In the process of crushing, it is very necessary to reduce the dust to prevent dust pollution. Following is the methods to reduce the dust in production line:
1. In the point of dust source setting the sprinkler systems, dust collection device and sealing cover, etc.
(1) Should set two spray systems in the feed inlet, outlet and crushing chamber separately. Two spray header of feed inlet point to the inlet, another two spray header of outlet to spray crossed water in a relative angle to get the best effects.
(2) Install the dust-suction device in the repair hole of the crusher and the discharge opening. The dust-suction device should be installed 1000mm away from the discharge opening. The surface of the dust-suction device should be vertical with the dust flowing direction.
2. Modify the structure of large inclination such as hopper, dust-proof cover, chute etc.
Solution: One is to smaller the angle of inclination of chute to reduce the static energy of the material, the other is to modify the crusher structure, such as add number of teeth in the toothed plate.
3. Besides the above measures, the unreasonable technological process and the block of screen will increase producing the dust. Therefore, try best to use the most advanced technology and transfer the material in a closed way.
