Dewatering screens are one of the most common and efficient types of dewatering equipment, using high-frequency vibration to separate water from solids. Depending on the application, complete dewatering systems may also include hydrocyclones, pumps, and material handling equipment to achieve the desired moisture level and throughput.
Dewatering equipment is widely used in industries such as:
Different applications require different equipment configurations depending on material type, particle size, and moisture content.
Dewatering equipment is used across a wide range of industries to improve material handling and processing efficiency.
What is dewatering equipment used for?
Dewatering equipment removes moisture from bulk solids to improve handling, storage, and processing.
How do dewatering screens work?
They use high-frequency vibration to separate water from solids through a fine mesh screen.
What moisture levels can be achieved?
Final moisture content depends on material type and system design but is typically reduced to a stackable level.
What industries use dewatering equipment?
Common industries include mining, aggregates, frac sand, chemicals, and recycling.

Stack Sizer®, Dewatering Machines, and Polyweb® Urethane Screens Improve Frac Sand Production
Category | Derrick Screens & Screening Machines | Dewatering Equipment & Screens |
A wet frac sand tailings stream is processed to recover valuable product before wet sand tailings are sent back to a quarry. Water and silica sand are processed over a urethane screen panel designed to remove any remaining product from the tailings stream.

Three vibratory screens are used to scalp oversized silica sand particles in a wet screening application. Sand and water are fed from a water separator onto the screen’s surface. All sand particles larger than 40 mesh are scalped off and removed from the flow.

A sand producer was looking to increase production rates at an existing plant by adding new frac sand screening equipment. Their goal was to produce a consistent 40 x 70 API standard product. The feed to the vibratory screening machines would be from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 STPH.

Derrick Stack Sizers 5 deck for fine screening and dewatering mineral processing
The Derrick Stack Sizer is a high-frequency, multi-deck screening machine used for fine screening and dewatering in mineral processing applications.
It is designed to achieve high screening efficiency, high capacity throughput, and a significantly smaller footprint compared to conventional screening equipment.
Stack Sizers are commonly used for separations down to 38 microns and are widely applied in mineral sands, iron ore, silica sand, and other high-tonnage processing operations.
It is a much better alternative to hydrocylcone separators, hydraulic classifiers, and less efficient low volume screening systems.

Integrated dewatering system with double roll crusher
This continuous and automatic dewatering system turns wet petroleum coke slurry and sludge into dry solids that can be stacked or conveyed easily. The system requires little or no maintenance and is not affected by the amount of water in the solids. It can be stationary or mounted on tracks and rails.
This type of dewatering system fits most coking applications. It can also be used for other types of bulk solids that require industrial scale drying before loading onto rail cars, trucks, barges, or ground storage. It uses the principle of two-mass, natural frequency, sub-resonant magnification. This means that a small exciting force acts upon a coil spring amplification system to alternately store and release energy and move material in a shuffling motion.

A waste wood power boiler uses a wet scrubber to remove ash from the boiler system. The water containing unburned carbon (char) and sand with grit is then pumped at a rate of 2,300 GPM to vibratory dewatering screens. The urethane screen panels remove the char and most of the sand and grit from the water. These solids are then moved by conveyor or front end loader to the wood yard. The water is sent to the clarifier system for further solids removal. The unburned carbon is re-injected into the boiler as fuel.

Final dewatered ash, or char, being fed off the dewatering screen
This boiler ash handling and recovery system is designed to remove unburned carbon (char), ash, grit, and sand from wastewater discharged from a wood and bark power boiler. Slurry, composed of water and solids, is sent from the wet precipitator to the dewatering screen at rates of 800 to 2,200 GPM. The HI-G dewatering screen uses (2) low horsepower, industrial vibration motors to apply a high G-force on the urethane screen panels. This separates the water from the solids.

Fluid bed dryer for pre-crushed pumice
This vibrating fluid bed dryer is used to remove the surface and internal moisture from pre-crushed pumice. The ore enters the system via a belt conveyor and feeds the dryer. Air heated by natural gas is processed through the fluid bed dryer, removing the moisture. Moisture laden gas is sent to a dust collector to remove any entrained fines before the gas is released into the atmosphere. The dried ore is then discharged from the dryer onto a conveyor and sent to a storage silo.
