Mixer Control System Upgrade

User Requirement

Global engineering group Sandvik were looking for a company with control system knowledge to upgrade one of their 21ZEMX mixers based at their Coventry site. As this is an area where we as a company excel, we were happy to take on this project.

With two out of the three mixers on site already up to the required standard, there were various elements of the upgrade that were key.

Sandvik required we focus on monitoring the product and temperatures, adding the ability to log key data collected. This information would allow them to control the mix performance.

The Solution

Having previously supplied Sandvik with the control panels for their other two 21ZEMX mixers, our engineers were able to build an identical control panel to fit with their needs.

Previously the mixer used a manual control system and push button to control the process. We replaced this with a new HMI and automated system.

For accurate monitoring of the product and mixer temperature we installed new analogue sensors, these feed back to the PLC in the control panel.

Data collected can then be transferred to the specialist Aquilla software we installed on the mixer PC to log data collected.

The Results

With the recent upgrade of the final 21ZEMX mixer at our Coventry branch, our factory now boasts a trio of mixers equipped with cutting-edge, advanced control systems. This significant improvement empowers us to enhance both the quality and quantity of our end product. The system upgrade has also resulted in a more user-friendly interface, simplifying operations and ensuring a seamless production process. On top of that, we have implemented an alarm system on the HMI that promptly alerts operators to any potential faults, enabling us to swiftly address any issues that may arise. By incorporating this additional feature, we are enhancing our ability to react swiftly and effectively in the event of an error, ultimately improving our overall efficiency and productivity.
