A central task in mineral processing technology involves cleaning the feed material to remove adhering fine mineral particles and to dissolve any agglomerates that it may contain. The HYDRO-CLEAN® by HAVER NIAGARA GmbH is an innovative high pressure washing system where the dirty raw material is subjected to a rotating water jet generated by a wash rotor. In a processing step the coarse dirt is removed and components that can be slurried are separated from the desired product. The system’s cleaning performance has proven itself in a number of applications worldwide.

Slim-Line System Design
Due to its compact size and weight, overall operating and
structural costs are considerably lower than with traditional
washing systems – which also require more equipment
and a greater footprint.
A traditional washing system can require up to three
screens along with a log washer or screw.
With a HYDRO-CLEAN® unit, the producer only needs an
additional wash screen for the HYDRO-CLEAN®
discharged material

Advantages and benefits
 Minimal wear, as all moving machine parts of the
washing rotor unit are located outside the material flow
 Frugal use of water as a natural resource of 0.1 to 0.2
m³ per tonne of feed raw material
 The cleaning performance has been successfully
proven worldwide in a multiplicity of applications
 Reducing the amount of rubble and effectively
increasing the proportion of usable product reduces
operating costs and increases profit

Advantages and benefits
 High throughput rate of up to 320 t/h
 Ideal for cleaning clayey/loamy components in
excavated material with a size of 0/120 mm
 Minimal water consumption reduces the amount of
waste water circulation and reduces operating costs
 High-pressure pump drive optionally with diesel
generator for use in remote regions
 Electrical control system design ranging from „high-tech“
to „keep it simple“ depending on requirements for every
application, location and type of operating personnel
 Innovative high-pressure washing system, Made in
Germany
