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.

How to Avoid Segregation Problems in Your Blending Process?

George Knight is having some headache those days. As the leader in charge of production department, he is perplexed by the de-mixing problem during the mixing process. “We use a tumble blender for our mixing process. It came to our attention that when the mixing time is long, they can undo the mixing results.” said George when he came to ask help from Vortex Machinery Technology, a well-known mixing expert in the industry.

Most liquid blends don’t degrade over time as mutually soluble liquids form a stable blend. However, dry mixtures do have a tendency to segregate. “Particles have different sizes, shapes, and densities. When the particles are in motion (as in mixing), the differences cause the particles to segregate.” explained Cary Gardner, engineer from Vortex MT.

The ingredients are usually loaded in batches in a tumble blender which often forms stratified layers in the vessel. When the unit starts tumbling, its symmetrical rotation creates a nonrandom mixing pattern. This pattern, when combined with the different trajectories caused by various particles, can segregate the particles in a pattern different from that formed by the layers during loading. To avoid this segregation in the later mixing stages, the best solution is to use a tumble blender for relatively short mixing times. A tumble blender can be designed to provide asymmetrical rotation to minimize demixing caused by trajectory segregation. For example, a V-blender can have one extended leg and a double cone mixer can have offset cones; by using such designs, you can shorten mixing times, improve mixing quality, and limit further segregation.

Vortex MT helped George solve his problem by designing a processing line with as few transfer points as possible between mixing and final step. There is no use of free-fall chutes or drops in this processing line. By using controlled-discharge mass-flow patterns to help remix the material, George does not have to worry about the segregation problems in his process.
