Automatic Replenishment Of Aggregate Bins
OverviewThe MPAQ Material Handler is the perfect addition to a busy concrete plant. A programmable logic controller inside the panel keeps your aggregate bins full and is designed for unattended operation.
The integrated manual backup is implemented with plain switches and no electronic components, guaranteeing that you can always operate the plant. An optional remote operation module with web-based software allows you to operate the material handler panel from anywhere within your company network using a simple Internet browser.
Using simple selector switches in the overhead bins you can assign which ground hopper supplies material to each bin. The high bin indicators in the overhead bins start the filling sequence. The system automatically closes the ground hopper’s gates and purges the belts after the high bin indicator is covered again with material.
To increase overall speed, if another bin calls for material while replenishing the first bin, the next delivery starts only a few seconds after the first bin is full. Belts don’t have to empty completely. A preset “material gap” on the belt allows the turnspout to relocate to the next bin just in time to deliver the next material coming up the belt.
Sophisticated logic allows you to set one of the bins as a high priority, while the other bins operate in a “first come first serve” mode. Flow switches are programmed to trigger alarms in case the material or the machinery stops for any reason.
Automating your material handling system is an economical way to increase your plant production capacity.
