Conveyor dewatering
Excessive water on coal conveyors results in material slough back and spillage on inclined belts.
Water deposited into coal bins affects discharge control.
Uncontrolled material movement on conveyors or from bins is a major safety hazard which must be controlled.
Causes significant downtime, equipment damage, additional clean-up and increased corrosion.
Results in additional operational costs.
A major problem, particularly in the case of underground longwall clearance conveyors.

Conveyor dewatering
The “BRAIN INDUSTRIES” Dewatering Unit solves the
problems by removing water from the coal stream.
Designed by “WATKINS GODWIN” and now incorporated
within the Brain Industries product range.

Conveyor dewatering
Performance objective –
To ensure that downstream material acts as a bulk solid rather than
a slurry
Each unit specifically designed for –
Belt width and speed
3.0m/sec is the nominal minimum belt speed
Material lump size
Discharge pulley diameter
Available roadway dimensions
Installed at a cut through
Performance is dependant on adequate headroom
