Consumption of steel grinding media in mills – A review

2013.8.1 According to Moema et al. (2009), in some instances, media wear can constitute up to 40–45% of the total cost of comminution. An estimated consumption of steel grinding media of around 600,000 tons p.a. in the 1980s already gives an indication of the scale of the problem (Malghan, 1982). Likewise, in the cement industry, as mills

The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is 30-45 percent lower for cement grinding and 40-50 percent lower for slag. The ...

Grinding ball data - INFINITY FOR CEMENT EQUIPMENT

Independent of the chrome-content of the grinding balls, the specific wear rate of the grinding media var ies approximately from 15-110 grams per ton of cement. This depends on the different tempering pro cess of the grinding media. Table 7.7.3.1. contains a compilation of wear rates of grinding media with 59 Rc hardness (comparable ...

Grinding in Ball Mills: Modeling and Process Control - Sciendo

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].
