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.

Gentle Blending of Conical Screw Mixer

Conical Screw mixer is an ideal design for low-impact blending. Consists of conical vessel and double screws, the conical screw mixer can thoroughly agitate a wide variety of materials including powders, granules, pellets, fibers, slurries and pastes. Designed for low impact for materials, the slow-turning screws turns on its own axis while being rotated around the vessel. We called it rotation and revolution. Batch materials are lifted to the uppermost level of the cone along with the wall of vessel then cascade slowly back down in regions opposite the moving screw. This blender is not only advantageous for blending friable ingredients but also for coating solids with a minor liquid component and for vacuum drying of heating-sensitive applications.

Available in a wide range of capacity from 50L to 10,000L, vortex conical screw blenders do not require a bottom support bearing to keep the screw steady so discharge is always virtually 100% complete. This “unsupported screws” design also simplifies cleaning and maintenance, which result in easy cleaning and maintenance together. The rotation and revolution agitation are driven by two separate variable-speed motors to 80 rpm and 2.2 rpm respectively.

The conical screw blender can be supplied with a jacket for heating/cooling as well as a lump breaker for breaking apart agglomerates when needed.

Pictured is 2000L vertical screw blender with stainless steel 304 as construction material. Both interior and exterior surface are polished to simplifier the discharge and cleaning. The dished cover includes sight glass port, a charging port and quick- release clamps. On this unit, a mechanical seal is supplied for the sealing of main shaft.
