Improved Coal Dust Collector

Martin Engineering has introduced an upgraded version of the MARTIN Insertable Dust Collector, which features improved filters and a smaller footprint to control airborne coal dust at belt conveyor loading points and other bulk material-handling operations. Insertable dust collectors are typically installed to reduce problems associated with central baghouse collection systems, including long runs of ducting, large enclosures, maintenance difficulties, and high power consumption.

The improved collector’s filter elements are approximately one-eighth the size of the previous system’s filter envelopes. The mesh-like material filters better and lasts longer while consuming less energy than conventional filter bags. The upgraded filters also allow a reduction in the size of the fans used to move air through the filter elements, therefore reducing the system’s power consumption. Another unique feature of the collector is its pulse-cleaning system, where a short pulse of air is sent back through the filter to dislodge accumulated material. (
