Frequently Asked Questions

Which mixer is suitable for materials that tend to agglomerate?2026-10-26T16:39:55+08:00

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.

What materials can Vortex mixers process?2026-10-16T09:04:44+08:00

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.

What types of industrial mixers does Vortex manufacture?2026-10-14T15:53:23+08:00

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.

How do I calculate the capacity of a vortex mixer?2026-10-13T08:55:05+08:00

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.

How do I choose the right industrial powder mixer?2026-10-10T09:54:18+08:00

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.

How to choose the right powder mixer?2026-09-23T15:48:06+08:00

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.

Do you manufacture controls for your mixers?2021-10-18T15:42:51+08:00

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.

Is the your mixer machine easy to install?2021-10-18T15:40:34+08:00

Yes, we normally test the mixers before they are shipped and mark out the wire need to connect on the control box.

What types of mixing equipment does the company specialize in?2021-10-18T15:36:40+08:00

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.

Do you sell to our country?2021-10-18T15:31:19+08:00

We sell across the world, our cusotmers distribute 5 continents.

Ideal Design of Mixing Equipment for Vacuum Drying

Vacuum drying Vortex conical screw blender/dryer are ideal design for vacuum drying with a wide range of applications in both solid and liquid forms, such as powders, pellets, granules, fibers, slurries, pastes and etc. Conical screw vacuum drying blender features of a gentle-action auger screw that gently lifts batch materials updates as batch materials orbit around the wall of conical vessel. Materials being carried to the top of batch then cascade slowly back down into regions opposite the moving auger screw. Meanwhile, the double auger screws rotation and keep the revolution, while the batch materials get a completely and totally mixing result. Thus, the constant exchange of materials between the heated sidewalls and center of the conical screw blenders accelerate the drying process.

A common issue in agitated dryers is the risk of product attrition or generation of fines. This concern is well minimized in a conical screw blender/dryer because the blending action is complete and thorough but very low impact. During the drying circle, hot water, thermal oil, or steam is recirculated through the vessel jacket. Due to lower processing temperatures made possible by the vacuum environment, there is a reduced risk of creation hot spots on the vessel walls where products could bake.

Pictured is 100L jacket-type conical screw blender, both conical vessel and jacket are made of stainless steel 304 polished to 240 grit. Vortex conical screw blender available in many size from 50L through 10000L. As conical screw blender/dryer do not require a bottom support bearing to keep steady so discharge of batch material is virtually 100% complete. This “unsupported screw” design also simplifies cleaning and maintenance.

To propose you a suited conical screw blender/dryer, please feel free to contact us via info@incmachine.com with the names and bulk densities of mixing weight, mixing weight for per batch. Our sales engineer would like to send you official offer.
