Conveyor and Transfer Point Dust Control Nozzles

Preventing or suppressing dust created by moving, transferring, and storing minerals and aggregates on conveyors.


The movement of conveying crushed stone, coal, or sand, stirs up and creates a dust cloud, which can be suppressed by spraying water as a fine mist or fog. Adding finely sprayed water to the minerals or aggregates on conveyors or at transfer points and hoppers can prevent the generation of dust or suppress created dust clouds and keep them from spreading. The sprayed water can prevent the dust cloud from forming by adhering the dust to the mineral being processed or agglomerating with the dust particles in the air. Effective dust control on conveyors and transfer points can also play a critical role in preventing dust explosions and be a key safety system in processing plants and power generation facilities.

For preventative dust control to be effective, coverage and distribution is essential. Ensuring complete coverage of the material being transferred ensures proper wetting of all the material and prevention of dust formation. However, over-spray can waste resources and lead to build-up on other portions of transfer equipment. In many applications, surfactants or foaming chemicals are added to help the sprayed water to effectively cover and penetrate material being transferred on a conveyor.

For airborne dust suppression to be effective, it is crucial to get the right sized droplet. In most applications, droplets should be 1 to 5 times the size of the dust that is being controlled. If the drops are too small, they will be unable to agglomerate with and knock down the dust particles. Conversely, water drops that are significantly larger than the dust particles form an air barrier around themselves, preventing the dust from gaining direct contact and encapsulation/agglomeration with the water droplet.
 

Selecting a Conveyor and Transfer Point Dust Control Nozzle:

Important factors to consider:

  • Prevention vs. suppression water spray systems
  • Dust particle size and concentration
  • Amount of raw material and conveyors speeds
  • Required coverage
  • Available nozzle mounting locations
  • Available and allowable water flow rates
    • Sufficient water to effectively prevent or suppress dust is required but too much water addition can create binding / clogging of downstream equipment, effect the transport costs of materials, or effect the BTU content of coal among other factors
  • Available liquid pressure drop (∆P) across the nozzle(s)
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
