With more than 100 years of experience in ball mill technology, Outotec ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

The closed-circuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plant. There are many factors that may affect the ball mill's working efficiency and product quality during the operation. In this article, we will discuss the measures that can improve the ball mill's performance.For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

All of the samples exhibited high capacity retention throughout the continuous charge–discharge process. The capacity retention of the LFP, LFP_B, and LFP_B + C cathodes after 50 cycles was 95.4, 95.7, and 98.0 %, respectively. Modifying the LFP with the ball-mill and carbon coating can improve its cycling capacity performance considerably.Ball Mill Advantage. 1.Suitable for grinding material with high hardness. 2.The shape of the final products is circular. 3.No pollution for the powder with ceramic ball. 4.Stable performance Easy installation. 5.The capacity and fineness can be adjusted by adjusting the diameter of the ball.

Thankfully, the performance of the vertical mill was still better than the ball mills, which reinforces the use of this technology.performance. The tests were completed in a Labtech Essa laboratory mill that was 200mm in diameter and 250mm long. The mill was operated at 75RPM with an ore mass of 1kg. The ball charge in the mill comprised of three ball sizes and the mass distribution of the size fractions are detailed in Table 1. Table 1. Ball Charge Mass Distribution
