McLanahan Offers Classifying Tank Based Sand Plants with Fine Material Screws or Ultra Sand Plants
Sand Classifying Tanks have been a staple in the construction aggregates industry for more than 50 years. Also known as water scalping tanks, Classifying Tanks efficiently handle large amounts of water and offer the ability to create multiple specification products from one feed.
Classifying Tanks are divided into sections known as stations. As the sand slurry enters the sand tank, product sized sand particles are separated in successive sizes down the length of the tank, with coarse particles settling in the stations at the front of the tank, medium size particles settling in the middle and fine particles settling in the stations at the end of the tank. Valves in each station discharge sand to reblend the particles to a certain specification via a collecting flume and then discharge to dewatering equipment, such as Fine Material Screw Washers or Dewatering Screens, ahead of stockpiling.
