LTC - ISS Plant

The Lang Tool Co. ISS Plant consists of a mix truck with a computerized scale system, a piston grout pump and either one or two 35 ton silos with scales, depending on job specific conditions. The plant produces slurry on a continuous basis. The plant operator enters the total weight of cement to be delivered to a mixing cell and sets the rate of delivery, in lbs/minute, and the water ratio. The rate of delivery can be adjusted at any time to match the mixing progress of the blender. The water ratio can be changed as well if site conditions vary. When the entered quantity of cement is reached the system shuts off the delivery, which prevents any inadvertent overdosing. Lang Tool Co. frequently averages over 125 tons of cement a day on ISS projects.
