Pneumatic conveyors are designed to convey dry materials. It is an enclosed system that consists of tubes or pipes from which the material will flow to its destination. The system works on the principle of pressure difference. By lowering or increasing the pressure in the system, the difference in pressure is achieved. Pneumatic conveyors are made up of fewer components and accessories as compared to other conveying systems. Materials like wheat, sugar, cement powder and other dry materials are conveyed through this system.
The choice of having a pressure or vacuum pneumatic conveying system is completely situational. The engineer is responsible for choosing either one. The choice will depend upon the kind of material that one wants to convey. Also, the availability of resources to perform the task will matter.
Let’s dig up and see that what is kept as an advantage in both types of systems.
Reason for choosing Vacuum conveying system
- Dust-free transfer: As the leakage is inward, therefore there is no scope of spillage outside. Therefore we can say that it is a dust-free transfer.
- Easy to clean: It is easy to clean and does not require many tools to do so.
- Efficient: We all look for this factor for any type of machine/ system. We cannot doubt the efficiency of vacuum conveyors but yes pressure conveyors are any time more efficient. However, the amount of pressure one will need to use will be directly proportional to the cost. Hence, look for all the criteria and then choose either.
Reason for choosing pressure conveying system
- Distant conveyance: Vacuum conveying system has a limitation when it comes to distance. There are incidents when conveying through a vacuum system becomes highly expensive leaving the engineers to choose a pressure pneumatic conveying system. At times it is better to push the material forward than to pull it towards the outlets. Therefore, in such a situation, a pressure conveying system is a preference.
- Avoid contamination: Vacuum conveying system fill air inward hence, the chances of contamination will increase. There are high chances that a foreign particle or unfiltered air droplets will enter the system leading to risk or contamination. However, this is not something that is a requirement every time. But, at times, the engineers may need to consider it.
The industry owners must know the possible advantages and disadvantages of the conveying system they choose. For every system, you will have to bear with its limitations also. We would suggest buyers to come over for a discussion before choosing any of the systems.
