylinders, variable frequency drive systems, intelligent control modules and other components to achieve efficient powder mixing and safe production.
Spiral ribbon stirring paddle: adopts an inner and outer double-layer spiral steel belt structure, the outer spiral ribbon pushes the material axially (from both ends to the middle), and the inner spiral ribbon pushes in the opposite direction (from the middle to both ends), forming a three-dimensional convection mixing.
Stirring shaft: solid shaft design, the diameter matches the cylinder volume (usually 50-150mm), and is connected to the spiral ribbon by welding or bolts to ensure strength and stability during high-speed rotation.
U-shaped cylinder: formed by rolled plate welding, volume specification 50-5000L, smooth inner wall without dead angle; bottom inclination angle ≤3°, with large door discharge port.
Drive motor: standard three-phase asynchronous motor, power configuration according to volume (2.2-37kW).
Speed reducer: gear reducer or cycloidal pinwheel reducer, transmission ratio 10-50:1, stable output torque.
Feed inlet: flange feed inlet is set at the top, which can be connected to screw conveyor, vacuum feeder, etc.;
Discharge port: pneumatic/electric discharge valve is set at the bottom center, the gate material is wear-resistant stainless steel, the switching time is ≤5 seconds, and the guide groove is used to reduce material residue.

To select a suitable chemical powder ribbon mixer, you need to consider multiple dimensions such as material characteristics, production requirements, and equipment performance. The following are specific screening points and suggestions.
Material characteristics and equipment adaptation: Clarifying the basic characteristics of the material is the key to selecting a chemical powder ribbon mixer. First, you must determine the material state and mixing type. At the same time, you must understand the physical and chemical properties of the material, including particle size and fineness, corrosiveness/wear resistance, heat sensitivity/flammability and explosiveness.
Production scale and equipment volume: Production scale and efficiency requirements directly affect equipment selection. The equipment volume is determined according to the mixing amount of a single batch, and the conventional effective volume ratio is 60%-75%. The conventional material mixing cycle is 5-15 minutes/batch. In pursuit of high efficiency, you need to choose a high-speed motor and a double-ribbon structure.
Mixing system and speed control: Mixing system design is crucial to mixing efficiency. The double-layer ribbon structure is 30% more efficient than the single-layer structure and is suitable for materials with large particle size differences; reinforced spiral blades and sidewall scrapers are required to handle high-viscosity pastes.
Additional functions and automation integration: Select additional function modules according to actual needs. The temperature control system is suitable for reaction mixing that requires temperature control, with a temperature control accuracy of ±2℃; the liquid addition device needs to confirm the metering pump accuracy and maximum addition amount; in terms of automation integration, the PLC control cabinet supports formula storage and MES docking, which is suitable for large-scale production.
The price span of chemical powder ribbon mixers is large. Small and simple models (less than 50KG, mostly made of ordinary carbon steel or 201 stainless steel) are mainly used in laboratories or small workshops, with a lower price of about US$85-690. Conventional industrial type (50KG - 1000KG, material is usually 304 stainless steel) can meet the general chemical powder mixing needs, with basic mixing and some additional functions, the price is usually 1000-5000 US dollars. The specific price will be quoted according to your detailed needs. If you need it, you can contact us at any time to get a detailed quotation!
