Truck Tippers are commonly used at Pulp and Paper facilities for wood chips, sawdust and hog fuel. DSI has many years of experience in dealing with these difficult dust sources.
At the truck tipper, our system is designed to suppress dust using two stages of attack. First by filling the dump pocket with fog prior to the actual dump from the truck. This "pre-fog" will supply a reservoir of fog-charged air that, when displaced by the falling material will attach to the airborne dust particles and settle them out in the hopper due to their increased mass. To do this, the fog manifolds at the dump hopper activate as soon as the tipper platform starts to rise.
Stage two is the same foggers operating during the complete dump cycle until the platform rests back on the ground. This stage will attack the creation of additional dust at the dump as the truck continues to dump.
Dry Fog is also used at the hopper discharge to the take-away conveyor and transfer points down-stream.
