Examples - XFoam Dust Suppression
| Quarry and other bulk material processes such as crushing screening and all material transfers are the prime source of dust emissions. XFOAM can dramatically reduce the dust from all these operations |
INJECTION of XFOAM into the input throat of the crushing machine. Use with Jaw crushers, Hammermills, Impact crushers, Ball Mills, Conical Crushers etc. Since XFOAM is very stable and only breaks down by the influence of time, temperature, or contact with small particles of less than 30 microns in diameter, the foam will travel through the crusher without substantial degradation, unless the machine is reducing the size of the aggregate and thus producing dust particles. |
CRUSHERS are principal dust creating source in mineral processing. By using XFOAM it is possible to suppress dust as it in created "in the crusher". LAYERING of XFOAM on top of the aggregate being transported into the crusher is another way of assuring that foam comes into contact with dust particles as they are produced by the fracture of the material. |

DUST FROM HOPPERS When dusty material is dropped into hoppers the air displaced by the material carries the small particles out into the environment. By placing a blanket of XFOAM across the top of the hopper much of the dust is trapped when the displaced air moves upwards. Foam nozzles are mounted in the corners of the hopper. The system can be activated manually by the operator, automatic by pressure switches, line of sight device, or by radio transmitter |

| SCREW CONVEYORS
XFOAM is injected into the side of the screw conveyor about 1.5m (5 ft.) from the discharge end so that the rotation of the screw carries the foam and the material downward towards the bottom of the trough. The action of the screw conveyor thoroughly mixes the XFOAM and the material. |

Xfoam used in Cyclones
XFOAM is injected into the inlet air stream containing the particulates. The centrifugal force causes the foam to coat the sides of the chamber. As particles strike the walls of the chamber they break down the foam and produce a slurry of particulate matter. This can be discharged periodically from the bottom of the chamber through a rotary seal or counter-weight gate. A simple cyclone can be made 99.99% efficient by the injection of XFOAM along with the input air. |
