Jan 08,2021
Reporters recently learned from the Municipal Bureau of Science and Technology that a drop ball testing machine with a drop height of 14 meters, accurate and reliable test data, and high stability was born at Goldpro New Material Co., Ltd.
Yin Wenxing, Deputy General Manager of Goldpro New Material Co., Ltd., introduced that this equipment is an important testing device for checking the anti-breakage ability and fatigue life of steel balls before they leave the factory, providing strong evidence and important guarantees for the safe and efficient operation of semi-autogenous mills and ball mills. Previously, the world's largest semi-autogenous mill had a diameter of about 13 meters and a drop height of about 10.5 meters. The drop ball testing machine produced by Goldpro New Material with huge investment has an effective drop height of up to 14 meters,
The testing intensity for the toughness and fatigue life of steel balls is higher than actual working conditions, fully meeting inspection requirements.
It is understood that after the drop ball testing machine was built, Goldpro New Material conducted multiple tests. After a single ball underwent more than 120,000 continuous drops, the steel ball showed no chipping, no deformation, and zero breakage. Every batch of steel balls produced by the company must be inspected by this drop ball testing machine to ensure qualification before leaving the factory. The feedback results from world-renowned mining companies after use are consistent with the data detected by the drop ball testing machine, and the steel balls supplied by Goldpro have a longer service life and higher hardness, effectively saving costs.
