How to Improve Dedusting Effect of Jaw Crusher?

Many suppliers can equip the mouths of jaw crusher with dedusting devices. But, the actual dedusting effect is not very good. According to the analyzing results for dust production of jaw crusher, we deduce the reasons: heavy dust during the working process, too-far distance between dust hood and dust outlet, low water pressure in spray nozzle, few nozzle.

Or, if there is no dedusting devices on liner boards or spring seats, about 25% dust will leak out and pollute the working environment. According to the above reason analysis, we give the following measures. To reduce the dust, we should control it from source. Feeding mouth and discharging mouth are the sources of dust.

We can cover the dusting points with hood, then use draught fun to take dust. Meanwhile, we can use the wet dedustor to clean air in a systemic way. The dust amount is related with the feeding amount of mineral stones and working efficiency of jaw crusher. While, the crushing efficiency is dependent on the key factors like density, wearing degree and type of cutting plate. 

Usually, mineral stones need to be screened firstly before being fed into jaw crusher. Only those stones with size larger than screen specification can enter into jaw crusher for crushing. If we can not clean the screen immediately, then a lot of small stones or stone powders will be fed. Due to this, a lot of dust will be produced.

To control the source of dust, we should make the screen clean all the time. See Price on website!
