With automation replacing manual work in more and more fields, vacuum conveying is becoming one of the best options within its respective industry. Boasting safer and more efficient transportation of materials, the system is providing a clear path forward – one we’ll break down in this article.
Features

Vacuum conveyors distinguish themselves from other pneumatic models through their use of pressurised air. While many other models use air to propel material through pipes, vacuum conveyors use negative pressure to draw material towards the desired area – think of a vacuum cleaner collecting sand off the floor.

When installing a vacuum conveyor, you will find customisation and installation to be easier than expected. The systems can be adjusted (pipe length, motor strength, etc.) to suit your needs, depending on the materials you’re likely to process. Plenty of online services, such as https://www.aptech.uk.com/pneumatic-conveying-systems/vacuum-conveying, will advise you on the best options before installation.

Most models are inherently self-cleaning thanks to the airflow, and low-maintenance thanks to the design, with check-ups being recommended but by no means required to ensure smooth operation. For a simple video explanation of the vacuum conveyor’s processes, see here.

Pros and Cons

There’s a reason why vacuum conveyors are becoming increasingly popular with the host of benefits they provide over their counterparts.

The aforementioned self-cleaning and customisation allow for smooth integration and maintenance, but vacuum conveyors also provide a measure of safety to the material and the operators. The hermetic (airtight) design means contaminants are highly unlikely to get in, and toxic substances are highly unlikely to get out and harm workers.

Materials usually don’t need sorting or separating beforehand. The vacuum conveyor can separate solid material within the process and performs exceptionally well with powdered material.

The drawbacks are mostly manageable, provided you are properly prepared. For example, you may struggle with processing large amounts of material, and it may require a lot of energy to power. Luckily, the machine is highly efficient with its energy use, and you can minimise the risk of blockages by gradually adding material and ensuring it is suitable for the machine.
