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

Recommended Blending Equipment for Nutraceuticals
Application Summary:
Nutraceuticals are supplied in many forms including tablets, capsules, drink mixes and powders.
Faced with an increasing demand for higher processing standards, nutraceutical companies are intensifyinng efforts on diligent equipment selection and good manufacturing practices. One of the key considerations is proper blending of the active ingredient(s), excipients, fillers, flavors, colors, lubricants and other additives to ensure consistent product quality, efficacy and purity.
Vortex Ribbon Blenders
Dry blending is an indispensable operation in the manufacture of multivitamins, sports supplements, herbal extracts, meal-replacements, green food powders and other nutraceutical products. Many supplement formulators and contract manufacturers accomplish this process on Ross Ribbon Blenders. Ingredients are loaded into a U-shaped trough and mixed by a horizontal
agitator consisting of inner and outer helical ribbons. The position and precise pitch of each ribbon produce a well-balanced axial and radial flow pattern, promoting fast and thorough mixing. Maximum tip speeds are approximately 300 ft/min but with variable speed control, the blending action can be finetuned and optimized according to the characteristics of a particular recipe.
Benefits of Vortex Ribbon Blenders:
RB ribbon blender and mixer
- Flush valves, end wall scrapers and close tolerances between the outer ribbon and trough eliminate “dead zones” where product can collect. Interior stainless steel surfaces are also well-polished and each weld is “radiused” to prevent material buildup.
- Direct drive design is standard on all Ross Ribbon Blenders. Unlike older belt-driven blenders which are noisy and prone to slippage, direct-driven Ribbon Blenders are more reliable and require less maintenance. These utilize compact gearmotors (one-piece motor reducers) and inverters, providing electronic speed control, soft-start capability and overload protection.
- Different duty models are available for accurate sizing according to bulk density. Standard capacities range from ½ to 1,000 cu.ft. Vortex Ribbon Blenders can be customized to include pneumatically operated covers, bag dump stations, special ports and discharge valves, interchangeable paddle agitator, liquid spray bar, load cells, vacuum design, high speed choppers, PLC recipe systems and many other options.
