In fact, Contract Crushing has been the heart and soul of our organization since the 1970s. We’ve partnered with small family-owned operations, we’ve helped build aggregate producer empires, and everything in between. Mellott’s contract crushing division has reached an unparalleled level of excellence in providing solutions to our producer customers in areas such as:

Understanding Wash Equipment

Wash equipment encompasses a range of machines designed to clean aggregate mixtures. This includes scrubbers, washers, and dryers. The primary benefit of wash equipment is its ability to remove debris and dirt from the aggregate mixture, thereby enhancing the quality of the final product.

Additionally, wash equipment plays a crucial role in reducing moisture content in the aggregate mixture, which is particularly essential for products requiring drying after production. Furthermore, it aids in minimizing dust generation during the manufacturing process, promoting worker safety and maintaining a clean environment.

Types of Wash Equipment

There are various options available when it comes to selecting wash equipment:

Dewatering Screens

Dewatering screens are widely used across industries to separate liquids from solids. These screens, made of wire cloth or mesh, efficiently remove liquid particles from aggregate mixtures such as sand, coal, and iron ore. This step is crucial in water treatment and wastewater management.

Screw/Log Washers

In some cases, additional processing is necessary to remove impurities like plastics and clay from aggregate mixtures. Screw and log washers provide an extra layer of cleaning to achieve desired specifications.

Screw washers utilize a screw conveyor system to move the aggregate mixture through a washing process, while log washers employ a rotating drum to cleanse the mixture.


Tanks are essential for maintaining clean equipment and ensuring optimal performance in aggregate production. They help prevent debris accumulation, which can significantly impact the longevity and efficiency of your equipment. Additionally, tank wash systems protect the environment by preventing pollutants from entering waterways. They are typically used to clean trucks, equipment, and tanks employed in aggregate production projects.

Ultra Fines Recovery (UFR) Systems

UFR systems are designed to recycle materials from processing plant tailing streams and dewatering systems. These systems effectively capture small particles released during the production of aggregates. By separating small particles from larger ones using screens, UFR systems ensure the highest quality of the final product.

Dewatering Screens

Dewatering screens are essential in wash equipment, removing water from the mix for easier handling and storage. They also improve the mix quality by filtering out impurities.

Screws/Log Washers

Screw washers use a conveyor system to guide the aggregate mix through a cleaning process, while log washers clean the mix using a rotating drum.


In the process of mixing aggregate, we use wash equipment to clean and sort rocks and gravel. This ensures the mixture perfectly matches your project’s needs. The equipment features tanks in multiple shapes and sizes, each using specialized methods to clean the materials.
