" At DJL, we have been using Minds control systems with satisfaction for more than ten years and we currently operate 15 plants with those systems, plus 2 ordered this year. We use them on batches, drums and hybrid plants. The performance is there and the service is very satisfactory. I can recommend them without hesitation. "

DrumTronic Highlights

State of the art

Dependable, accurate, reliable, and customizable. DrumTronic is ideal for a simple bitumen and aggregates blending-only application, or comprehensive total plant control. Its software adaptability is paired with a modular hardware design made of one or many of the same electronic I/Os board. It comes with an industrial grade PC, security and redundancy, remote access and support. It is complemented with Android and Apple apps and a beautiful graphic signature. Did we say it is very reliable? It is Drumtronic and it gives you the control and the peace of mind.

DrumTronic software

Clearly See Your Operations

The human interface has been thoroughly designed in collaboration with actual operators. The layout of information allows for a quick understanding of the overall workings. Delays and timing, for example, are displayed over a graphic representation of material flow and plant layout. These types of details help to prevent errors and misinterpretation. Large arrays of numbers are avoided, in favor of clear symbolic information.

Always In Control

The operator remains in control and the process can be stopped and resumed anytime while direct control of motors is always possible. The software can control silo storage, including complex conveying layouts, ensuring a clean and precise change of silo following a mix change. For combo or hybrid asphalt plants requiring management of towers, individual batches, and large drum mixes, MINDS has solutions to visualize your operation for ultimate control. See the BatchTronic product page for more information on batch plant control. Our automation software can also be linked to Tessera Single Site (and Tessera Enterprise, coming soon) so managers can see a high level overview of totals, consumption and inventory usage.

  • System is easily customized through multi-level user accessible parameters

XIO Controller
Dedicated hardware for inputs & outputs

All the electrical inputs and outputs of our plant control systems are handled through one or many instances of a single type of electronic board: The XIO. A small batch plant requires just a single one while a very large drum plant may require upwards of 5 boards. Employing one type of I/O board means there is just one model to manufacture, stock, maintain and support. We have deployed 1000s of them at 100s of plants on 4 continents.
