" We have been using Minds products for many years and their automation software equips now five of our six plants. We even specified them to provide the control system on the latest two Astec plants we acquired. They are very responsive and have easily incorporated our requests in their products. I would recommend them to anyone who wants a fine control of their production process. "

BatchTronic Highlights

Multiple Console Options

With the number of screens ranging from one to four and a 'zero console' option, the BatchTronic fits all types of asphalt plants and budgets.

The system has the capacity to control all asphalt plant operations or just the tower. An industrial grade computer with security and redundancy features ensures reliable operation in all situations.

BatchTronic runs on Microsoft Windows® via a communication driver, RTX from IntervalZero, and uses one or more unique I/O boards, depending on the plant complexity, over a real-time TCP/IP protocol.

Clearly See Your Operations

The human interface has been conceived with ergonomics in mind. The exact 3D representation of the actual asphalt plant reduces the learning curve needed to use the system.

The operator can actually link what is seen to the actual physical mechanisms. Large arrays of numbers are avoided in favor of clear symbolic information.

The operator is always in control of the process which can be stopped and resumed anytime while direct control of motors is always possible.

Ultimate Real-time Control

Timing is of the essence of batching processes. BatchTronic provides tools to understand and customize how actions are scheduled. The result is a clear understanding of what precedes and what follows any given event. Many options are available to fine tune the process in order to maximize asphalt plant flow rate and accuracy. In many real-life cases, these options have proven to be instrumental in dramatically improving the asphalt plants maximum tons per hour output. 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 DrumTronic product page for more information on drum 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.

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.
