Weighing and dosing

Weighing and dosing

Weighing and dosing bulk products into a process

It is often necessary to weigh and dose powder, amongst other bulk materials, into a process. Let’s take the addition of sugar into a mixer as an example from the food industry.

According to the recipe, a total of 150 kg of sugar must be added to the mixer. The conveyor system used requires ten conveying cycles of 15 kg each. Depending on the design of the system, delivery rates of up to 4 t / h are also possible. The accuracy of the system is 99 – 99.7% of the target weight to be achieved.

The removal from different pick-up locations is possible as well as the adjustment and storage of recipes. A quick intervention in the process is possible via the device control’s intuitive touch display. In addition, the entire process can of course also be controlled fully automatically.

The Volkmann CONWEIGH is a combined conveying and dosing system and is usually used for adding quantities from 2 kg upwards per unit.

Feed bagged goods in the process

Feed bagged goods in the process

Feed large quantities of bagged goods in to the process

There are many processes in which bulk products need to be introduced in large quantities from sacks and bags. For example, in to a mixer or stirred tank, this is often the case in the food or chemical industries.

RNT 180 with lumpbreaker and conveyor belt

The sacks are loaded on to the conveyor belt which transports these to the loading station activated by a foot switch, where the sacks are then opened and emptied. A waste chute makes it possible to dispose of the empty bags laterally into a waste bag compactor.

To help reduce the dust inside while loading there is the option to either connect the product loading station up to a local extraction system or to have a dedicated vacuum conveyor for dust removal.

lump breaker

If the product tends to form lumps during storage, a lump breaker can be connected under the feed hopper. This crushes lumps up to about fist-sized lumps.

Conveying and dosing in the food sector

Conveying and dosing in the food sector

Conveying and dosing of powders and solids in the food sector

In regards to bulk goods the food industry is very interesting because hardly any other sector can offer such a variety of different powders, granules and bulk or piece goods.

A wide variety of handling tasks for example the finest powders, corn starch, spices, mushrooms and even bacon cubes. In terms of process technology, the methods for transport and dosing are as diverse as the products themselves.

Purely mechanical conveyor systems often reach their limits, be it for hygienic reasons or for explosion protection reasons. A simple screw conveyor, for example, conveys product, but it never gets completely empty and is difficult to clean.

At the same time,  granulated sugar, for example, places so much stress on the mechanical system that powdered sugar is produced, which in turn has a very low minimum ignition energy (MIE), which increases the risk of explosion. Vanillin powder tends to form lumps in dosing screws, which can undoubtedly disrupt the subsequent mixing process. Vacuum conveyors in combination with vibratory feeders can elegantly solve these problems.

Metal powder handling

Alu+Edelstahl Pulver

The correct handling of powders within the additive manufacturing industry

Whether it is metals or plastics there are numerous different powder handling tasks to be solved within the Additive Manufacturing (AM) industry.

However, for various reasons, metal powders represent a greater challenge for powder handling. This involves the powder supply to the 3D printers the recovery of unbound material and its reclassification and recovery (recycling) for reuse.

With the Volkmann PowTReX, the combination of the process steps of vacuum conveying, controlled sieve dosing and ultrasonic screening represents a compact platform to solve these demanding tasks.

Printer and PowTReX

In connection with the correct container and container handling, safe, sealed and – if necessary – inert powder handling can be achieved. This means that not only stainless steel powders, also aluminum and other sensitive metal powders, for example, can be safely handled.

Volkmann on the high seas

Applications for the transport of powders and bulk materials with vacuum conveyors can be found not only in all known industries, but also in other locations around the world. The conveying often takes place inside buildings and production rooms, but Volkmann vacuum conveyors also work perfectly outside as well.

In addition to filling silos and conveying animal feed additives on fish farms, vacuum conveyors can even be found on ships which are used offshore for the generation of energy. Powdery additives are required during operation and these are delivered in bags which must therefore be emptied and then conveyed by vacuum.

Just in case – UHU!

Just in case – UHU!

There is probably hardly anyone who has never used a UHU product. The glue in the black and yellow tube has become one of the best-known brand products of our time. UHU develops and produces high-quality adhesives for children and parents, but also for do-it- yourselfers and professional applications in trades and industry. The development of ever better and safer products with an eye on future generations is a challenge and commitment in one.

Cleanliness and safety

Most the products are manufactured in the industrial premises in Germany, located right at the centre of the small town of Bühl at the foot of the Black Forest. Cleanliness and safety are hence matter of course in the production. The creation of adhesives generally calls for a variety of solids and solvents, which are combined in a mixer or batching tank. To further increase the cleanliness and safety, UHU decided to use Volkmann GmbH's INEX vacuum conveyors in 2007, and hence in favour of a sealed introduction of solids to the mixer.

What were the decisive reasons for using the INEX systems?

Volkmann had already opted for an ATEX certification of their vacuum conveyors in keeping with Directive 94/4/EC in early 2002, which generally permits them to be employed in potentially explosive, dusty atmospheres. Where potentially explosive gas atmospheres are concerned, standard vacuum conveyors are turned into a type- tested INEX system by an additional inertization using protective gas (nitrogen). This allows the safe and dust-free introduction of solids into containers that are pre-filled with solvents (zone 0). One essential element of the certified INEX vacuum conveyor system for this is the purely pneumatic control, which guarantees the reliability of the process by means of various safety queries such as "enough nitrogen provided for inertization", for example. In addition, this INEX control unit can be directly installed in zone 1 or also be used in a mobile fashion on a driving carriage. Besides the safe introduction, this conveyance process also offers the additional advantage that dust and gas emissions are avoided, thus protecting the health of the workforce and ensuring that the production stays clean.

Process safety thanks to vapour barrier

Rising vapours and fumes can cause problems when mixers are filled, and are able to reduce the safety of the process. The shut-off flaps installed to separate the INEX vacuum conveyor from the mixer for introducing the solids into the process can be moistened by these rising vapours and fumes, leading to thick deposits of the solids and their getting stuck. Another frequent consequence is also that the filter inside the vacuum conveyor is moistened and becomes blocked. But the shut-off flap of the INEX system could be kept dry successfully by means of a nitrogen-operated vapour barrier which ensures uninterrupted and reliable operation.

Various installation situations on site

In grown production facilities, one will find highly varied installation situations where standard systems are often unusable. Height restrictions, oblique filler pipes and already provided system components often leave little room for new plant technologies. But given the fact that the entire engineering is performed by Volkmann in-house, and thanks to the high degree of self-production, the INEX vacuum conveyors could be successfully adapted to the various local installation situations of the mixers while also providing adequate access for operability and maintenance.

There can be many reasons for using Volkmann vacuum conveyor systems, as the UHU example illustrates. But one of the most important ones is certainly the close and partnership-based cooperation without which these various customized solutions would hardly be possible.
