A conveyor system with extraction technology is suitable for fully-automatic chip transport from several processing machines to a central collection point. Room air serves as the carrier medium. It can transport dry or slightly damp chips across a distance of up to 560 m. With the use of modern fans and control technology, the system requires little energy. It is also space-saving and offers great flexibility for the setup or conversion of the machine park.

Areas of application

The vacuum conveyor system serves to transport chips fully automatically from several processing machines to a central collecting point. The carrier medium is room air, which transports the dry or slightly damp chips over a conveying distance of up to 560 m. The system is used in production areas with a large number of machines (wet and dry processing).

Properties

Central extraction systems

The central extraction system is the heart of a vacuum conveying system. It generates the vacuum. It also separates the chips from the suction air and cleans the air subsequently.

Reverse flow systems

Reverse flow systems for extraction technology convey metal chips from processing machines or collection points to the central extraction system completely automatically. Room air serves as carrier medium, which transports the dry or slightly damp chips across a distance of up to 500 m. Depending on the requirements, the extraction stations are integrated in the machines or provided underneath the chip conveyor.
