In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
These grinding media are same-sized and can be used to crush virtually any material in a ball mill without wreaking havoc on the latter. That is why they outperform their steel counterparts, finding a range of applications in dyestuff, pigment, cement, food processing, mining, and other industries.
An online calculator lets you calculate Top Ball Size of Grinding Media for your mill. Use this Equation & Method to properly grind your ore.
The performance of ball mill depends on number, size and density of balls, flow rate of . For commercial cement plant ball mill 12 m long, 3.8 m diameter, calculations Get Price. Basic Comminution Concepts and Recent Trends in the Industry Tumbling mills for size reduction with either steel rods (rod mills) or balls (ball For practical calculations the size in microns which 80%

01.11.2017· Cement Mill Grinding Media. Dear Experts, I want to know about the GM size wise percentage distribution in a 2 chamber close circuit OPC ball mill. Mill dim. 3.4 x 12.5. Media load 128 MT high chrome. Also let me know how do the supplier selected 80mm as max. Ball size in this mill? Please share the formula as well.
Conventionally, grinding media was made of Cast iron, Cast steel and even through Forged process in EN specifications. However, High Chrome Grinding media has surpassed the conventionally produced grinding media in terms of performance and is now widely being used by all industries across the globe.
A cement mill (or finish mill in North American usage) mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter). Ball diameter here is in the range 60–80 mm. In a two-chamber mill, the media in the second chamber are typically in the

01.09.2013· A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes (50.8 mm and 25.4 mm)
18.07.2016· Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position. The current way to measure the charge filling degree

Ball diameter here is in the range 60–80 mm. In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered.
Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
