1.Product Introduction
HOT Mining is a company specializing in design, production and sales of wear-resistant grinding ball. It is the leading brand of the grinding ball industry. Adopting the world's most advanced technology to produce grinding ball whose diameter is between 20mm and 160mm, annual production capacity is over 150 thousand tons. The main products of HOT are hot-rolled and new forging grinding balls. They are widely used in precious metal processing industries at home and abroad such as gold, nickel and copper, etc. The grinding ball of HOT occupies most of the world's high-end market with the international first-class R & D team, advanced production equipment and a number of domestic and international patent technologies.
2.Features
2.1.High Hardness: Surface Hardness:55-65HRC, Voumetric Hardness:54-62HRC
2.2.High Impact Toughness: ＞12J/CM²
2.3.Low Breakage Rate:Actual breakage rate is less than 1%
2.4.Roundness: Spherical with little overfill or underfill within the national standard: YB/T 091-2005
3.Technology
Special heat treatment is the key to HOT Grinding Ball’s superior quality. We have developed world’s first-class heat treatment lines. It applies of high temperature on-line thermomechanical treatment technique. The balls are rotating and quenching one by one through the special designed equipment in very short time. Homogenous and stable quenching quality ensures the high and uniform hardness of grinding balls. Fine grain and high impact toughness value ensures excellent wear ability of Yute Grinding Balls. With high technology content and high automation degree, the automatic producing lines designed and made by ourselves has effective controls on the whole process by computer. This avoided all artificial interferences and improved the products’ quality significantly .This cutting-edge computer control system is currently unique in the world.
