Washing & Screening
McLanahan UltraWASH provides Tri- Parish Sand and Gravel with clean product in a compact, modular plant
Tri-Parish Sand and Gravel is a dry mining operation located in Walker, Louisiana. They produce C-33 concrete sand, pea gravel and #57 concrete gravel for use in their ready-mix operation, Parish Ready Mix...
Challenge
James Nolan, who owns Tri- Parish Sand and Gravel with his wife, Gail, has always been concerned about the cleanliness of the products they use in their ready-mix facility. They strive to deliver quality products on the concrete side of their business, which starts with the material used to make those products.
To better control the quality of
their concrete products as well as lower their production costs so they could pass those
savings onto their customers, the Nolans purchased land for dry mining their own sand and gravel. They looked at a few wash plants in different parts of the country for processing the feed and separating it into the various products needed at their ready-mix facility.
Solution
In 2020, Tri-Parish purchased the McLanahan UltraWASH 6206 Modular Wash Plant that debuted at CONEXPO/CON-AGG in Las Vegas. Availability was a key factor in the purchasing decision. Tri-Parish needed a wash plant quickly, and the McLanahan UltraWASH offered an entire wet processing plant in one compact, modular unit that was ready to run.
“We bought the plant, and we’re very, very pleased with it,” James Nolan said. “It definitely does way more than they said it would do.”
The UltraWASH features a McLanahan Inclined Vibratory Screen for sizing up to three aggregate products (the oversize, the pea gravel and the #57 gravel in Tri-Parish’s operation). It also features a sump, two McLanahan Pumps, two McLanahan Hydrocyclones and a McLanahan
Dewatering Screen for washing, classifying, and
drying the sand product. This particular
UltraWASH model is a double wash system,
which processes the sand twice before
discharge for a cleaner end product.
A modular plant, the UltraWASH arrived at Tri-Parish in several partially pre- assembled and pre-wired pieces.
“It went together very easily,” said Operations Manager Danny Graham. “You could almost do it by pictures alone.”
Graham added that the modularity of the UltraWASH would be beneficial if they need to move the plant closer to the area in which they are mining in the future.
“It could be somewhat portable. Youcantakeitandmoveitina matter of a day or
two,” he said.
