Pneumatic conveying system
Customer needs
A customer approached PAM in need of conveying powder from two silos to a central process plant. The choice of which silo the material is to be transported from should be able to be made automatically via the customer’s control system.
The solution
PAM’s engineers developed on the basis of data on the nature of the material and the distance between the silos and the extraction site, a solution where a blower with suction through a pipe line, conveys the material approx. 150 meters horizontally and 25 meters vertically. Collection of the material takes place via two pieces of PAM air-locks type UL, which pressurelessly dispense the material from the silos into the air flow. The material is carried on to a filter cyclone, which separates air and material efficiently. The material falls to the bottom of the filter cyclone and the air disappears out through the filters. The material is then pressurelessly led out of the filter cyclone through another PAM air-lock type UL, and dosed directly into a mixing process in the customer’s existing plant.
In other cases, the pneumatic conveying system could also be designed as a pressure system. In this case, the blower would be located before the silo outlets, and in this way the material from the collection points would be carried by pressure instead of suction. Since, for natural reasons, there will always be minimal leaks through the air-lock, a suction system can in many cases be preferable, as this ensures any leakage air disappears into the pipe line, rather than moving back into the system before the collection points.
Pneumatic pipe conveying is used in many industries as it is an energy efficient way of conveying powder and granules. At the same time, the risk of metal and other impurities in the material being transported is avoided, and pneumatic transport is therefore particularly suitable in the food industry or chemical industry. In contrast to the use of mechanical transport, the use of pneumatic transport significantly minimizes the number of moving parts, thus minimizing the need for maintenance and increasing the uptime of the plant.
We (Stiesdal SkyClean) can highly recommend a cooperation with PAM, also when technical limitations must be challenged.
On our way through the project, we found PAM’s great innovative power and flexible design department particularly useful, where technical solutions changed with PAM’s intervention.
The challenges we had initially on our project have been made significantly easier because of the cooperation with PAM.
PAM works relentless to ensure their delivered product meets all the criteria required and to ensure the quality is seamless. They are joy to work with.
The PAM solutions most noticeable difference for our operation is how it has improved the efficiency with our storing and loading systems, and ultimately how this has added cost saving benefits to our meal handling operations.
I selected PAM because of their dynamic, professional approach and fine attention to detail. This was further supported with their ability to adapt and provide me with a fantastic solution, for both storing and transporting meal.
PAM helped us designing a new product suitable for our production and the collaboration was excellent all way through, PAM is a very flexible and competent partner to work with.
PAM is good at communicating – they revert quickly on inquiries and this way the dialogue easily becomes very close.
