Pneumatic & Mechanical Conveying

Pneumatic Conveying

Every lean phase pneumatic conveying system that we build and supply is individually designed in house. The main reason for this is that every requirement from or customers is different and conveying rate requirements will differ depending on the material being conveyed. Therefore an individual approach is vital.

While we would always prefer to provide a complete powder handling system - effectively a turn-key project - this isn’t necessarily what our customers need. Quite often, a customer will need a production line to work more efficiently. This isn’t just a simple case of increasing the size of the air compressor and hoping for the best. It involves a very clear understanding of the customer’s needs and an equally clear understanding of the way that a powdered material flows when it is being conveyed. This is something that we are very good at and we have successfully modified many powder handling systems over the years.

Lean Phase Conveying

With pneumatic conveying, our preferred method is Lean Phase conveying where a product is conveyed within a vacuum or literally blown along a conveying line. The air speed, which is calculated on a metre per second basis and the diameter of the conveying pipe will determine the amount of product that can be conveyed per hour. Lean phase conveying is ideal for most conveying purposes from large scale bulk material handling through to the handling of small amounts of a minor ingredient. Lean phase conveying is also ideal for handling organic powders that may carry the risk of explosion. In this case, the entire system will be designed to the latest ATEX regulations.

Dense Phase Conveying

The other type of pneumatic conveying is Dense Phase Conveying. Dense phase conveying is the system that we use to handle fragile products such as breakfast cereals, some animal feeds and nuts. With dense phase conveying a slow moving ‘slug’ of product is gently pushed along the conveying line. As the slug moves along only the product that has contact with the inside of the conveying line will be damaged. Product that does not have contact will be delivered to the next part of the process in perfect condition.

Mechanical Conveying

We have vast experience with mechanical conveying systems with both full turn-key provision and with individual components. Where a very large quantity of material needs to be conveyed a long distance, mechanical conveying is the only economic option. A complete mechanical system will consist of mixers, vibratory tray feeders, screw conveyors, belt conveyors, bucket elevators and possibly a mechanical silo discharge unit.
