Batch material transfer control seems an easy task to carry out, but the reality is that many functions are necessary if the system is to accomplish accurate batch material transfer control. Weighing systems with device-level controls can help.
Fine powders often need air injection to increase flow rates to an acceptable level. With entrained or injected air, powders flow like water, but when deaerated, the extremely low flow rate may be confused with a hang-up or arching condition.
As the pharmaceutical industry has matured, concerns about the safe handling of drug compounds during the manufacturing process have increased. To meet exposure limits and protect batches from any kind of contamination, the industrys need for improved containment has increased.
Buildup is a potential danger in horizontal pneumatic conveying systems, particularly when velocity is reduced. This exclusive contribution from the Particulate Solids Research Institute addresses this issue.
Plant engineers who find it is difficult to get good level measurements have plenty of company. A recent poll shows that it is considered to be one of the two most vexing problems by process automation professionals.
Pneumatic conveying has long been a popular choice for moving bulk materials. However, the technology hasn't been standing still, and this can influence the choice between several types of pneumatic systems.
Improper startup can result in excessive temperature and radial loading, both of which can lead to lower pump reliability from problems such as seal and bearing failure. Consultant Ross Mackay describes the three steps that should be followed during pump startup.
Like the 20th Century’s Great Conflict, the first Fieldbus War never really ended. But what will the outcome be this time? This article from CONTROL makes an educated prediction on how the battle may turn out.
