Classifiers Blend to Exacting Specs
Common in dredging or sand applications that require removal — or scalping — of lots of water, Classifying Tanks are capable of accepting a variable out-of-spec feed and will produce a steady in-spec output.
Using a system of high-pressure valves that are computer-controlled, feed material is blended together according to your inputted spec.
Sand classifiers can produce as many as two spec products and one excess product.

Elevated Valve Bridge
At least 6” higher than competitors, which prevents water from damaging mechanical parts.
Computer controls maintain tight specifications, can be controlled from anywhere, and save spec recipes.
High pressure hydraulic hoses encourage faster valve opening and closing, which achieves a more precise spec.
Reduces water usage by recycling tank overflow to the rising current cells.
How Does A Classifying Tank Work?
A sand/slurry mix is pumped into the tank through a feedbox. Particles drop in the tank as the velocity of the water slows and allows the material to settle. The coarsest, heaviest sand falls earliest in the process while finer sands settle at the end of the tank.
At the bottom of the tank, valves open and close at different intervals releasing a specific amount of sand from each station. This motion is controlled by the computer according to the blended specs you entered.

Comparing Classifying Technology
When it comes to technology for classifying dry bulk materials, classifiers and sizers are often compared. This table will help you separate broad features of each.
Blending of construction aggregates.
Feed is separated and blended into spec products.
Accepts feed from multiple types of equipment.
Handles variable feed well.
Unit overflow can displace valuable fine sands.
Multiple moving valves and gauges per station.
Specialty products like frac or filter sands and glass.
Extremely sharp cut splits feed in two.
Typically only takes its feed from hydrocyclones.
Works best when feed is consistent.
No overflow products lost to waste pond.
Less with only one moving part to maintain.
Classifying Tanks are included in Lyman-Richey’s compact washing plant.
Cemstone Products appreciates the precision of material from a Classifying Tank.
