DOVE Dewatering Screens, also referred to as Dewatering Vibrating Screens are highly efficient type of classifiers, well known in the industry, used for quantitative feeding of material for wide variety of applications, including Dewatering, Desliming, Rinsing, Sizing and Washing, Degritting, for various material.

DOVE Dewatering Screens are highly efficient equipment to dewater various material such as Sand, Gravel, Coal, Crushed aggregates, Mineral sand, Iron Ore, Precious and semi-precious metals, Frac sand, and other granular material.

DOVE supplies the largest range of Dewatering Screens, in 10 standard models, with capacity range of 5 – 350 TPH, with screen widths from 800 –2,400 mm  wide, and 2,000-6,000 mm long.

• DOVE Dewatering Screens are the most efficient dewatering equipment in the industry, designed to produce continuous and consistent drip free materials.
• DOVE Dewatering Screens are efficient replacement of Rake classifier, and Rotary sand Screw classifier for dewatering applications.
• DOVE Dewatering Screens are available in 10 Standard models, supplied in various screen mesh sizes, the screens are fabricated from heavy duty Polyurethane screen media, or in special requirement from Stainless steel.
• The Polyurethane screens configured in DOVE Dewatering Screens are fabricated from polymer Polyurethane (UHMW-PE), highly impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, and high absorption impact energy.
• DOVE Dewatering Screens are fabricated with highest level of design, quality, and performance to operate consistently in even the most rugged and demanding site conditions.
• DOVE Dewatering Screens are designed with advanced Trunnion suspension, and heavy-duty Coil springs.
• The DOVE Dewatering Screens are designed with two separate vibrating motors configured for synchronous reverse operation. The motors are fixed with high strength bolts, the unit is also configured with high quality rubber springs to reduce the effect of vibration to the machine and the motors, increasing the life of the motors, as well as reduce the vibration noise.

DOVE Dewatering Screens are designed for wide range of applications as per following:

DOVE Dewatering Screens are highly efficient equipment designed as linear Vibrating Screen that widely applied in various industries for applications of Dewatering, Desliming, Washing, Degritting, and Screening.

DOVE Dewatering Screens are efficient replacement of Rake classifier, and Rotary sand Screw classifier for dewatering applications.

To dewater the material, the slurry is fed uniformly to one end of the steep, downward inclined screen, by vibrating feeder, or directly from sand washer, or other equipment like concentrators. The solid material is retained on the screen, while the slurry water drains from the screen bed and flows through the screen aperture. The screen deck configured with slop upward at 5 degree and is fitted with slotted aperture.

The vibration movement of the dewatering Screen is caused by two counter rotating vibratory motors, designed to create a linear motion at an angle to the screen surface that accelerates the solid particles upward and forward at five (G) force. This vibration force induces the bed of solids to move along the screen that is a complex function of the mechanical action and of the properties of the bed itself. The water gets detached from the solid particles by the abrupt reversal of vibrating motion. The solids move up the screen bed by the linear motion and the water droplets through the screen aperture.

The solids particles on the screen bed move forward towards the outlet end of the screen and eventually conveyed to stockpile. The water is pumped to the retention recycling dam.
