Lipu Dewatering Screens remove water from slurry and fine materials for tailings, sand recovery, coal slurry, and mineral processing. Dual-motor vibration delivers efficient dewatering and a drier discharge.
A dewatering screen is a vibrating screening machine used to separate water from fine solids. Wet material is fed onto the inclined screen surface, where vibration conveys solids toward the discharge end while water passes through the screen openings.
It is widely used where lower moisture content, improved material recovery, or efficient slurry handling is required. Typical applications include mineral-processing tailings, washed sand, coal slurry, quartz sand, ceramic slurry, and fine aggregate.
The screen is driven by two vibration motors operating in synchronized opposite rotation. Their combined force creates linear vibration, moving material along the inclined screen deck.
The screen angle, vibration amplitude, frequency, and screen opening can be selected according to material characteristics and required dewatering performance.
High-frequency linear vibration helps release free water quickly and improves solid-liquid separation.
The inclined screen surface promotes drainage and produces a more manageable solid product for stockpiling, transport, or further processing.
The rigid frame and dual-motor drive support continuous processing of high-flow slurry and fine materials.
Screen media and contact surfaces can be selected for abrasive materials to reduce wear and extend service life.
Polyurethane, rubber, wedge-wire, or other suitable screen panels can be configured according to particle size, abrasion level, and dewatering target.
Modular screen panels and accessible drive components simplify routine inspection and replacement.
A Lipu Dewatering Screen typically includes:
Each component works together to maintain stable vibration, effective drainage, and reliable material transport.

FAQ
What is the main purpose of a dewatering screen?
It removes free water from slurry and wet fine materials, producing a drier solid discharge.
Can a dewatering screen recover fine sand?
Yes. It is commonly used in sand washing and sand recovery systems to retain fine particles while removing excess water.
What screen media is suitable for abrasive materials?
Polyurethane and rubber screen panels are commonly selected for abrasive mineral sands and tailings because of their wear resistance.
Can the machine handle tailings slurry?
Yes. Dewatering screens are widely used for tailings dewatering and water recovery in mineral-processing plants.
