Overview
Dewatering screens are vibrating or inclined screens used in crushing and screening plants to remove water from sand, gravel and fine aggregates. They separate solids from slurry to produce drier product, reduce transport costs and improve downstream processing. Common in mining, construction and dredging, they use features like polymer mats, wedge wire or perforated decks and adjustable slope/vibration to boost throughput and drainage efficiency.
FAQ
What should I check when buying a used dewatering screen?
Inspect the condition of the deck/mats, frame and drive components, bearings, motors and electrical controls. Verify capacity, feed/discharge configuration, wear parts availability and maintenance records. Check for corrosion, weld repairs and whether hydraulic or electric systems operate correctly.
How do I prepare a dewatering screen for shipping?
Secure or remove fragile attachments, drain fluids, lock moving parts and protect mats and decks. Disassemble large sections if needed for transport, label connections and use certified rigging. Confirm dimensions/weight for permits and choose a carrier experienced with screening plants.
What regular maintenance keeps a dewatering screen working well?
Keep mats and decks clean, check and grease bearings, inspect drive belts/chains and motors, monitor vibration and slope settings, and replace worn liners or mats. Schedule inspections after heavy slurry loads and maintain water distribution nozzles to prevent clogging.
