How To Deal With The Dust Pollution in The Shredder Operation?

1. Water spray to eliminate dust
Set water spraying devices at the material inlet, material outlet and shredding chamber of the shredder, and set two water nozzles at each place. Among them, the two nozzles at the material inlet point to the material inlet; the two nozzles at the material outlet form a certain angle relative to each other, so that the sprayed mist water forms a cross state to achieve the best spray effect; the nozzles at the shredding chamber are set at the dynamic Jaws behind, at an angle to the horizontal.
2. Dust removal
Vacuum cleaners are respectively installed at the discharge port of the jaw crusher and the inspection port at the rear of the movable jaw of the shredding chamber to control the spread of dust by means of dust collection. Among them: the dust collection hood of the vacuum cleaner at the discharge port is about 1 meter away from the discharge port, and the plane of the dust collection cover is perpendicular to the direction of dust flow; the connecting air duct between the dust collection cover of the vacuum cleaner and the fan after the movable jaw is designed as a scalable pipe , to facilitate refueling and daily maintenance of the shredding motor jaw.
3. Reasonable selection of gear plate
When selecting a tooth plate, it is necessary to choose a tooth plate with a relatively large number of teeth and a small tooth shape, which is conducive to improving the shredding efficiency and reducing dust generation.
4. The tooth plate should be fixed firmly and reliably
During the operation of the shredder, frequent impact loads will be generated, and the ore and the tooth plates are frequently impacted and squeezed, and the fixed tooth plates and the movable jaw tooth plates are prone to loosening or falling off. Once the tooth plate is loose or falls off, the shredding efficiency of the shredder will be greatly reduced, causing the ore to stay in the shredding chamber for a long time, resulting in repeated friction between the ore and the tooth plate to generate a large amount of dust. Therefore, the tooth plate must be fixed reliably, which also reduces the generation of dust from the source.
5. Replace the blunt tooth plate in time
When the tooth plate is blunted, it will increase the contact area with the ore, consume a lot of shredding power, and also cause a lot of dust, so the blunt tooth plate should be replaced in time.
6. Properly increase the traction speed of the output product of the shredder
Adjusting the subsequent conveying speed of the discharged product can not only make the shredder achieve the best working condition, but also achieve the effect of controlling dust. Therefore, while ensuring the tolerance range and production capacity of the following processes, the traction speed is appropriately increased, and the amount of secondary dust raised is small.
7. Humidification of materials
In order to keep the whole set of dust prevention measures in a relatively stable state and to better control the overall dust concentration, in the actual production process, the raw ore before entering the shredder is humidified, which can effectively reduce the ore in the shredding process. Dust rate produced.
