Dear Sir,

We have pleasure to inform you that we are manufacturing speciality

chemicals for various industrial applications. We have Dust

Suppression products range 'DUSTRON' for the dust suppression in

mining operation for haulage road in open cast mines and for the bulk

material handling systems.

We have a Memorandum of understanding (MOU) with Central Mining

Research Institute (CMRI) Dhanbad, India which is a part of Council

of Scientific & Industrial Research Govt. of India. CMRI is the world

recognised institute for the research in the field of mining operation.

The following products are approved and accepted by the Indian Mining

Industries since last 10 years for better environmental and mining

conditions.

1. DUSTRON PC Compound: For the open cast mines haul road where the

dust emission is because of heavy earth movers of high capacity trucks

Dozzer, Tippler etc. DUSTRON PC is used for various classes of mines

in India for dust suppression in the mines as below.

(1) Iron Ore Mines

(2) Zinc Mines

(3) Lime Stone Mines

(4) Copper/Chromite Mines

2. DUSTRON PC COAL: For the open cast mines haul road of collieries,

railway sidings and coal jetty's road of the ports.

3. DUSTRON PC LIGNITE: For the haulage roads of lignite open cast mines.

4. DUSTRON XT: This product is used for the dust suppression of bulk

material handling system where at the transfer point crusher house,

dumper platform dust emission is heavy, so along with water spray

DUSTRON XT is used to control dust emission.

5. DUSTRON XT COAL: For bulk material handling system of conveyors,

dumper platform, wagon tipplers of open cast/ under ground mines,

Thermal power plants and coal jetty on the port trust.

All the above products are used in Indian mining industries to control

dust for better environment & working conditions which produce number.

of advantages.

We hope that you might be consuming a product for similar application.

"Using DUSTRON RANGE OF PRODUCTS SAVINGS IN WATER is 40%" with other

benefits.

If you find any interest we shall send you the detail literature for

your reference along with quotation.

We ensure you to provide you best services and technical back-up to

your mines for dust suppression applications.

Awaiting your valued inquiry.

Have you looked into using calcium chips. A little expensive if using over a large track but no water required. If you have some access to water you may liquefy the calcium to cover more area. ■

Water spray is essential. Your fluid costing is the issue. Water saved price versus additive cost. Vehicle movements could be controlled to reduce bowser trips but it's a tall order. ■

Have you tried Calcium Chloride? It is hygroscopic, absorbs moisture from atmosphere and remains moist. It is a low cost material. ■

Calcium chloride is also used in mining operations for the stabilization of the unpaved haulage roads, as its application improves the strength of the road surface. Apart from keeping the dust level down, its use also reduces the overall road maintenance cost substantially. ■

This application is for a quarry in KSA where there will be very little, usually none, moisture in the atmosphere for at leat 10 months of the year. If the CaCl is applied dry; what is the injurious dust hazard created?

I have often seen asphalt paved roads torn up due to wheel bearing pressures and tractive efforts. What depth of CaCl2 is envisaged to realistically strengthen an unpaved road surface?

All chlorides are water soluble so what happens during the wet month? ■

we have several methods of additive that wil solidify the road providing there is a base below the upper level. odourdust@aol.com if you want more information ■
