RKB series: Multi purpose mixer and best mixing qualities

Application Range:
RubergConical Ribbon Blenders are designed for producing critical dry material mixtures. Slow rotating mixing tools ensure gentle product treatment.The shape of the funnel offers maximum scope to arrange a number of process connections on top of the mixer as well as ensuring a residual free emptying of the vessel. Located on load cells

Ruberg Conical Ribbon Blenders combine the functions of precise weighing and premixing of small- and medium sized components. Ruberg Conical Ribbon Blenders are made of stainless or special steel with high quality surface treatment.

Option - one large inspection door arranged laterally enables convenient manual cleaning. For fully automatic operation there is a highly developed CIP system available.

Operating method:
The ribbon mixing tools close toleranced with the mixing chamber lifts large volumes of material upwards across the outside wall and releases it downwards into cavities developed in the middle. Simultaneously material is horizontally distributed by the mixing arms and is optimally homogenized and discharged through the central outlet at optimum mixing quality.

Design Variations

• Approved shape of funnel, various sizes available
• Various materials and surface treatments available depending on product characteristics
• Maintenance free shaft sealing
• Free-floating, bearing-suspended mixing spiral
• Large inspection and maintenance door
• Weighing system and metering device
• Cutting rotor for breaking down of agglomerates
• Liquid addition by ISR system
• Heating or cooling jacket with insulation

For most critical mixing requirements of all production areas. For simple plant technology and ergonomical logistics regarding handling of existing containers. Using adapter pieces various container sizes and designs can be used.

The closed mixing system works without product restraints and can be cleaned conveniently.

LCM series: Product development micro batches

Application Range: Ruberg-Laboratory Batch Mixers

Operating method:
Quantities of products are collected in commercially approved barrels and docked to the mixing chamber. The complete unit is swivelled into the working position and the process started. Variable rotational speeds circulate large volumes of the product components in a gentle mixing action. Simultaneously material is horizontally distributed by the mixing arms. Within a short period of time the optimum mixing quality is achieved and the unit can be swivelled back into base position. The homogenized product is emptied completely into the container which is then undocked and transferred to the further processing.

have various applications for laboratories or small production quantities, including development of recipes and product development of pure dry mixes, addition of liquids into dry materials and pure liquid mixes. Also possible is a gentle product treatment for homogenization of sensitive material through to breaking down of agglomerates by using a cutting rotor. Further options of processing are heating and vacuum mixing. Reproducible trial and comparison mixes are parts of product development and quality assurance which can not be neglected.

Design Variations:

• Stable desktop model
• Mobile unit arranged on movable support
• Cutting rotor for breaking down of agglomerates
• Addition of fluids by ISR system
• Heating or cooling jacket with insulation
• Complete automation for production
• Computer controlled with report

Of various designs for most critical mixing requirements of products of different density, grading range, and consistency. For highly sensitive product applications e.g. pharmaceuticals, chemicals and food industry to bulk goods e.g. building material and animal feed industry.

DLM Series: Powerfully and Continously into the Future

Machine sizes:
From 0,5 to 750 m3/h throughfeed performance with a mixer chamber volume of 70 to 4.250 litres. In corresponding high-quality stainless or special steels. Individually adjustable mixer tools make possible a variable residence time of the product in the mixer chamber. Installation horizontal or at a pitch of up to 45°. Low operating costs through robust construction. Control flaps over the whole mixing length for cleaning and maintenance. Emptying efficiency >98% depending on the design and mixer tools.

Operation:
In the inlet area the continuously fed product is taken up and transported by the first mixer tools. Alternating compressing and expanding working ranges homogenize the mixture. On the basis of the adjustable angles for the mixer tools and the circumferential speed adjusted to the mixture the residence time of the product in the mixer chamber can be varied. The frequent contact of the product with the mixer tools and the speed adjusted to the mixture cause e.g. powders and liquids to agglomerate. The fully developed technology and robust design guarantee faultfree operation with a long service life.

Variants depending on the process technology:

• Protection against wearing by cast basalt lining
• Product encrusting prevented by wear-resistant nonstick lining of the mixer chamber
• Facility for the addition of liquids, vapours, gases and highly viscous media into various operation zones of the mixer tools
• Continuous throughfeed weighing, with an impact scale, for determining the throughfeed performance as well as for the fully automatic metering of further additives
• Process monitoring via integrated sensors (power, temperature, moisture, etc.)
