Martin Transfer Point Products Reduce Risk Of Fire Or Explosion


A Martin® Light Duty Impact Cradle was installed under the loading zone of Conveyor #9.

At a power plant in Georgia, fugitive material was escaping from the coal-handling systems as excessive dust and spillage. To boost material handling efficiency and reduce the risk of fire or explosion, Plant Jack Mac personnel sought to improve the performance of their conveyor system.


Martin® ApronSealTM Skirting was installed on the outside of the new 12-inch (304-mm) skirtboard.

To improve conveyor performance, Georgia Power selected MartinPLUS® Services to rebuild the loading zone on Conveyor #9. Included in the project were installations of taller and longer skirtboard walls, new belt support systems, abrasion-resistant wear liners, and a multi-layer, low-pressure sealing system on the outside of the chute walls.


A Martin® Tail Sealing Box with Martin® Steel Inspection Door was installed to prevent material from spilling out the back of the loading zone.

During a four-day outage, technicians from MartinPLUS® Services rebuilt the load zone on Conveyor #9. The three man crew removed the existing 20 degree idlers and installed one Martin® Light-Duty Impact Cradle and four Martin® Support Cradles with center rollers.

They also installed 22 feet (6.7 m) of skirtboard on each side of the conveyor, and added abrasion-resistant Martin® Wear Liner on the 12-inch (304-mm) high chute wall. Installation of Martin® Apron Seal Skirting System, a Martin® Tail Sealing Box and Martin® Dual Dust Curtains completed the reconstruction of the transfer point.

The MartinPLUS® Services installation crew worked on the project on second- shift schedule. At the end of each day’s work, the crew restored the conveyor to service, allowing the plant to operate. The project resulted in a great improvement in transfer point performance.
