Cementos Santo Domingo, S.A., specializes in the grinding and shipping of cement for use in the construction sector. The plant has a Portland-type cement milling process, possible through an Allis Chalmer Ball Mill composed of two chambers 3.35 m in diameter and 9.75 m in length with an 80 Ton/h capacity. The existing girth gear, manufactured by Falk had been used prior to being installed at the Cementos Santo Domingo plant, wear was present as a result of prior operation period. At the beginning of the year 2000, it was necessary to flip the girth gear to use its unworn face in order to complete the gear life of 20 years of operation.
Using the pinion shaft the client had available as a baseline, the GIRTH GEAR was manufactured in 2 sections with an electrowelded structure. The outer ring is made of quenched and tempered forged steel to guarantee a hardness equivalent to 240-270 HB and has undergone ultrasonic testing.
The state of emergency resulting from the COVID-19 pandemic and restrictions on international travel proved challenging for the execution of this project. It was necessary to make different itinerary changes to complete the installation during the year-end holidays.
