2 Inch Grinding Balls
The 2 inch grinding balls offer a perfect balance between impact force and abrasion resistance, making them suitable for both rough grinding and finish grinding stages. Their high surface hardness combined with a tough core ensures longer service life and less ball consumption. With lower wear rates, you can expect reduced mill downtime and improved grinding efficiency, ultimately lowering overall production costs.
Product Overview
2-inch grinding balls are specially manufactured for mid-to-fine grinding operations, widely used in mining plants, cement factories, and thermal power stations. We use premium alloy steel to forge these balls and apply a carefully controlled heat treatment process to ensure a hardness of HRC>60. This gives the balls excellent strength, wear resistance, and consistency during demanding milling tasks.
