Expanding into a new market, anticipating future environmental requirements, and meeting customers near and long term mix design demands was the basic building blocks for the new Holliday Ready Mix Bakersfield California Concrete Batch Plant facility.

As material delivery costs continue to rise and markets get more competitive, the versatility of the plant would be critical for Holliday Rock to be a major producer in the growing commercial and residential markets.  Automation would be key for the entire facility to be operated by one operator.  The flexibility of the delivery truck schedules would be critical to the “Lean Concrete Production” design of the new operation.  Aggregate Materials can be delivered 24 hours a day if required, with separate automation for the driver.  Cement Bulk Truck drivers have an off-loading station to include individual silo level lighting and controls.

With their aggregate pit located approximately 50 miles away, Holliday wanted to take advantage of after hour material haul rates.  The NOBLE 800 Ton Bunker material handling system allows driver to deliver after business hours, and has room for future expansion from 4 to 8 different materials.

The CON-E-CO BatchMaster Concrete Batch Plant has a throughput capacity of 220 yard per hour and is all about producing a tight spec product at an aggressive throughput rate.  The 36” X 1,050 TPH Batch Transfer Conveyor, Water Weigh Batcher, mixer truck surge hopper and drive through alley are just a few key features to the plant.

Facility environmental design.  The future has arrived for California Ready Mix producers.  The Holliday plant foot print for the “process water zone”, needed to be compact enough in order to allow the plant manager to stay ahead of the sites water management responsibilities.  The process water zone includes the Concrete Batch Plant, Mixer truck load out, Cement offloading, Mixer truck slump racks and return truck wash-down area.   By locating the Mixer truck wash out between the CON-E-CO batch plant and material bunkers, Holliday was able to reduce the amount of supervision to stay ahead of their process water requirements.  Any water outside of the “Process Water Zone” can remain as Storm water, and has different permit requirements.  With the entire yard paved and the concrete drive way perimeter raised around the batch plant area, the two waters remain separated and manageable.  Water is recycled into fresh concrete where-ever possible.  Mixer Truck washout is also a closed loop process.
