Aggregate Washing Equipment

The unsung hero of many aggregate processing operations, a well-engineered washing plant helps producers achieve superior product sizing and classification by removing clay, silt, dirt, and other debris from product. As specifications become more stringent, washing equipment like screw conveyors, log washers, and even wet dust suppression systems may be a great addition to your operation.

Are you ready to optimize your wash plant for better profitability? Here at Kemper Equipment, we've got decades of material handling and mineral processing experience at the ready to help you set up an efficient circuit—either modular or stationary—that will enhance your operation's overall performance.

Our Expertise as Washing Equipment Specialists

washing plant

Separating unwanted materials like clay, silt, and slime from valuable sand, gravel, and crushed aggregate has always been a tricky problem in processing operations.

Wash equipment has been designed and perfected to solve this issue while also assuring that construction aggregates and sand can meet ever more stringent specifications and be saleable.

At Kemper Equipment, we offer heavy-duty washing equipment that will bring a new level of flexibility to your operations. We are experts at designing new custom wash plants and retrofits into existing operations. As with all the equipment we supply—from crushers to screens to conveyors—operators must have a solid understanding of their operating parameters and overall production goals to decide which equipment will work best.

The good news is, you don't go it alone when choosing any aggregate processing equipment because you can put our production experience to work for you. Kemper experts know the types of washing equipment and other solutions that will work best based on your requirements, and more importantly, your budget.

Types of Wash Plant Equipment

Wash plants may feature several different equipment options working in combination, including portables and stationary units. Sand classification tanks, dewatering screens, coarse and fine material washers, and other wash equipment might make up a profitable washing plant.

The main point to remember is that washing benefits most from a customized approach to system setup and design—and Kemper Equipment can help.


Fine Material Screw Washer

Sand Screws / Fine Material Screw Washers

Available from a variety of industry-leading equipment manufacturers dedicated to producing the best solutions for washing and classifying, the name "sand screw" describes the mechanism in the machinery itself—it looks like a screw and processes sand. Many sand screw plants now feature two rotating, independently-driven screws to dewater, classify, and wash minus 3/8-inch sand or other fine material.

Log Washers

Some of the original washing equipment, log washers have been around since the 1890s—and they are still an excellent solution for ore and stone washing and more. Many can accept feed material up to 6" cubed and scrub away clay and other deleterious materials with material-on-material action. Modern log washers are designed with a focus on safety and ease of operation.

Wet Dust Suppression System

Dust Suppression Systems

No matter how dialed in your production processes are, dust can be the "devil in the details" plaguing your rock, sand, gravel, or mineral processing operation. The good news is there are many dust suppression options out there today—and wet dust suppression systems, which are often classified as washing equipment—are highly effective.

What About Dewatering Equipment?

washing plant

Washing is not the end of the processing circuit—at least, the addition of water to material in order to clean, size, classify, or separate it is not the final step in a processing operation. Dewatering is an important consideration that every operator, especially those of fine aggregates and sand production businesses, must make following washing.

What is Dewatering, and Why is it Done?

In short, dewatering is precisely what it sounds like—it is the extraction of water following the "wet" stages of washing and classifying material. It serves two primary purposes: additional material recovery and the sufficient reduction of moisture content before stockpiling.

Dewatering is Especially Important for Sand Production

Sand production involves horizontal sand classifying tanks that rely on water and the principles of gravity to separate material that has been screened smaller than number 8 mesh. Because hydraulic separation is necessary to claim the smallest sand particles, water becomes a significant force to contend with, and dewatering cannot merely be an afterthought.

Luckily, sand is easily processed through dewatering screens and may also be dewatered with sand screws, among other equipment.

Dewatering Equipment Options

Traditionally achieved with dewatering screens in both aggregates and industrial sand production, some washing solutions integrate dewatering into a single piece of equipment, such as sand screw plants. Bucket wheels are another popular piece of dewatering equipment, which boast sand recovery of up to 99.5%.

Because dewatering screens are designed to produce a consistent, drip-free product and can remove dirt and silt while retaining sand down to 100 or even 200 mesh sizing, they tend to be the go-to equipment for dewatering. In fact, dewatering screens can typically achieve much better drying than screws or other, less commonly utilized dewatering equipment.

Washing and Dewatering: Better with Kemper

Many washing equipment solutions now include dewatering equipment—in the form of screens or screws—integrated into a single module. This washing equipment may consist of sand screws, bucket wheel plants, and even hydrocyclone technology. So how do producers choose the best washing solutions?

The best way to find the right wash plants and other aggregate equipment—as well as replacement parts—for your operation is to work with a knowledgeable material handling solutions partner like Kemper Equipment.
