Frequently Asked Questions
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.
Yes, We can supply simple stand alone panels or automated PLC controlled systems. We normally install and test all controls on our mixers before they are shipped.
Yes, we normally test the mixers before they are shipped and mark out the wire need to connect on the control box.
We manufacture specialty mixing equipment for powder & bulk materials. Included are ribbon blender, plough mixer, conical screw mixer, twin shaft paddle mixer, V blender, double cone blender and other auxiliary equipment such as screw conveyor, quantitive auger filler.

Adding a minor ingredients
Q: To properly package our material, we add an active ingredient in less than 5 percent concentration to a carrier that acts almost like a diluent. What kind of mixer should we use, and how should we add the ingredients to get good mixing?
A: The kind of intimate mixing you’re describing typically requires a high-speed processing bar or impeller. In general, a tumble blender(double cone blender) with a high-speed processing bar will do the best job of mixing minor ingredients, but you should test your material in the unit to be sure its shear rate doesn’t degrade the particles. You can also use an impeller-driven mixer, particularly if equipped with a plow blade(that’s plow blender), for mixing minor ingredients.
The way in which you add the materials also affects the mixing quality. For best results, regardless of the mixer type, first add one-half of the bulk materials (your diluent), then add the minor ingredient (the active ingredient) into the batch’s center, then add the remaining materials (the rest of the diluent). If you add the minor ingredient first, it can adhere to the vessel walls and deposit itself in a slow-moving portion of the mixer (for instance, near a tumble blender’s axis of rotation) or material bed or get caught in a slow-moving, symmetrically rotating area of the material bed where mixing is slower.
