From hauling dirt to processing it, excavating contractor J. Lee Milligan has invested in a new CDE EvoWash sand washing plant that is expected to more than quadruple processing volumes at the firm’s production facility in Amarillo, Texas.
Founded in 1937 with a single truck and a contract to haul dirt for $1.25 per hour on New Mexico’s Conchas Dam project, J. Lee Milligan has grown to become one of the largest heavy highway construction firms operating in the panhandle and South Plains of Texas today.
Its latest investment, a first with washing experts CDE, will lead to the commissioning of a new 200tph dual pass EvoWash this summer. The plant will replace an existing 40tph traditional sand screw.
Chris Brannon, Aggregates Superintendent at J. Lee Milligan, said: “We’re losing quite a lot of material to the pond, meaning we’re having to work harder for longer to meet our production targets.
ACCELERATING RETURN ON INVESTMENT
Ronan Duffy, our Business Development Manager, added: “Though sand resources in the Texas area are in abundance, it still makes good business sense to process that material as efficiently as possible. Powered by CDE hydrocyclone technology, J. Lee Milligan will benefit from excellent control of cut points to increase in-spec sand recovery with their new EvoWash. This flexibility means the business will be able to respond to the needs of customers and the market in an agile way to really accelerate the return on their investment.”
SWAP YOUR SCREW
In Fall 2023, we launched a new campaign to enable operators to trade-in their old, less efficient sand screws. With data from USGS (United States Geological Society) indicating that in some of the most densely populated urban centers across the United States demand for sand and gravel reserves often outstrips supply, CDE launched the campaign to support natural sand producers to adopt modern technological solutions to drive efficiency across their operations.
A compact, modular sand washing system, the EvoWash screens and separates the smaller sand and gravel fractions through an integrated high-frequency dewatering screen, sump and hydrocyclones which provide unrivaled control of silt cut points and eliminate the loss of quality fine material with significant commercial value to settling ponds.
