The system batches up to three cements, four aggregates, six admixtures, and water. It automatically controls three cement aerators, a cement hopper vibrator, and aggregate hopper vibrator, and an aggregate conveyor. Names can be stored for each material in the plant, active bins and bottles can be assigned a material name, and approximately 300 mix formulas can be stored in its memory. This information can be copied to an audio cassette tape for backup. The system keeps track of how much material is in the active bins and bottles and will notify the operator if the required amount of each material is not available. The system also features instantly adjustable ribbon feed control of cement and aggregate discharge into the truck, batch time trimming of water and admixtures, automatic freefall calculation on weighing, split weigh/feed cycles for large batches, compensation for moisture in aggregates, discharge sequencing, returned concrete, inventory recording, and automatic ticket printing with batch information for each truck.
