Classifying Tank

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.

Applications:

Manufactured Sand

Sand & Gravel

Fines Retention

Dredging

Water Scalping

Rock Face to Load Out®

Near Nashville, Tennessee, Hoover Materials uses a single Classifying Tank in production of their masonry and C33 sands.

Advantages

Feature01 - Classifying Tank - Elevated Valve Bridge
01.

Elevated Valve Bridge

At least 6” higher than competitors, which prevents water from damaging mechanical parts.

Feature02 - Classifying Tank - Control System
02.

Control System

Computer controls maintain tight specifications, can be controlled from anywhere, and save spec recipes.

Feature03 - Classifying Tank - Valve Station
03.

Valve Station

High pressure hydraulic hoses encourage faster valve opening and closing, which achieves a more precise spec.

Feature04 - Classifying Tank - Recirculating Pump
04.

Recirculating Pump

Reduces water usage by recycling tank overflow to the rising current cells.

how classifying tank works dk

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.

Classifying Tank

Application
Blending of construction aggregates.
Action

Feed is separated and blended into spec products.

Feed equipment

Accepts feed from multiple types of equipment.

feed material

Handles variable feed well.

Water usage

High

Yield

Unit overflow can displace valuable fine sands.

footprint

Large

Maintenance

Multiple moving valves and gauges per station.

Density Sizer

Application
Specialty products like frac or filter sands and glass.
Action

Extremely sharp cut splits feed in two.

Feed equipment

Typically only takes its feed from hydrocyclones.

feed material

Works best when feed is consistent.

Water usage

Low

Yield

No overflow products lost to waste pond.

footprint

Compact

Maintenance

Less with only one moving part to maintain.
