Although it is quite unnecessary for users of conveying systems to be familiar with all the technical aspects, it is helpful to understand the basics of how these systems work. There are, however, certain factors that manufacturers will have to be made aware of so that they are able to design a conveying system that meets all the customer’s needs.
According to Hydraulics and Pneumatics, the future for pneumatic systems looks bright.
Bulk Density of Materials
Material bulk density is important, since it determines the size of certain system components, including air sources and vacuum receivers. Designers need to work out how many cubic feet of air per minute are needed for movement of the material. The heavier the materials, the more power will be needed to move them, whilst lighter materials are easier to move. The exception would be for very fine powders that have challenges of their own.
Characteristics of Materials
For vacuum conveying systems to be efficient, it is necessary that designers understand how the materials will behave in different conditions. Whether the material is free-flowing or not is a key consideration. The less free flowing it is, the more modifications are likely to be needed to equipment.
Distance Material Needs To Be Conveyed
How far the material needs to travel is another important factor in the components and design of conveying systems. The further the distance, the larger the vacuum pump needs to be to produce sufficient airflow to push or pull it through. In pneumatic conveying, calculations for moving materials vertically and horizontally are both carried out in linear feet. If you need clarification on this, a company such as https://www.aptech.uk.com/pneumatic-conveying-systems/vacuum-conveying/ will be able to explain the details.
Rate of Conveying
Another factor to take into consideration is the rate that material is moved through the system. The process may be continuous or may be a batching operation. This can make a difference to the size of the system, and a more powerful vacuum source may be required.
Types of Container
The type of container that the material is in will dictate what type of pick-up point is needed. This needs to be customised to suit the specific process.
Different equipment is needed for different materials and processes, so you need to be aware of this.
