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.

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.

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.
