Dewatering Screen
-
Superior Dewatering & High Fine Sand Recovery: Discharged aggregate moisture can be reduced to 10%-15%. Matched with cyclones to recover lost fine sand, raising finished output and cutting raw material loss.
-
Wear-resistant PU Panels, Anti-clog & Long Service Life: Integrally cast polyurethane panels have 3 times higher wear resistance than steel mesh, anti-sludge-clog design and longer replacement cycle to cut maintenance cost.
-
Heavy Waterproof Body, Stable Operation Under Harsh Conditions: Fully sealed waterproof body with waterproof vibration motors supports long-term continuous operation in mist and slurry environment. Riveted welded screen box resists deformation and cracking.
-
Bottom Water Collection Tank for Water Recycling: Built-in water collecting tray gathers wastewater and recycles it back to sand washing system, saving water and meeting environmental discharge standards.
1. Product Overview
Dewatering vibrating screen is a high-frequency linear vibrating solid-liquid separation machine. Equipped with dual vibrating motors to generate directional linear exciting force, it adopts negatively inclined segmented screen surface and wear-resistant polyurethane screen panels. It is specially used for dewatering and desliming high-moisture slurry such as washed sand, mine tailings and coal slime, which greatly reduces material moisture and recovers fine sand to minimize loss. Built with heavy riveted welded structure and waterproof sealing design, it is often matched with hydrocyclones and sand washers, the standard dewatering equipment for aggregate, mining and coal production lines.
2. Detailed Description
Two vibrating motors run synchronously in reverse directions to generate 45° directional high-frequency throwing vibration. Wet slurry falls on inclined screen surface from feeding end: the first section realizes rapid gravity drainage, while the elevated second section squeezes materials to remove capillary water. Water and ultra-fine silt pass through panels into the bottom water tank for recycling, and dry aggregates move forward along the screen for discharge. Polyurethane panels with self-cleaning structure reduce silt clogging; exciting force and amplitude are adjustable to fit slurry of different concentrations.
3. Materials
Washed aggregate, silica sand, mine tailing slurry, coal slime, mineral powder, river dredging fine sand, manufactured sand, kaolin, flotation pulp, construction mud and other wet granular slurry.
4. Why Choose Us
-
High-frequency & low-amplitude linear vibration, high solid-liquid separation efficiency: Adopts dual-motor self-synchronous linear vibration to break material water film rapidly and strip free water. Suitable for sand washing wastewater, coal slime water and mine tailings slurry to realize continuous automatic dewatering and water recycling.
-
Negative-angle climbing screen surface, no slurry backflow & lower moisture content: The -5° negative-angle climbing design ensures steady material conveying and rapid slurry penetration, avoiding water accumulation and backflow. Finished materials with stable low moisture can be directly stacked and loaded.
-
Wear-resistant polyurethane screen plate, anti-clogging & long service life: Elastic polyurethane screen plates realize automatic self-cleaning to prevent fine sand and slime blockage. Higher wear and corrosion resistance greatly reduce replacement frequency and downtime compared with stainless steel screens.
-
Complete fine material recovery system, greatly reduce resource loss: Optimized for 0.075–5mm fine particles. Cooperated with hydrocyclones to intercept and recover fine materials effectively, solving fine material loss and output shortage problems to improve economic benefits.
-
Fully enclosed low-noise operation, low dust & wide working condition adaptability: Stable linear vibration with no severe jolt and fully enclosed structure greatly reduce dust emission. Low noise and small vibration conduction require no heavy damping foundation, realizing rapid installation in various factories.
-
Modular integrated structure, simple maintenance & low operation cost: Integrated modular design with standardized components of vibrator, screen body, shock absorber and water tank. Only simple daily maintenance is needed, supporting 24-hour heavy-duty stable operation with low long-term operating cost.
