What is a permanent central vacuum?

Mo explains the characteristics and advantages of a permanent central vacuum
For large productions with numerous material loaders and consequently many delivery points, large throughputs, frequent conveying cycles, and long conveying distances, there are two solutions for automated material supply: Single lines (line vacuum) or a central permanent vacuum system (central vacuum). …

Which processes are important for material conveying?

mo explains: what is important to consider for time or sensor conveying
The principle of suction conveying relies on the vacuum pump generating a vacuum that is great enough to range through the material feed lines and the material loaders to the material feed. …

How do the various vacuum generators differ?

Mo briefly presents the most commonly used vacuum generators in the plastics industry

Part of the heavy workers of pneumatic suction conveying – the precise term for the most important conveying method in plastic processing – are without a doubt the vacuum generators. …

How can abrasion be minimized for vacuum conveying systems?

Mo explains abrasion and measures to prevent abrasion

The distances the material travels in the pipe lines from the material supply to the processing machines can be gruelling – both for the material as well as the material lines. …

When is it necessary to purge material lines?

Mo explains why purging can contribute to plant safety.

The point of purging is to remove or minimise transported material deposits from a material line. When the vacuum of vacuum conveying systems shuts off after the conveying cycle, any remaining material in the line remains in the line and ideally is transported again during the next conveying cycle. …
