Offering a suite of products for dust control, Rainstorm facilitates efficient solutions to reduce dust and other airborne contaminants in the mining, civil construction, materials handling and land rehabilitation industries, among others. 

With nearly three decades of experience in the dust control sector, Rainstorm Technical Manager Mason Trouchet said he was pleased to announce the company had added Dustex, a road-stabilisation and dust-control product made by Norwegian company Borregaard LignoTech, to its range. 

“Dustex will open up the market to high-quality lignins at very competitive pricing,” he said. 

“We have been blending lignins with other products in our range to add binding power now we have the history and experience of Dustex – a market leader in lignin technology.” 

Lignins are a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. 

Another product in high demand for remote roads is Rainstorm’s DustMag solution. 

DustMag is a hydroscopic material providing high-performance road compaction and dust control. 

Rainstorm produces DustMag in the North West and eastern states of Australia and hauls to mining and civil projects from Broome to Broken Hill. 

Combating blasting dust and noise 

Rainstorm has also teamed up with Pressure Wave Systems (PWS) to tackle the difficult problem of dust and noise generated by blasting, using a patented technology. 

The PWS technology replaces traditional rock stems with Stem Gel LR2, a reagent used as a containment system that has led to better blasting efficiency. 

The technology works to contain pressure waves in rock, bringing about greater fragmentation and a list of downstream benefits. 

“The liquid gel could be pumped into horizontal stems underground and in open pits,” Mr Trouchet said. 

“Stem Gel LR2 is a novel approach, and field trials through Western Australian mines and quarries have generated significant data sets to open this technology up to the wider market.” 

Point of Dust Extinction 

The above partnerships are expected to complement Rainstorm’s own ore conditioner known as Point of Dust Extinction (PDX), which enables uniform moisture wetting of fines ores. 

The cationic dispersant modifies the moisture particle relationship, creating less dust at lower moisture levels and leading to clean plant throughputs. 

“Lowering moisture in ore specifications will build the bottom line, with less water and wasted energy in ore transport,” Mr Trouchet said. 

The power of data 

New innovation driven by data is demonstrating real-time dust sources in detail, enabling targeted use of additives in problem areas. 

On roads, Rainstorm uses mobile dust trackers for vehicles on the haul/LV road circuit. Data directs water carts to specific zones for targeted dust control. 

When it comes to ore processing, real-time moisture and dust control feeds enable water sprays to operate automatically with intelligence, directing minimal water use for dust sprays and avoiding overuse that blocks screens and transfer shutes. Data provides the controls for automation.
