During the wearing process in the ball mills, the hardness of forged balls decrease more quickly from the surface to the inside than for the high chrome grinding balls. Used forged balls have a low hardness than the high chrome balls at the same radius. Grinding parameters are in favor of high chrome grinding balls in the same conditions. Baudouin
Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles.

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .
Silver Lead Zinc Ore Processing Method using Flotation Sulphide ore of lead and zinc containing considerable silver was submitted for testing with the purpose of determining a flowsheet for the production of separate lead and zinc concentrates for marketing at their respective smelters.
The flowsheet uses a three stage closed circuit crushing section with a capacity of tons per 10 hours to reduce the ore to minus 12 mm for feed to the ball mill.

The grinding process studied in this paper operates in a closed loop as shown in Fig. 2, including a ball mill and a spiral classifier. The feed, iron ore (from primary crusher, size ≤ 14 mm) is fed into the ball mill by swaying tumbling action of the balls within the revolving mill crushes the feed to finer sizes.
The present literature review explores the energyefficient ultrafine grinding of particles using stirred mills. The review provides an overview of the different techniques for size reduction and the impact of energy requirements on the choice of stirred mills. It also discusses the factors, including the design, operating parameters, and feed material properties, influencing the grinding ...
Mechanical properties and particle size composition of a leadzinc ore in Yunnan were determined, and the problems such as low processing capacity of a section ball mill, substandard fineness and unreasonable particle size composition were solved through the contrast test of grinding medium. The experimental results show that the ore is medium hard and soft ore, with uneven distribution, and ...
