Expert Tips for Operating and Maintaining a Sand Classifying Tank!

If you are in the mining, construction, or industrial sectors, chances are you understand just how valuable sand classifying tanks can be. The machine is essential for quarries processing sand, offering superior productivity and quality by precisely segregating grains of sand. By utilizing a tank to sort sand particles accurately, businesses will benefit from years of equipment utilization and increased profitability—making it an attractive option for all industries!

And while you might already know how amazing a sand classifying tank can be for your application, you might not be as well-versed in operating and maintaining it for the best performance. That’s where Kemper Equipment comes in! We want to help you get the best results from all your sand-classifying tank operations.

What is a Sand Classifying Tank?

A sand classifying tank is a type of mineral processing equipment. It works by separating sand particles according to their specific gravity, which means easier removal of the grain sizes you don’t need for your operation. The tank consists of a series of closely spaced, perforated screens or plates arranged in an inclined position. As the sand is fed into the tank, it passes through the screens where the lighter particles are removed and collected by a reservoir below the tank. The heavier particles remain on top of the screens and pass over to an exit chute. The sand particles collected in the reservoir can then be used for various purposes or sent to a screening system for further processing to achieve the right size for your product.

How Classifying Tanks Work

The sand classifying tanks use a combination of settling rates and mesh sizes to organize the sand into categories based on their specific gravity. A fine material screw washer is typically included in each tank, allowing efficient processing of all incoming materials. After mixing the sand with water, it’s fed into the tanks, separating according to its unique weight.

As the sand settles, finer particles accumulate along the length of the tank, and heavier grains settle toward its base. To help quarry owners obtain a high-quality spec product, this tank is equipped with a valve station to remove residual water quickly.

The Importance of Sand Classifying Tanks for Various Industries

Quarry businesses that process sand must produce specific grades that meet the needs of their clients. Different industries require sand of different grades, and meeting those requirements is crucial to maintaining good relationships with clients and securing repeat business.


The construction industry often requires sand with a specific particle size distribution for concrete production. Construction-grade sand must be free of contaminants and have the proper grain size component since its quality directly impacts how strong and long-lasting the final products will be.


Mining operations often utilize sand classifying tanks to separate sand from gravel and other particles and rid sand of silt and clay. The sand classifying tank passes a slurry solution through several vibrating screens designed to remove silt, slimes, and clays.

Other Industries

For various other production lines, including glass manufacturing and foundries, it is essential to have sand of exact specifications for operations. For example, if the sand has too much fine material, it can lead to poor mold strength and decreased casting quality in foundries. Similarly, improper sand classification in glass manufacturing can result in defects and decreased product quality.

Proper Maintenance Techniques for Sand Classifying Tanks

As with any other equipment, you should routinely maintain sand classifying tanks to guarantee optimal performance. Below are some essential maintenance procedures that quarry operators must consider:

Regular Cleaning

Keep your sand classifying tanks in the best condition through regular, scheduled cleanings. Allowing sand and other debris to accumulate within the tank can significantly reduce the performance of a sand classifying tank and add additional expenses to your operation for maintenance—something every quarry owner wants to avoid! Cleaning out your sand classifying tank frequently is essential for the best operational results.


Consistently and properly lubricate the gears and bearings of sand-classifying tanks to protect them from wear-and-tear damage. If these components are not maintained, they will become worn down faster over time, resulting in reduced efficiency and more replacements, meaning you will spend more money. To ensure your quarry operates at maximum productivity with minimum costs, keep up with regular maintenance on the sand classification tank’s parts!


Regular inspections are essential for detecting developing issues before they become significant problems. Additionally, consistently performing preventative maintenance and closely examining the sand classifying tanks for signs of detachment, dirtied filters, or other indicators that could signal a requirement to maintain it is paramount. When you take these preventive actions, you can save money on unnecessary downtime and extend the life span of your equipment.

Replacement Parts

As time passes, components of the sand classifying tank may become outdated and require replacements. You may want to keep a stock of replacement parts on hand so that you can quickly replace any worn or damaged components as you notice them.

Operating Procedures

Sticking to the established operating procedures for successfully operating the sand classifying tank is best. Quarry operators should develop and maintain consistent protocols for their sand classification tanks to decrease potential danger and maximize the overall performance of the equipment.
