Beneficial effect of the present invention:

1. dust prevention and control successful, administers dust thorough, has realized the transformation for the treatment of flour dust from " taking stopgap measures " to " effecting a permanent cure ".

2. this method starts containment from source, and material arrives after stockpiling area, does not also substantially have dust and produce in the process of windrow, reclaimer feeding.

3. the main component of dedusting ash is mineral dust, and mineral dust is collected and is again added in material, has reduced to a certain extent the loss of ore materials.According to initial estimate, dust accounts for material thousand/six four, if every day 10,000 tons of output, the deduster amount of gathering dust reaches 64 tons, if take the airborne dust loss of empirical value 2/1000ths is 20 tons, this part loss of material can effectively be controlled, be retrieved to this method.

4. this method water consumption, in 50% left and right of spray-water, has been saved water in a large number.

5. the ash that lands is at present serious, has specially many people cleaning in 24 hours, and after improvement, deashing workload is extremely low, saves labour cost.

6. inner air quality in workshop is obviously improved, and has ensured numerous employees' occupational health.

7. after dust improves, equipment failure rate reduces, and employee patrols and examines quality and improves, and safety assurance ability improves.

8. Meteorological is extremely low, and most of material adopts maintenance repair material or waste materials to make.

9. be not subject to seasonal restrictions, be not subject to weather effect, in the time of winter, as long as mud pit, slurry tank, water pipe insulation are not frozen and can be used, regulate slip consistency to make it not be stained with belt, made up the defect that spray system cannot be used winter.
