RNA equipment is synonymous with quality and reliability and strives to maintain its reputation in the field.Often equipment supplied is ran on a 24/7 basis leaving little time for preventative maintenance, below are a few suggestions to help maintain peak performance.
If possible try to inspect the equipment prior to the start up of a production run, if the equipment has been recently purchased always read the manual before operating the machine. Check the utility services (voltage, compressed air, and electrical equipment) before running the equipment often ancillaries such as sufficient air supply are overlooked.
In the case of a bowl feeder the internal lining should be clean and free of dust and the surrounding area clear.
If possible, have a checklist available; be sure that each operator is familiar with the operating instructions supplied. RNA supply clear instructions with each feed system with pre set parameters documented as a quick reference guide.
OEM spare parts are available of the shelf but for unforeseen problems try and carry minimum spares and be aware of the fitting procedure. If a problem occurs off the shelf spare parts allow you to schedule a replacement at the most convenient time.
TIPS FROM THE TECHNICAL DIRECTOR RNA Technical Director, Mick Keane , gives his advice on protecting and maintenance of bowl feeding systems.
Regularly clean the machine
“Machine cleaning is often a standard requirement in the pharmaceutical and food industries. In fact, all feeding systems will benefit from regular cleaning to improve the reliability and life-span. Debris and dust on the component tracks will greatly decrease the performance of the feeder; in this case, cleaning a feeder is essential at the start of a production run”.
“RNA can provide simple dust covers or even full acoustic covers to protect the equipment.”
“Check the bowl top is tightened down correctly and that the area surrounding the feeder is clean and tidy any cables should be fastened securely and away from edges of the machine.”
“Spring packs and coils should be periodically checked, cracked or rusted spring packs should be replaced immediately .Coils should be set at the correct factory tolerances as set out in the manual.
RNA dive units are low amplitude and as a result have low noise characteristics any increase in noise levels should be investigated immediately.”
Training is recommended
“Most special purpose machines perform in different ways. RNA continues to develop each system’s performance to meet customer’s requirements, although it is beneficial if operators have received training. Training helps the operator achieve maximum machine performance and take ownership of the equipment. To meet production goals and maximize equipment investment, I advise operators to be involved at the beginning of the project even at the concept of the system.”
Set up an in-house maintenance plan
“Scheduling a maintenance plan focuses on setting up core maintenance tasks and ensures the machines performance. A maintenance plan can include routine inspection, testing and performance trials and cost analysis.”
“Setting up a maintenance plan is a cost-effective way to maintain peak performance of equipment.”
