Frequently Asked Questions
A Ploughshare Mixer is often suitable for materials that tend to agglomerate.
Its plough-shaped mixing tools generate intensive circulation of the material, while optional high-speed choppers can break up lumps and agglomerates during mixing.
The final selection should be based on the material characteristics and process requirements.
Vortex mixers are designed for a wide variety of powders, granules, and powder-liquid mixtures.
Typical applications include chemical powders, food ingredients, pharmaceutical powders, animal feed, dry mortar, ceramics, battery materials, fertilizers, pesticides, minerals, refractory materials, and other bulk solids. The actual mixer configuration should be selected according to the physical and chemical properties of the material.
Vortex manufacture a wide range of industrial powder and bulk solids mixing equipment, including:
- Horizontal Ribbon Mixers
- Ploughshare Mixers
- Double Shaft Paddle Mixers (Paddle Mixers / “No-Gravity” Mixers)
- Conical Twin-Screw Mixers
- Vertical Screw Ribbon Mixers
- Double Cone Mixers
- V-Type Mixers
- 3D Motion Mixers
- Customized mixing systems and complete mixing lines
The most suitable mixer depends on your materials, production capacity, mixing ratio, required mixing time, and process conditions.
Mixer capacity should be evaluated using both the total vessel volume and the effective working volume. The required volume depends on material bulk density, batch weight, filling ratio and the mixing principle of the selected machine. A mixer should not normally be filled to its total geometric volume because sufficient space is required for material movement and effective mixing. For this reason, selecting a mixer based only on vessel volume can result in an unsuitable configuration.
The appropriate industrial powder mixer depends on several factors, including:
- Material characteristics
- Bulk density
- Particle size
- Required mixing uniformity
- Batch size or production capacity
- Moisture content
- Whether heating or drying is required
- Whether liquid addition is required
- Required discharge configuration
- Production and automation requirements
Vortex provides different powder mixer designs so that equipment can be selected according to the specific process requirements.
Vortex powder mixer selection depends on several factors, including:
- Material type and characteristics
- Bulk density and particle size
- Material flowability
- Moisture content
- Viscosity
- Mixing ratio
- Batch size or required production capacity
- Whether liquid addition is required
- Required mixing uniformity
- Temperature, pressure, vacuum, or other process requirements
Vortex engineers can recommend a suitable powder mixer based on your material and process requirements.

Conical Screw Mixers -About Equipment for Handling & Processing Bulk Solids
Conical Screw Mixers (also called Nauta Mixers) make use of a conical chamber with a vertical screw that mixes the powder or substance.
Working principle
First step is charging of mixer from the top, manually or vide pneumatic or mechanical conveying. After the mixer is charged the mixing process starts.
The mixing is carried by means of 3 distinct intermixing actions:
The screw agitator, turning on its axis, produces a lifting action as it spirals the materials in an upward flow.
At the same time, orbiting the tank, the screw removes material away from the wall and deflects it into the centre of the tank.
Material lifted by the screw gravitates downward, thoroughly intermixing with material being spiraled upwards.
The typical speed of the central screw is 70 to 80 Rpm. The Tip speed can fluctuate from 1 to 3 m/s. The result is most intimate intermingling of all ingredients. The mixing time is depending on product characteristics, mixing accuracy and batch size
Example
Conical Double Screws Mixer (also called Nauta Mixers) consists of driving part, screw agitator and reverse cone cylinder. The agitator are two asymmetrically helixes. They rotate around their own axes and
