This month DHE Inc. completed an aggregate bin replacement and material feed system upgrade in Saint Helena, California.  After 73 years of service, the multi-lined and patched 140 Ton NOBLE Aggregate Bin needed to be replaced.

In addition to a upsized 12 yard Aggregate Weigh Batcher, the 134 ton CON-E-CO Aggregate bin features 6 compartments fed by a Remote Control 30” x 500 TPH Radial Stacking Conveyor.  The loader operator simply indexes the radial stacker by pressing 1-6 on the remote.  A NOBLE galvanized 30” x 48’-0” jumper feed conveyor was added to feed the radial conveyor from the existing below grade loader hopper.

In 1999 the cement section was upgraded with a CONECO Gravity 765 BBL Silo, 12 yard Cement Weigh Batcher, 30” Batch Transfer Conveyor and PJ980 Mixer Truck Dust Collector.  The two original NOBLE 700 BBL Cement Silo’s remain apart of the plant and provide fly ash and slag storage.
