65,000 kilos girth gear for project in Armenia A girth gear of gigantic dimensions is produced in South Africa for a project in Armenia. F L Smidth Minerals has ordered a nearly 65,000 kilos girth gear for a project in Armenia, it is produced 8,000km away by David Brown Gear Industries (DBGI) in South Africa. The single helical SAG mill girth gear is cast in four pieces, has 362 teeth, 0.75 DP, 863,6mm face width, 12.4m outside diameter and a 10.5m diameter bore. It is manufactured from steel with a hardness range of 269/321 BHN and the gear teeth are cut to AGMA grade 10. Furthermore three mill pinions to suit the girth gear are supplied, each with 18 teeth, 3810 mm overall length, and weighing 5,090 kilograms. The gear is being cut on the MAAG 14m gear cutting machine and the pinions ground on their newly acquired state-of-the-art 3m Niles Grinder machine. In collaboration with Scaw Metals the gear is finalized in order to deliver it to the client on time. Scaw Metals supplies the castings for the job to DBGI. Of the complex engineering challenges that this project poses perhaps one of the major difficulties is coping with the location where the equipment will be installed in Armenia. When manufacture is complete the gear will be dismantled and shipped to its destination in four parts. Armenia is the smallest of the former Soviet republics and is land locked by Georgia in the north, Azerbaijan in the east, Iran to the south                                                                                              and Turkey to the west.
