Highly comprehensive range of dewatering options for fine materials including screw dewaterers, bucket wheels, and hydrocyclone technologies, all proven on a global basis.  Unique ability to offer off-the-shelf ready-made products or to design complete bespoke solutions.



The Terex® FM Compact range are static sand recovery units designed to be both cost and energy efficient.
The range uses centrifugal force within the cyclone(s) to remove clay, silt and slime from sand to bring it into specification. The range combines a collection tank, centrifugal slurry pump(s), hydrocyclone(s) and a dewatering screen on a single chassis.


  • Underflow rubber lined slurry pump(s)
  • Two rubber lined hydrocyclone(s)
  • Self regulating cyclone tank
  • High frequency dewatering screen fitted with polyurethane modular mats
  • Maximum recovery of material above 75μm (200 mesh)



The Terex® T Range are mobile bucket wheel dewaterers complete with fines retention screw, twin bucket wheel designed units for the removal of clays, silts and slimes to produce up to 2 grades of sand.
The T Range is designed to operate with maximum versatility and can support different requirements such as maximum retention of fines or maximum disposal of fines.
The T Range can be driven hydraulically from the M Range or from its own optional electric power pack.


  • Can recover 1 or 2 grades of sand from wet feed or bolt-on boiler box option for direct dry feed
  • High capacity variable speed twin bucket wheel providing increased drainage time for a drier product
  • Deep fluted variable speed fines screw provides excellent fines recovery
  • Anti-turbulence inlet boxes and weir discharge system allows consistently calm settling conditions



Terex Washing Systems offer a range of dewatering screens. Their rugged construction is designed to combat a range of applications.
Whilst primarily applied for dewatering with retained fines they are capable of being used in a wide range of applications.
The screen incorporates a 45° sloping back deck section, fitted with slotted apertures across the direction of flow. The main deck of the screen slopes upwards at 5° vibration is produced by two exciter motors operating at 980rpm.


  • Dewatering screen, catchbox and chutes combined onto a single frame
  • Exceptional dewatering performance
  • Modular screen decks
  • Side protection liners
  • Rubber lined discharge chute
