However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15 0.20 EUR per ton of cement.

Ball Mill Design. Autogenous mills range up to 12 meters in diameter. The length to diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 11and 1.81. For fine regrinding in open circuit, the ratio ranges from 1.31 to 1.51.

RETSCH laboratory ball mills are available as mixer mills as well as planetary ball mills. Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. They are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery.

Keywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

grinding media distribution in ball mill. grinding media size distribution in ball mill. ball mill for cement grinding Versatile system based on standard modules 2 The ball mill is designed for grinding of clinker, gypsum and dry or moist additives to any type of cement.

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns.

Dry batch milling tests were performed in a laboratory scale ball mill measuring 30.2 by 28.2 cm. The mill specifications are given in Table 1. A constant ball load of 20% was maintained in all the tests with a ratio of 0.5 for binary and 0.33 for trinary ball mix. Table 1. Specifications of the mill.

a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the
