The working principle of the conical powder mixer is to achieve uniform mixing of materials through three-dimensional composite motion and multi-directional convection mixing mechanism. The core lies in the combination of the motion of the spiral agitator and the unique design of the conical container. The following is a detailed step-by-step explanation:
1. Basic structure linkage
Conical container: fixed (some models can rotate), with a conical outlet at the bottom to reduce material residue.
Spiral agitator:
Single or double spiral: installed in the center or eccentric position of the cone, controlled by the drive system.
Motion mode: The spiral rotates around its own axis (high speed) and revolves around the center line of the cone (low speed) at the same time, forming a planetary motion trajectory.
2. Mixing process decomposition
(1) Lifting stage
Rotation effect: The spiral blades rotate at high speed, lifting the bottom material vertically upward along the spiral surface, similar to the "screw conveying" effect.
Revolution assistance: The revolution of the spiral expands the lifting range of the material and covers the materials in different radius areas of the cone.
(2) Diffusion stage
Top scattering: When the material is lifted to the top of the cone, it is scattered from the end of the spiral due to centrifugal force, forming a "waterfall effect".
Gravity sedimentation: The scattered material falls freely under the action of gravity, and particles of different densities and particle sizes penetrate each other during the sedimentation process.
(3) Convection circulation
Bottom convergence: The falling material is re-accumulated at the bottom of the cone, captured and lifted by the spiral again, forming a circular flow.
Shear mixing: The friction between the spiral blades and the material and the inter-layer velocity difference inside the material generate shear force to break the agglomeration.
3. Three-dimensional mixing mechanism
Radial mixing: The spiral revolution diffuses the material from the center to the cone wall, and then brings it back to the center through self-rotation.
Axial mixing: Vertical lifting and sedimentation realize the exchange of upper and lower layers of materials.
Tangential mixing: The vortex generated by the spiral rotation causes the material to move horizontally.
4. Influence of key parameters
Speed control:
Spindle speed: affects the lifting efficiency and shear strength (too high may cause material heating or damage).
Revolution speed: determines the mixing range (too low will reduce the diffusion effect).
Loading capacity: usually 30%-70% of the container volume. Overloading will limit the material throwing space and cause uneven mixing.
Mixing time: generally 5-20 minutes, which needs to be optimized through experiments according to the material characteristics.

Q1: What materials are suitable for mixing with a conical powder mixer?
Suitable for powders and particles (such as chemical raw materials, medicines, food additives, battery materials, etc.), especially for materials with large density differences, fragile or slightly sticky.
Not applicable: strong viscous pastes, high-humidity agglomerated materials (special design required).
Q2: How long does the mixing time usually take?
Conventional materials are about 5-20 minutes, which needs to be determined through experiments. High uniformity requirements (such as the pharmaceutical industry) may be extended to 30 minutes.
Q:3 What is the maximum load capacity of the equipment?
The recommended load capacity is 30%-70% of the container volume (overloading will cause uneven mixing).
Q4: How to choose a single or double spiral model?
Double spiral: suitable for materials with high uniformity and large density differences (such as lithium battery materials, medicines).
Single spiral: suitable for ordinary mixing needs, lower cost.
Q5: Is an explosion-proof design required?
If flammable and explosive dust (such as metal powder, certain chemicals) is mixed, it is necessary to select an explosion-proof motor + static elimination device, and ensure that the equipment is grounded.
Q6; How to choose the material?
Stainless steel (304/316L): Food, pharmaceutical industry (in compliance with GMP standards).
Carbon steel + coating: General chemical, metallurgical industry (select carbon steel lining plastic when corrosion protection is required).
Q7: What should I do if there is a lot of material residue after mixing?
Check whether the gap between the spiral blade and the bottom of the cone is too large, or whether the bottom valve is not sealed tightly.
Polyurethane scrapers can be installed or the discharge port design can be adjusted.
Q8: What may be the cause of abnormally high noise during operation?
Common causes:
Bearing wear (need to be replaced).
Friction between the spiral blade and the cylinder wall (adjust the installation position).
Metal foreign matter is mixed in the material (stop the machine for investigation).
Q9: Can the material be heated or cooled during mixing?
Optional jacket design, through steam/thermal oil heating or cold water circulation temperature control, suitable for scenes that require dry or temperature-sensitive materials.
Q10: How often do you need to lubricate the equipment?
Grease the bearings and gears every 3-6 months (refer to the manufacturer's manual for details).
The cycle needs to be shortened for high-frequency use or high-temperature environments.
Q11: How to clean the inside of the equipment?
Dry cleaning: Use a soft brush or compressed air to clean the residue.
Wet cleaning: Some models support CIP (cleaning in place system), directly pass the cleaning agent to rinse.
Q12: What should I do if the spiral blade is severely worn?
Check the blade thickness regularly, and replace it if the wear exceeds 30%.
In high-wear scenes, wear-resistant alloy blades or tungsten carbide coatings can be selected.
Q13: Possible reasons for uneven mixing?
The material properties are too different (such as density, particle size).
The loading capacity exceeds the recommended range.
The speed setting is unreasonable (the rotation/revolution speed needs to be adjusted).
Q14: What should I do if the equipment does not rotate after starting?
Check whether the power supply is normal.
Check whether the motor overload protection is triggered (may be caused by material jam).
Contact the manufacturer to check the reducer or transmission parts.
Q15: How to deal with the blockage of the discharge port?
Use a soft stick to clear it after stopping to avoid metal tools scratching the inner wall.
For sticky materials, anti-stick coating can be sprayed on the inner wall of the discharge valve in advance.
Q16: Does it support customized non-standard sizes?
Most manufacturers provide customized services, which can adjust the volume, aspect ratio, stirring form, etc., and need to provide material characteristics and process requirements.
Q17: How long is the life of the equipment?
Under normal use and maintenance, the life of core components (such as spirals and drive systems) can reach 8-10 years, and wearing parts (seals, blades) need to be replaced regularly.
Q18: How to verify the mixing uniformity?
Sampling test method: Take 5-10 samples at different locations, test the content of key components, and calculate the coefficient of variation (CV value ≤5% is qualified).
Q19: What are the safety taboos during operation?
It is forbidden to open the inspection door or reach into the equipment during operation.
Anti-static clothing must be worn when operating in explosion-proof areas, and the equipment must be reliably grounded.
Q20: Does the equipment comply with GMP/CE certification?
Special models for the pharmaceutical/food industry are usually GMP certified, and exported equipment must comply with CE or ATEX explosion-proof standards (needs must be clarified before purchase).
