Besides pure material transfer, additional requirements can be placed on a vacuum conveying system. For example, a given batch weight is to be fed to a mixer or reactor or perhaps the material should not be delivered in one go but over a longer period of time as a constant material flow to aid mixing. So, sometimes, a combination of weighing and constant material delivery (dosing) is required.
These requirements can be met by a combined transfer and weighing conveyor (CONWEIGH) or by a dosing system placed at the product outlet of the vacuum conveyor.
Some processes require a continuous feed of a powder, granulate or other bulk material over a longer period of time. This may be a requirement for feeding a mixer or reactor, for example, where a bulk material is to be mixed into another product (or liquid).
With a dosing system, bulk material from a feed pipe, a storage container or other mass flow device is delivered to the downstream process evenly and with a predefined quantity over time. In this way, continuous product delivery can be achieved with a vacuum conveying system that operates in cycles.
Our product portfolio includes the following dosing systems:
