Position: This alliance allows Scale-Tron to give turnkey service with fast turnaround when required. Our CAD system creates 3-D models that can be viewed on your own computer from any angle as well as 2-D pictures of the new aggregate batching equipment superimposed on photographs of the original plant.In conjunction with J. McCoy Equipment and Ocmer, Scale-Tron offers custom concrete batching plant and control system design and fabrication.
In 2005, a Canadian precast company was building a new facility and required a concrete production plant. The contract was awarded to McCoy Equipment Ltd. for the mechanical equipment and structure, and Scale-Tron Inc. for controls. A twin shaft mixer delivers 2.2 cu. m. wet cast concrete (2.9 yd) into a 3 yd bucket for a total capacity of up to 116 cu. yd. per hour.
View shows aggregate batching bins being placed on the support structure. Aggregate scale and mixer feed belt are seen underneath.
The three aggregate batching bins are refilled from an above-ground receiving hopper and inclined conveyor to a reversing shuttling conveyor. Cement silos feed a cement scale over the mixer via screw conveyors. Water and admixtures are by volumetric controller.
Cement silos are in position here. These silos were subsequently fitted with Scale-Tron’s SiloWeigh.Net silo weight batching system. Strain gauges attached to the silo legs measure the compressive force and the resulting weight values are displayed on an internet browser screen on any computer on the plant’s local network system. In addition, all readings are transmitted to Scale-Tron’s SiloWeigh.Net central database, where historical data and trend graphs are available. This in turn is connected to the cement company’s ordering /dispatching database, creating automatic orders when each silo reaches a predetermined refill level.

Most of the plant components are in place
Here, most of the plant components are in place. The twin shaft mixer can be seen at left (colored green). The upper level construction in the middle of the picture became the control room. This whole section, including the bins, was walled in.
batching controllers are Scale-Tron’s BatchTron II, with Demand Station at ground level. The demand station incorporates a second, smaller touch screen that accepts formulas and Batching sizes to be made, allows batches to be ordered and corrects water amounts. Sand moisture is corrected by Scale-Tron RadarTron microwave moisture sensor.
Completed plant shown below.
This low profile Batching plant was designed to produce wet cast via a twin shaft mixer at left and dry cast via a planetary mixer at right. Each has its own cement scale and aggregates are weighed by the bidirectional conveyor scale at center. Aggregates are raised to each mixer by skip hoists (shown in lowered position). Batching plant is shown superimposed on existing building (transparent gray).

This is an initial design for a high capacity precast / wet cast production Batching plant; a conveyor scale feeds the twin shaft mixer via pocket belt and holding hopper. aggregate batching bins are recharged via twin pocket belts and flop gates to keep the whole plant within a very small footprint. The 7.5 cu. m. mixer discharges into Tuckerbilt trucks via Ocmix's reduced discharge door and chute to reduce the overall height of the mixer platform.
"Artist's impression" of what plant will look like when installed. Batching plant drawing has been superimposed on real life photograph of precast plant in background. Note the compact footprint of this design which is capable of 290 cu. yd. per hour compacted concrete.
With two Ocmix RG7500 twin shaft mixers delivering 6.6 yd. per Batching, this plant can deliver up to 520 yd. per hour into a combination of trucks from each side plus a traveling weigh hopper running under either one or both mixers.
