Dewatering Screen

The dewatering screen is a specialized vibrating screening equipment designed for high-moisture materials such as slurries and muddy sand. It is capable of performing dewatering, desliming, and media removal operations, and is also widely used in tailings dry stacking and sand & aggregate processing.

Relying on linear reciprocating vibration to accelerate moisture separation, and equipped with an adjustable screen inclination, this equipment delivers excellent dewatering performance. Its main body consists of a reinforced steel plate screen box, dual vibration motors, rubber springs, and various screen mesh materials. With a robust structure, it is highly adaptable to automated production lines, offering both environmental and economic benefits.

Widely applied in the dewatering processes of raw coal in coal preparation plants, finished quartz sand in mining, and materials in other new energy industries.

ADVANTAGES

1.High Efficiency & Energy Saving: High-frequency vibration accelerates moisture separation, reducing power consumption by 30% compared to traditional processes. The linear motion effectively prevents material from clogging the screen apertures.

2.Durability & Low Consumption: The screen panels are made of polyurethane, offering a wear resistance up to 5 times that of ordinary materials for an extended service life. The spring vibration-damping design ensures low-noise operation.

3.Flexible Maintenance: Modular screen panels allow for quick replacement, and the vibration motors are easy to dismantle, significantly reducing downtime.

4.Strong Adaptability: The screen surface features a negative inclination design (-5° to 0°) to enhance dewatering performance. This ensures high processing capacity and low moisture content for dry-stacked tailings.

5.Lightweight & Robust: The steel structure components are assembled using a combination of riveting and welding. This method is superior to pure welding, providing greater structural strength and durability.

6.Technical Upgrades: Specially designed spliced screen panels significantly increase the dewatering area. Additionally, screen panels are also laid flat at the feed end, further boosting the equipment's processing capacity.

PRODUCT STRUCTURE

Driven by two synchronous counter-rotating motors, the centrifugal forces generated by the eccentric blocks superimpose in the same direction and cancel out laterally, causing the screen box to vibrate linearly at a high frequency.

Upon entering the feed end, the material first passes through a 45° inclined screen panel, which rapidly removes approximately one-third of the moisture. The remaining material then accumulates to form a filter bed, which is progressively compacted under continuous vibration. Combined with the negative inclination design of the screen surface, the surface water flows backward and converges. Ultimately, the material is discharged in the form of a dry filter cake.
