An overflow ball mill passed the factory acceptance test and was delivered to its customer in Luoyang City, central China's Henan Province, on Tuesday.

With a diameter of 8.2 meters and a length of 12.7 meters, this overflow ball mill is said to be the largest one made in China, marking a breakthrough in the country's large-scale grinding equipment manufacturing.

It will be exported to a Chinese-funded mining company in Ghana, Africa, for gold mine production.

The ball mill adopts a number of core technologies, such as three-dimensional parametric design, smart load-sensing system and large gears manufacturing, said Tang Biliang, chief designer of the ball mill at the CITIC Heavy Industries Co., Ltd.

It also achieved breakthroughs in terms of technical performance, process manufacturing and processing cycle, Tang added.
