The professional handling of dusts and powdery solids requires a comprehensive consideration of the task. In addition to the purely technical questions relating to feasibility and implementation, numerous boundary conditions must be taken into account.

One of them is the possible use in potentially explosive areas. The crux here is that these areas can not only be predefined from the outside, but potentially only arise through the actual conveying task or the conveyed goods themselves.

This is due to the fact that every substance which is flammable, in either a powdery or dusty form with fine particulates of less than 500 µm, also has the capability for a dust explosion.

Conventional, mechanical conveyor systems often reach their limits of use. Pneumatic vacuum conveying systems, on the other hand, can be designed without ignition sources and are therefore particularly suitable for such purposes. Both for organic compounds and for inorganic substances such as metal powders.

As an extract from the “ATEX, Explosion Protection and Powder Handling” seminars that take place several times a year, this short video gives an initial insight into this extremely complex topic.

Handling of larger amounts of Metal Powders in the aerospace industries

With the modular design of the Volkmann Vacuum Conveyors and Sieves they can be easily adapted to larger transfer rates, required either by a Multi-Machine layout with centralized powder handling or driven by substantially bigger printers.

The following article from Launcher USA and AMCM GmbH (an EOS Group company) highlights the use of Vacuum Conveyors, PowTReX sieving and powder recovery stations in such a case.

Vacuum conveyor with lifting and swiveling columns |

In many industries it is still common practice to fill filling systems, presses or containers by hand from above.

This process is usually unergonomic for employees and rather time-consuming. This procedure often harbors undreamt-of dangers, for example that of a dust explosion.

An alternative to automated filling are lifting and swiveling columns that are equipped with a vacuum conveyor for material transfer. The vacuum conveyor sits in a holding fork that is mounted on the lifting column and can be steplessly raised and lowered.

This is how bread crumbs are brought to the fish

This is how bread crumbs are brought to the fish

Big bag emptying and conveying of bread crumbs |

Bread crumbs are often used in the production of fish fingers and other fish dishes. The task was to empty the big bags filled with breadcrumbs and then to feed the breadcrumbs to the machines for further processing.

This is how bread crumbs comes on the fish

A cost-effective solution was sought in order to empty the big bags and continue to use the existing crane. The customer then preferred to use mini hoppers as emptying aids. These have a small overall height, are easy to handle and cleaning when changing products is easy.
Big bag emptying and conveyance of breadcrumbs

The big bags are emptied and transported to the machines by four VS 250 vacuum conveyors. 12 tons of breadcrumbs are conveyed and processed every day.

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.

Weighing and dosing bulk products

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

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.
