H2OSCAN ANALYSER

The H2OSCAN On-Belt Moisture Measurement System now allows the accurate measurement of moisture in real-time. This ready availability of moisture information allows proactive process control actions. The information can be used in several ways including:

Metallurgical/process accounting
Diverting excessively moist material away from vulnerable downstream processes
Feedback control to a dryer circuit
Feed forward/back control to spray bars for dust control
Product nett weight monitoring for quality control purposes
Product moisture/dry mass contract compliance, etc., etc.

APPLICATIONS

Suitable for continuous, on-conveyor applications ranging from conventional non-conducting materials to moderately attenuating materials such as iron ore, chrome, minerals concentrates and high moisture coals.

SYSTEM DESCRIPTION

The H20Scan on-belt moisture analyser consists of the following sub-systems:

Measurement H-bracket:

o Sturdy H bracket securely mount H2OScan over the conveyor by bolting to conveyor structure

Easily adjusted to fit existing conveyors

Ensures accurate alignment of the microwave transmitter and receiver subsystems.

Electronics control cabinet: Mounted on H bracket or separate fixture. Contains electrical, electronic hardware which consists of:

o Processor / PLC

o Power supplies

o Electrical terminations

Analogue or digital inputs and outputs

Profibus standard – Modbus/Ethernet etc. available

Mass flow measurement:

o Usually provided using a belt scale or weigh feeder. H2OScan can interface with this device for the calculation of weight percent moisture. For applications with no measurement device H2OScan can be supplied complete with an integrated belt scale.
